Abstract:

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.
The purpose of this thesis is the design and implementation of the pedal box for the 2007 MIT Formula SAE car. Formula SAE is a collegiate competition in which groups of degree seeking students design and manufacture small formula style race cars to compete on design, cost, marketing, and performance. The pedal box is an integral part of the vehicle as the driver directly interacts with it making ergonomic considerations integral to the success of the design. The 2007 pedal box design emphasizes design for manufacture, adjustability, ergonomics and weight savings. An innovative design decreases the amount of space needed for the pedal box through the use of vertically mounted master cylinders while allowing for the d.river to adjust front to rear brake bias, brake pedal ratio, and location in the car. The design also causes a significant reduction in complexity and weight through a decrease in the number of components needed for manufacture.

The design requirements for the new electric powertrain were the ability to deliver the peak power of 80kw allowed by rules and meet the mass goal of 23kg. Rear wheel independence needed to be maintained either through a multi-motor design or a differential, but with vehicle performance in mind. Stiffness of the mounting system was another goal, as the previous design had lateral deflections larger than deemed acceptable. Along with system design requirements, various components and packaging options were considered. Preliminary design and estimation coupled with fundamental engineering rational focused the design to a particular setup. In parallel with system design, analysis was performed to select materials, geometry, bearings, and hardware. Load cases were analyzed to determine how FEA simulations would be set up. Failure modes checked were primarily yield conditions, but stiffness of the mounting plates was also analyzed to ensure the system met the max deflection goal of 0.005". The final design included a single three phase electric motor capable of up to 100kW peak with a limited slip differential, and a mass reduction of almost 45% over the previous powertrain, meeting the mass goal. Eccentric rings allow for easy chain tensioning. A simple 6 bolt mounting system makes the self-contained unit easy to remove from the frame, and overall stiffness is improved from the previous design.

Abstract:

In questo elaborato si analizza l’aerodinamica di un veicolo di categoria Formula facendo una revisione delle fonti più aggiornate. Vengono, poi, studiate le tipologie di gallerie del vento, le tecniche e le strumentazioni utilizzate in ambito automotive. Infine, viene proposto uno studio preliminare per realizzare un test in galleria del vento con la UBM19, la vettura di Formula SAE del team UNIBO Motorsport, con lo scopo di avere una validazione del modello CFD e confrontarne i risultati anche con quelli ottenuti nei test su pista. Per diminuire complessità e costi, si suggerisce di eseguire un esperimento con ruote e suolo fermo. Si definisce perciò la tipologia di galleria e la strumentazione necessaria, eseguendo anche una prima stima dell’errore dovuto alla staticità di suolo e ruote utilizzando simulazione CFD.

This thesis will analyze the MIT Formula SAE car to determine performance of our current and future cars. The conclusion of this analysis will drive the powertrain decisions for our Model Year 2017 (MY 17) and other future cars. Very little data relating to our cars currently exists, but is vital to proper design; therefore, that is the first step of this thesis. After current performance has been gaged, the next step will be determining a motor that will optimize vehicle performance for competition. From this our team could use either two motors with an electronic differential or one motor with a limited slip differential. Tangential to determining motors, analysis will also be done to determine whether chains or a planetary gear system would be more optimal for connecting the motor output to the rear wheels.

The suspension geometry is the foundation of a performance vehicle's design because it dictates the overall packaging constraints and the connection between the chassis and the tires. This thesis details the design process used to produce the suspension geometry for MIT Motorsports' 2018 Formula SAE car and the justification for each design decision made. A thorough iteration process was used to prevent compromises that could significantly detract from specific component performance in order to meet suspension kinematic requirements. Using this process, the kinematic performance of the suspension was maximized by minimizing the roll center's movement and designing the tire camber change characteristics to achieve 0° of outer-wheel camber while at the car's maximum lateral acceleration.

Abstract:

The problem with designing and simulating a race car entirely through CAD and other computer simulations, is that the real world behavior of the car will differ from the results outputted from CFD and FEA analysis. One way to learn more about how the car actually handles, is through telemetry and data logging of many different sensors on the car while it is running at racing speeds. This data can help the engineering team build new components, and tune the many different systems on the car in order to get the fastest time around a track as possible.

A case study was performed on the financial reporting at the MIT Formula SAE team. For each section of the car it was necessary to provide three main financial documents: Bill of Materials, Process Descriptions, and Fasteners. Additionally, the team had to adhere to specific guidelines for preparing these documents and for compiling them all together to create the team's cost report. The purpose of the case study was threefold. First, it was intended to improve upon the quality and score of the cost report from previous years. Second, it was intended to alleviate some of the pressure from the team managers by not having to worry about preparing the cost report themselves. Finally, the case study was intended to help facilitate the preparation of the cost report in future years, so it does not have to be overshadowed by the completion of the vehicle. Therefore, the trend of increasing performance of the cost report can be maintained. In the end, the study proved to increase the team's cost report score, allowed the team managers to focus more on the production of the vehicle, and yielded templates and instructions, as well as a standard, for preparing future cost reports.

This thesis documents the design and analysis of the enclosure for the high voltage battery pack which powers the Model Year 2017 MIT Formula SAE racecar. The battery pack is custom designed and built with six modules of 144 Samsung INR18650-25R lithium-ion cells each. Each component of the enclosure is analyzed to ensure structural integrity and optimized to reduce mass of the battery pack. The enclosure is able to secure the modules during sudden accelerations or decelerations from crash scenarios, allows for air flow to cool the cells, and allows for convenient serviceability of the modules. The final mass of the enclosure, at 8.5 kg, results in an overall battery pack mass of 59.5 kg, 76% of the mass of the Model Year 2016 battery pack. All components of the enclosure have been manufactured, and the assembly process with the modules and high voltage electronics has been tested and verified.

Designing and constructing a chassis and suspension system for a Formula SAE racecar is a highly complex task involving the interaction of hundreds of parts that all perform an essential function. This thesis examines the critical factors in designing and implementing a Formula SAE chassis from the ground up, with a focus on the performance and optimization of the vehicle as an entire system rather than a collection of individual parts. Analysis includes examining the stiffness, strength, and weight of each part, as well as design verification. The thesis will serve as a summary of the knowledge that I have accumulated over four years of personally designing and overseeing the manufacturing of the MIT Motorsports suspension, provide insight into the design of the MY2009 vehicle, and act as a guide for future chassis designers.

Abstract:

Nel presente elaborato viene riassunta in 4 brevi capitoli la mia attività di tesi, svolta nell’ambito del progetto Formula SAE® dell’Università di Bologna nell’anno 2010. Il progetto ha consistito nella realizzazione di una vettura monoposto, con l’obiettivo di far competere la stessa negli eventi previsti dalla SAE® (Society of Automotive Engineer), insieme alle vetture progettate e costruite da altri atenei di tutto il mondo. In tali eventi, una serie di giudici del settore auto-motive valuta la bontà del progetto, ovvero della vettura, che sarà sottoposta ad una serie di prove statiche e dinamiche. Nella seguente trattazione si narra quindi il percorso progettuale e di realizzazione del telaio della vettura, ovvero della sua struttura portante principale. Il progetto infatti, nell’ambito del team UniBo Motorsport, mi ha visto impegnato come “Responsabile Telaio” oltre che come “Responsabile in Pista” durante le prove su strada della vettura, svolte a valle della realizzazione. L’obbiettivo principale di un telaio di vettura da corsa è quello di realizzare una struttura che colleghi rigidamente tra loro i gruppi sospensivi anteriore e posteriore e che preveda anche la possibilità di ancorare tutti i componenti dei sistemi ausiliari di cui la vettura deve essere equipaggiata. Esistono varie tipologie di telai per autovettura ma quelle più adatte ad equipaggiare una vettura da competizione di tipo Formula, sono sicuramente il traliccio in tubi (“space frame”) e la monoscocca in fibra di carbonio. Il primo è sicuramente quello più diffuso nell’ambito della Formula Student grazie alla sua maggior semplicità progettuale e realizzativa ed ai minor investimenti economici che richiede. I parametri fondamentali che caratterizzano un telaio vettura da competizione sono sicuramente la massa e la rigidezza. La massa dello chassis deve essere ovviamente il più bassa possibile in quanto quest, costituisce generalmente il terzo contributo più importante dopo pilota e motore alla massa complessiva del veicolo. Quest’ultimo deve essere il più leggero possibile per avere un guidabilità ed una performance migliori nelle prove dinamiche in cui dovrà impegnarsi. Per quanto riguarda la rigidezza di un telaio, essa può essere distinta in rigidezza flessionale e rigidezza torsionale: di fatto però, solo la rigidezza torsionale va ad influire sui carichi che si trasferiscono agli pneumatici della vettura, pertanto quando si parla di rigidezza di un telaio, ci si riferisce alla sua capacità di sopportare carichi di tipo torsionale. Stabilire a priori un valore adeguato per la rigidezza torsionale di un telaio è impossibile. Tale valore dipende infatti dal tipo di vettura e dal suo impiego. In una vettura di tipo Formula quale quella oggetto del progetto, la rigidezza torsionale del telaio deve essere tale da garantire un corretto lavoro delle sospensioni: gli unici cedimenti elastici causati dalle sollecitazioni dinamiche della vettura devono essere quelli dovuti agli elementi sospensivi (ammortizzatori). In base a questo, come indicazione di massima, si può dire che un valore di rigidezza adeguato per un telaio deve essere un multiplo della rigidezza totale a rollio delle sospensioni. Essendo questo per l’Università di Bologna il primo progetto nell’ambito della Formula SAE® e non avendo quindi a disposizione nessun feed-back da studi o vetture di anni precedenti, per collocare in modo adeguato il pilota all’interno della vettura, in ottemperanza anche con i requisiti di sicurezza dettati dal regolamento, si è deciso insieme all’esperto di ergonomia del team di realizzare una maquette fisica in scala reale dell’abitacolo. Questo ha portato all’individuazione della corretta posizione del pilota e al corretto collocamento dei comandi, con l’obbiettivo di massimizzare la visibilità ed il confort di guida della vettura. Con questo primo studio quindi è stata intrapresa la fase progettuale vera e propria del telaio, la quale si è svolta in modo parallelo ma trasversale a quella di tutti gli altri sistemi principali ed ausiliari di cui è equipaggiata la vettura. In questa fase fortemente iterativa si vanno a cercare non le soluzioni migliori ma quelle “meno peggio”: la coperta è sempre troppo corta e il compromesso la fa da padrone. Terminata questa fase si è passati a quella realizzativa che ha avuto luogo presso l’azienda modenese Marchesi & C. che fin dal 1965 si è occupata della realizzazione di telai da corsa per importanti aziende del settore automobilistico. Grazie al preziosissimo supporto dell’azienda, a valle della realizzazione, è stato possibile condurre una prova di rigidezza sul telaio completo della vettura. Questa, oltre a fornire il valore di rigidezza dello chassis, ha permesso di identificare le sezioni della struttura più cedevoli, fornendo una valida base di partenza per l’ottimizzazione di telai per vetture future. La vettura del team UniBo Motorsport ha visto il suo esordio nell’evento italiano della Formula SAE® tenutosi nel circuito di Varano de Melegari nella prima settimana di settembre, chiudendo con un ottimo 16esimo posto su un totale di 55 partecipanti. Il team ha partecipato inoltre alla Formula Student Spain tenutasi sul famoso circuito di Montmelò alla fine dello stesso mese, raggiungendo addirittura il podio con il secondo posto tra i 18 partecipanti. La stagione si chiude quindi con due soli eventi all’attivo della vettura, ma con un notevole esordio ed un ottimo secondo posto assoluto. L’ateneo di Bologna si inserisce al sessantasettesimo posto nella classifica mondiale, come seconda università italiana.

Abstract:

Il seguente lavoro di tesi è finalizzato alla realizzazione dell’elettronica di controllo per una vettura prototipo, Nel Capitolo 1 della tesi viene descritto più nel dettaglio il progetto Formula SAE, introducendo gli aspetti peculiari della competizione; successivamente segue una breve descrizione del team UniBo Motorsport. Il Capitolo 2 descrive l’elettronica implementata nella stagione 2013 evidenziandone i punti di forza e le debolezze al fine di poter trarre delle conclusioni per comprendere la direzione intrapresa con questo lavoro di tesi. Nel Capitolo 3 viene presentata la soluzione proposta,motivandone le scelte e la necessità di suddividere il lavoro in più unità distinte, mantenendo le peculiarità tecniche del già eccellente lavoro effettuato nel corso degli anni da chi mi ha preceduto ed aggiungendo quelle funzionalità che permettono di mantenere la soluzione in una posizione dominante nel panorama della Formula Student. La progettazione dell’hardware che compone la soluzione proposta è descritta nel Capitolo 4, introducendo dapprima la metodologia adottata per la progettazione partendo dalle specifiche fino ad arrivare al prodotto finito ed in seguito ne viene descritta l’applicazione ad ogni unità oggetto del lavoro. Sono state progettate da zero tre unità: una centralina di controllo motore (ECU), una di controllo veicolo (VCU) ed un controller lambda per la gestione di sonde UEGO. Un aiuto fondamentale nella progettazione di queste tre unità è stato dato da Alma Automotive, azienda che fin dal principio ha supportato, anche economicamente, le varie evoluzioni dell’hardware e del software della vettura. Infine viene descritto nel capitolo 5 il software che verrà eseguito sulle unità di controllo, ponendo particolare risalto al lavoro di adattamento che si è reso necessario per riutilizzare il software in uso negli anni precedenti.

Formula SAE is a collegiate design competition in which student teams design, build, and race an electric formula racecar every year. In 2019, the MIT team built its first four wheel drive vehicle. The new architecture requires more robust and performant control systems. One major challenge is that the vehicle is not functional for the majority of the year. A longitudinal vehicle simulation was written and tested for the purpose of testing control algorithms without a physical testbed, as well as to learn more about vehicle behavior in general. The simulation was written in Simulink and the structure kept versatile so that it could be easily expanded in complexity in future years. Test data was used to successfully correlate the model to the actual system. Several launch control algorithms were also tested using this simulation, for both a rear wheel drive and four wheel drive architecture. Although basic, the control schemes produced promising results for both speed and stability, notably the normal force proportional controller.

Abstract:

The Texas A&M University Formula SAE program currently has no rigorous method for analyzing or predicting the overall dynamic behavior of the student-designed racecars. The objective of this study is to fulfill this need by creating a full vehicle ADAMS/Car model incorporating an empirical tire-road force model and validating the longitudinal performance of the model by using vehicle responses recorded at the track. Creating the model requires measuring mass and inertia properties for each part, measuring the locations of all the kinematic joints, testing the Risse Racing Jupiter-5 shocks to characterize damping and stiffness, measuring engine torque, and modeling the tire behavior. Measuring the vehicle performance requires installation of the Pi Research DataBuddy data acquisition system and appropriate sensors. The 2002 Texas A&M University Formula SAE racecar, the subject vehicle, was selected because it already included some accommodations for sensors and is almost identical in layout to the available ADAMS/Car model Formula SAE templates. The tire-road interface is described by the Pacejka ??94 handling force model within ADAMS/Car that is based on a set of Goodyear coefficients. The majority of the error in the model originated from the Goodyear tire model and the 2004 engine torque map. The testing used Hoosier tires and the 2002 engine intake and exhaust configuration. The deliverable is a full vehicle model of the 2002 racecar with a 2004 engine torque map and a tire model correlated to longitudinal performance recorded at the track using the installed data acquisition system. The results of the correlation process, confirmed by driver impressions and performance of the 2004 racecar, show that the 2004 engine torque map predicts higher performance than the measured response with the 2002 engine. The Hoosier tire on the Texas A&M University Riverside Campus track surface produces 75??3% of peak longitudinal tire performance predicted by the Goodyear tire model combined with a road surface friction coefficient of 1.0. The ADAMS/Car model can now support the design process as an analysis tool for full vehicle dynamics and with continued refinement, will be able to accurately predict behavior throughout a complete autocross course.

Abstract:

Questo lavoro di tesi tratta della conversione di un motore a combustione interna ad accensione comandata PFI dall’utilizzo di benzina RON95 all’utilizzo di etanolo E85. L’applicazione dello studio riguarda il propulsore della vettura Formula SAE dell’Università di Bologna. In una fase iniziale dello studio si valutano dal punto di vista teorico gli aspetti inerenti il cambiamento di combustibile: confronto proprietà fisico-chimiche (calore latente di vaporizzazione, tonalità termica, numero di ottano), calcolo delle emissioni di CO2, rapporto di compressione, confronto strozzature da regolamento, stima della capacità del serbatoio. Nella parte centrale si approfondiscono le modalità con cui sono stati effettuati gli interventi in vettura e sul propulsore: incremento del rapporto di compressione, simulazione e progettazione venturi e valvola a farfalla, scelta degli iniettori, strategia di controllo pompa carburante, compatibilità dei materiali. Nella parte conclusiva vengono descritte le modalità di calibrazione del sistema di controllo in sala prova motori: calibrazione base dei rendimenti volumetrici e dell’anticipo di accensione, calibrazione avanzata e generazione curve ad ombrello. Le conclusioni riassumono pro e contro dello studio.

An improved shifting system for use with the MIT Formula SAE race car was designed in order to provide drivers with a faster and easier means of shifting. The result of this design was a pneumatic shifting system weighing just 3.6 pounds and capable of shifting the car's transmission in 200ms (downshifts are slightly slower because they require the use of the clutch). Shifts are initiated through buttons on the steering wheel and controlled through the car's engine control processor. An ergonomic clutch was also designed in order to help shift more easily and provide more control of the vehicle. This document describes, from beginning to end, the design process involved in creating these systems and provides justification for each decision that was made along the way.

The Formula SAE chassis provides a number of functions: it protects the driver during high speed operation, links critical components such as the engine, drivetrain, and suspension together through a rigid structure, and distributes forces through the frame to allow for predictable handling and kinematics. This document examines and analyzes the critical factors in designing and building a Formula SAE chassis from 4130 chromoly steel tubing. The paper focuses on several main design issues and criteria, provides a detailed description of the manufacturing and jigging process, and also documents verification testing of the real chassis against the CAD and FEA models. The thesis will serve three functions: first as a summary of lessons I have learned about product development from personally overseeing the fabrication of the MIT Motorsports chassis for 3 years (MY2006 - MY2008), second as a guide for future generations of chassis engineers in frame design and construction, and third as a specific study and verification of the theoretical methods behind the current vehicle design.

This thesis explores the design of a water cooled cold plate system for motor controller used in an FSAE Electric racecar. Models for pressure drop and rate of heat transfer along with the constuction of Computational Fluid Dynamics (CFD) simulations are presented to predict the pressure drop and heat transfer rate. The goal is to provide a framework to design cold plates for motor controllers, along with any other components that generate heat, such as the vehicle battery. A test bench is constructed to validate the results of the models used. Preliminary results show that while such models are useful in understanding the fundamental relationships between different variables and the properties of the flow, it is difficult to construct a model that predicts pressure losses reliably using introductory material on thermodynamics and heat transfer.

Abstract:

Scopo del presente lavoro di Tesi, è quello di affrontare il processo di progettazione della monoposto da Formula SAE dell’Università di Roma “Tor Vergata”. Come è noto, la Formula SAE è una manifestazione sportiva nella quale le migliori facoltà di ingegneria del mondo si cimentano nella progettazione, realizzazione e guida di piccole monoposto da competizione. La competizione non si limita semplicemente ad una gara di velocità tra autovetture ma scopo di questa è il Progetto del veicolo, in tutti i suoi aspetti: progettuale, economico e realizzativo. In questo lavoro si vuole decrivere l’iter progettuale seguito per la realizzazione della monoposto dell’Università di Roma “Tor Vergata” che ha debuttato per la prima volta nella Competizione in occasione dell’evento di Fiorano 2008. In particolare, la progettazione della monoposto si è avvalsa in maniera estensiva delle moderne metodologie di progettazione al calcolatore, mediante le quali è stato possibile l’abbattimento dei tempi di prototipazione e sviluppo e dei conseguenti costi. Esteso impiego è stato fatto di modelli ad elementi finiti per la valutazione del comportamento strutturale del telaio e delle sospensioni. Per queste ultime, si è proceduto inoltre ad effettuare una simulazione dinamica per mezzo di appositi tool. Il comportamento dinamico dell’intero veicolo è stato quindi valutato per mezzo di un modello multibody per mezzo del quale sono state determinate le massime performance della vettura e le influenze che su queste hanno i parametri di setup. Inoltre, al fine di valutare il comportamento della vettura quando questa si trova su pista, è strato sviluppato un apposito strumento che consente di effettuare la simulazione del giro di pista del veicolo, consentendo di apprezzare l’effetto delle variazioni nei parametri di setup sul principale indice di merito di un veicolo da competizione: il tempo sul giro.
Scope of the present work is to deal about the design process of the Formula SAE vehicle of the University of Roma “Tor Vergata”. As it is known, Formula SAE is a competition in which the best engineering faculties of all the world challenge theirselves in the design, manufacturing and driving of little race vehicles. The competition is not only limited to a speed contest but takes into account all the main aspects related to a Project: engineering design, manufacturability and costs. In this thesis work, all the design steps taken for the realization of the University of Roma “Tor Vergata” vehicle are described. In particular, car design has been widely based on modern CAE methodology and tools, that allowed to save money and time during the design process. A wide use of FEA has been dedicated to the structural design of chassis and suspensions. The latter have been also dynamically evaluated by means of dedicated tools. The dynamic behaviour of the whole vehicle has then been evaluated using a multibody model of the race car, that allowed to discover vehicle performances and the influence of setup parameters on them. Finally, in order to evaluate overall car performances when this is racing on a track, a custom lap time simulation (LTS) model has been developed.

Abstract:

Each year, the Virginia Tech (VT) Formula SAE (FSAE) team creates a high performance car to compete against 120 teams from around the world in a series of dynamic events evaluating acceleration, maneuverability, and handling. In an effort to improve upon the VT 2013 car, the torsional stiffness of the chassis was increased. Increasing the torsional stiffness of the chassis allows the suspension to be more precisely tuned, resulting in a better overall performance. An investigation was conducted into methods for improving the chassis stiffness, and it was determined that many state-of-the-art vehicles from go-karts to super cars incorporate strength-bearing, tailored advanced composite materials in their structure. Examples of components that use composites in vehicles include sandwich structures in load-bearing panels, layups in the skin of vehicles for aesthetic purposes and carbon-fiber frame tubes. The VT FSAE car already includes untailored carbon-fiber panels on the bottom and sides of the structure for packaging and aerodynamic purposes. By integrating and optimizing these carbon-fiber panels, the torsional stiffness and therefore overall performance of the structure may be increased. This thesis explores composite testing, optimization methods, experimental and computational analysis of the chassis, and results. The fiber orientation of the panels may be optimized because carbon-fiber composite materials are generally anisotropic. Therefore the composite materials can be tailored to maximize the stiffness, resulting in the optimum stiffness per added weight. A good measure for testing stiffness per added weight is through measuring natural frequencies because natural frequency is proportional to stiffness per unit mass. A computer program was developed in MATLAB to optimize the composite configuration, and uses an objective function involving the first three natural frequencies of the original steel space frame chassis and the first three natural frequencies of the steel chassis augmented with three composite panels. The composite material properties were determined using specimen tensile testing and checked with finite elements. The natural frequencies of the half-scale chassis were determined experimentally, compared to the simulated version, and varied by less than seven percent. The optimization of the full-scale model determined that eight layers of optimized, integrated carbon-fiber composite panels will increase the first, second, and third natural frequencies by sixteen, twenty-six, and six percent, respectively. Natural frequency increases of these amounts show that by using tailored, load-bearing composite panels in the structure, the torsional stiffness of the structure increases, resulting in easier suspension tuning and better performance at the VT FSAE competitions.

Abstract:

A racing vehicle suspension system is a kinematic linkage that supports the vehicle under complex loading scenarios. The suspension also defines the handling characteristics of the vehicle. Understanding the loads that the suspension carries in a variety of loading scenarios is necessary in order to properly design a safe and effective suspension system. In the past, the Formula SAE team at Virginia Tech has used simplified calculations to determine the loads expected in the suspension members. This approach involves several large assumptions. These assumptions have been used for years and the justification for them has been lost.

The goal of this research is to determine the validity of each of the assumptions made in the method used for calculating the vehicle suspension loads by hand. These assumptions include modeling the suspension as pinned-pinned truss members to prevent bending, neglecting any steering angle input to the suspension, and neglecting vertical articulation of the system. This thesis presents an approach to modeling the suspension member loads by creating a finite element (FE) model of the entire suspension system. The first stage of this research covers the validation of the current calculation methods. The FE model will replicate the suspension with all of the current assumptions and the member loads will be compared to the hand calculations. This truss-element-based FE model resulted in member loads identical to the hand calculations.

The next stage of the FE model development converts the truss model to beam elements. This step is performed to determine if the assumption that bending loads are insignificant is a valid approach to calculating member loads. In addition to changing the elements used from truss to beam element, the suspension linkage was adapted to more accurately model the methods by which each member is attached to the others. This involves welding the members of each control arm together at the outboard point as well as creating a simplified version of the pull rod mounting bracket on the upper control arm. The pull rod is the member that connects the ride spring, damper, and anti-roll bar to the wheel assembly and had previously been mounted on the upright. This model reveals reduced axial components of load but increases in bending moments sizable enough to reduce the resistance to buckling of any member in compression.

The third stage of model development incorporates the steer angle that must be present in loading scenarios that involve some level of cornering. An analysis of the vehicle trajectory that includes the effects of slip angle is presented and used to determine the most likely steer angle the vehicle will experience under cornering. The FE model was adapted to include the movement of the steering linkage caused by driver input. This movement changes the angle of the upright and steering linkage as well as the angle at which wheel loads are applied to the suspension. This model results in a dramatic change in member loads for loading cases that involve a component of steering input. Finally, the FE model was further enhanced to account for vertical movement of the suspension as allowed by the spring and damper assembly. The quasi-static loading scenarios are used to determine any member loading change due to vertical movement. The FE model is also used to predict the amount of vertical movement expected at the wheel center. This data can be used by the suspension designer to determine if changes to the spring rate or anti-roll bar stiffness will result in a more desirable amount of wheel movement for a given loading condition. This model shows that there is no change in the member loads due to the vertical movement of the wheel.

This thesis concludes by presenting the most important changes that must occur in member load calculations to determine the proper suspension loading under a variety of loading scenarios. Finally, a discussion of future research is offered including the importance of each area in determining suspension loads and recommendations on how to perform this research.

Abstract:

The Formula SAE Electric competition is a collegiate autocross event in which teams design, build, and race an open-wheeled electric race car. The main motivation is the efficiency advantage of electric motors over internal combustion motors. This thesis presents the design and evaluation of two generations of Portland State University electric race cars.

The constraints are the competition rules, finances, human resources, and time required to complete a race car in one year. The design includes the implementation of existing components: battery cells, controllers, electric motors, drivetrains, and tire data for an optimized race car. Also, several circuits were designed and built to meet the rules, including the shutdown, precharge, discharge, brake system plausibility, tractive system active light, and an electric vehicle control unit.

The car’s performance was modeled with calculations and OptimumLap simulation software, then track tested for actual data. Performance data such as torque, power, and temperatures were logged, and the Formula SAE events were tested. The data were compared to the simulations and records from past competitions, and the car was 21% to 30% behind the best times.

The motor generated 410 Nm of peak torque, as expected, but the maximum power was 51 kW, 15% less than the calculated 60 kW. Compared to the best times of past competitions, the car completed Skid-pad in 6.85 seconds (21% slower), and Acceleration in 5.65 seconds (25% slower). The first generation car was tested for range, and raced 31.4 km on a cold, wet track, so tire forces were decreased 6% to 69% from a dry track. During the 22 km Endurance test with the second generation car, there were problems with imbalanced cell voltages, limiting the test to 4.9 km. Later, there was a catastrophic drivetrain failure, and Endurance testing on a dry track was not completed.

In dynamic event simulations, a lighter, axial flux permanent magnet synchronous motor with a decreased counter EMF yielded improved times. Reconfiguring the battery pack from 200 V_DC 300 V_DC would provide 50% more peak power. Further testing is required to determine the actual average power use and making design decisions with an improved battery pack.

Abstract:

The Hashin failure criteria and damage evolution model for laminated fiber reinforced polymers are explored. A series of tensile coupon finite element analyses are run to characterize the variables in the physical model as well as modeling techniques for using an explicit dynamic solver for a quasi-static problem. An attempt to validate the model on an axial tube crush is presented. It was found that fiber buckling was not occurring at the impactor-tube interface. Results and speculation as to why the failure initiation is incorrect are discussed. Lessons learned from the tube crush are applied successfully to the quasi-static Formula SAE nosecone crush test. The model is validated by experimental data and the impact metrics between the test and model are within 5%. Future work and possible optimization techniques are discussed.

Abstract:

L’obiettivo di questa tesi è illustrare quali siano stati i metodi di studio e le soluzioni adottate per ottimizzare gli impianti di raffreddamento e lubrificazione della monoposto da competizione sviluppata dal team Unibo Motorsport, in preparazione alla stagione di gara 2016 della Formula SAE®. Inizialmente saranno analizzate le principali problematiche di entrambi gli impianti attraverso simulazioni CFD (Computational Fluid Dynamics) e dati telemetrici degli anni passati. In seguito, saranno mostrati i diversi procedimenti di progettazione e il completamento degli impianti unitamente ad una loro valutazione economica. Infine, per verificare l’effettivo successo delle operazioni svolte a bordo vettura, verranno mostrate acquisizioni telemetriche relative alle gare ed altre simulazioni relative alle nuove geometrie sviluppate. Un altro obiettivo della trattazione è mettere a disposizione dei futuri membri del reparto motore un documento che contenga tutte le considerazioni fatte a riguardo degli impianti studiati. Questo è fondamentale all’interno di un ambiente come un team di Formula SAE®, dove ogni anno si ha il ricambio di una buona parte dei membri. Se gli studi svolti sugli impianti venissero persi, i nuovi arrivati si troverebbero a mettere le mani su un qualcosa di sconosciuto e lo sviluppo della vettura negli anni si troverebbe enormemente rallentato. Il “learning by doing” che ha sempre caratterizzato questo progetto viene infatti affiancato con armonia dalla possibilità di consultare esperienze pregresse relative al caso di studio considerato.

Nel presente elaborato si è illustrata l’implementazione di un modello numerico multibody atto allo studio della dinamica laterale di un veicolo da Formula SAE. Vista la vastità degli argomenti trattati, la tesi non ha la pretesa di esaurire tutte le tematiche legate alla realizzazione di un modello veicolo, ma vuole comunque evidenziare quelle che sono state le scelte e le valutazioni alla base del lavoro svolto. Il punto di partenza è stata la caratterizzazione dello pneumatico. Questa fase è di fondamentale importanza in quanto un accurato modello gomma è la base su cui sviluppare un modello che sia affidabile ed in grado di esprimere le potenzialità e le criticità della vettura che rappresenta. Successivamente si sono implementati tutti gli altri sistemi meccanici costituenti il veicolo, riservando particolare attenzione alle sospensioni e al differenziale autobloccante. Completato l’assieme, il passo successivo è stato quello di individuare ed eseguire le simulazioni necessarie alla validazione mediante il confronto con i dati sperimentali. Verificato che il modello rispondesse in maniere coerente con quanto letto dalle variabili misurate in vettura, se ne sono mostrate le potenzialità mediante la realizzazione del diagramma di sottosterzo e dello Yaw Moment Diagram per diversi setup del veicolo.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2006.
Includes bibliographical references (leaf 34).
A dry sump lubrication system for a Formula SAE race car was designed and manufactured in order to gain the various advantages this type of system affords. A dry sump system stores oil in an external tank and pumps it between the engine and tank as needed. This allows for a shallower oil pan, which permits lower engine placement. This lower placement improves handling through a lower center of gravity. Additionally, the highly stressed racing engine, a Honda CBR 600 F4i, receives more constant lubrication than a conventional wet sump system. The system included design of a new pan, tank and the associated bracketry and hoses that are needed to make the system functional. The design of the system stressed reliability while keeping an eye on weight to minimize it whenever possible. Detailed analysis and the methodology driving the design choices are presented here along with simple dry sump theory. This document serves as the roadmap through the design of the first dry sump system on an MIT FSAE car. It should prove beneficial to the team when the official design report is created for the competition. Lastly, it will help assist future members who certainly aim to refine the package in subsequent years to make it smaller, cheaper, lighter, more reliable and simply better performing overall.

Abstract:

Finite element is used to predict the torsional stiffness and natural frequency response of a FSAE vehicle hybrid chassis, utilizing a carbon fiber reinforced polymer sandwich structure monocoque and a tubular steel spaceframe. To accurately model the stiffness response of the sandwich structure, a series of material tests for different fiber types has been performed and the material properties have been validated by modeling a simple three-point-bend test panel and comparing the results with a physical test. The torsional stiffness model of the chassis was validated with a physical test, too. The stiffness prediction matches the test results within 6%. The model was then used to model the natural frequency response by adding and adjusting the materials’ densities in order to match physical mass properties. A hypothesis is made to explain the failure of the engine mounts under the dynamic response of the frame.

Abstract:

Aerodynamic devices, such as wings, are used in higher levels of motorsport (Formula-1 etc.) to increase the contact force between the road and tyres (i.e. to generate downforce). This in turn increases the performance envelope of the race car. However the extra downforce increases aerodynamic drag which (apart from when braking) is generally detrimental to lap-times. The drag acts to slow the vehicle, and hinders the effect of available drive power and reduces fuel economy. Wings, in automotive use, are not constrained by the same parameters as aircraft, and thus higher angles of attack can be safely reached, although at a higher cost in drag. Variable geometry aerodynamic devices have been used in many forms of motorsport in the past offering the ability to change the relative values of downforce and drag. These have invariably been banned, generally due to safety reasons. The use of active aerodynamics is currently legal in both Formula SAE (engineering compet ition for university students to design, build and race an open-wheel race car) and production vehicles. A number of passenger car companies are beginning to incorporate active aerodynamic devices in their designs. In this research the effect of ground proximity on the lift, drag and moment coefficients of inverted, two-dimensional aerofoils was investigated. The purpose of the study was to examine the effect ground proximity on aerofoils post stall, in an effort to evaluate the use of active aerodynamics to increase the performance of a race car. The aerofoils were tested at angles of attack ranging from 0° - 135°. The tests were performed at a Reynolds number of 2.16 x 105 based on chord length. Forces were calculated via the use of pressure taps along the centreline of the aerofoils. The RMIT Industrial Wind Tunnel (IWT) was used for the testing. Normally 3m wide and 2m high, an extra contraction was installed and the section was reduced to form a width of 295mm. The wing was mounted between walls to simulate 2-D flow. The IWT was chosen as it would allow enough height to reduce blockage effect caused by the aerofoils when at high angles of incidence. The walls of the tunnel were pressure tapped to allow monitoring of the pressure gradient along the tunnel. The results show a delay in the stall of the aerofoils tested with reduced ground clearance. Two of the aerofoils tested showed a decrease in Cl with decreasing ground clearance; the third showed an increase. The Cd of the aerofoils post-stall decreased with reduced ground clearance. Decreasing ground clearance was found to reduce pitch moment variation of the aerofoils with varied angle of attack. The results were used in a simulation of a typical Formula SAE race car.

Abstract:

The advent of finite element methods has changed the tire industry's design process over the past three decades. Analyses, previously impractical using analytical methods and physically limited by experimental methods, can now be performed using computational methods. This decreases the cost and time associated with bringing a new design to the marketplace; however some physical testing is still required to validate the models. The design, fabrication, installation, and operation of a tire, suspension, and chassis test fixture (TiSCTeF) is detailed as part of this study. This fixture will support the validation of effective, parametric finite element models currently under development, as well as the design and testing of suspension and chassis components for the Virginia Tech Formula SAE team. The fixture is designed to use the Formula SAE race car as the test platform. Initially, the fixture is capable of performing static load-deflection and free-rolling tire tests. Provision has been made in the design for incremental upgrades to support cornering tests and additional instrumentation. An initial load-deflection test has proven that the fixture is capable of creating reproducible data sets. Specific recommendations are made concerning the improvement of data quality for future tests. This study also presents a process for analyzing existing tire cornering data and eliminating anomalies to improve the effectiveness of normalization techniques found in the literature. The process is shown to collapse tire cornering data, which is partially ill- conditioned, onto master curves that consistently display the effect of inclination angle and tire inflation pressure on tire response.

Abstract:

Dal 2010 al 2012 ho fatto parte del team UniBo Motorsport, che partecipa alle competizioni di Formula SAE, una categoria di vetture monoposto a ruote scoperte con cilindrata fino a 610cm^3, interamente progettate e costruite da studenti universitari, valutati non solo per le prestazioni dinamiche della vettura ma anche su prove statiche legate agli aspetti progettuali, economici e gestionali. Nel team ho curato i servizi IT e le prove statiche "Presentation Event", una simulazione di business plan per una nuova impresa automotive legata al prototipo, e "Cost & Manufacturing Analysis Event", un'analisi dei costi e della produzione attraverso una distinta base di produzione della vettura. In particolare nel 2012 sono stato responsabile della distinta base, introducendo importanti strumenti ed ottimizzazioni per semplificare la redazione ed ottenere migliori risultati. Nel 2013 ho fornito consulenza ai membri del team che ora seguono il lavoro. A partire da questa esperienza ho deciso di sviluppare la tesi sul tema della gestione della distinta base di produzione, spiegando nel dettaglio i cambiamenti apportati, le motivazioni e i risultati ottenuti. Prendo inoltre in esame alcuni componenti meccanici della vettura, sia per esemplificare la redazione della distinta base, che per alcuni aspetti interessanti di questi componenti: le ruote foniche, per cui sono disponibili molti dettagli sulle fasi di produzione, i rocker delle sospensioni e la corona monoblocco, di cui è stata considerata la produzione da parte di fornitori asiatici oltre che locali con vari preventivi disponibili per il confronto dei diversi mercati.
