Abstract:

Reverse design and forward design have their strong points each other. The advantages of reverse design lie in the treatment of free-form complex modeling, while forward design is good in modeling in simpler feature. The car body often contains complex curved surface and some simple features. Through a single reverse or forward design can’t realize the efficient design. In order to combine advantages of reverse and forward design, using the hybrid design process design can improve the efficiency of the development of car body.

Abstract:

This paper is concerned with an optimization design for the solar car body under a single load is carried out by using finite element optimization design (FEOD) model. Topology optimization and sizing optimization are explored to find out an optimal manufacturing feasible design from multiple optimized designs of material reinforcement of the solar car body for rigidity improvement. The application of these methods demonstrates that through innovative utilization of the topology optimization technique, an optimal manufacturing feasible design can be obtained. The relationship between the rigidity improvement and different configuration of material reinforcement is also investigated. It is concluded that through appropriate application of FEOD methods, the overall rigidity of the solar car body framework can be improved substantially in a cost effective manner and provides more convincing evidence for optimization design of the solar car body. The results demonstrate that the optimized solar car body is safer and lighter.

Abstract:

The Energy Saving Car Contest (KMHE) is a contest organized by the Ministry of Research, Technology and Higher Education (Kemenristekdikti). This is a contest among students to make a national level fuel efficient vehicle. The purpose of designing this design is to produce an energy-efficient car body design "Mataram Proto" and to produce a vehicle that has a good aerodynamic level. This design of the car body is designed elegantly but still has good aerodynamics and does not reduce the safety aspects of the driver. The process of making a car body design uses Autodesk Inventor and the process of aerodynamic analysis of the Mataram Proto car body uses Ansys Mechanical software. Aerodynamic testing was carried out at an air speed of 45 km / h or 12.5 m / s. From the previous Mataram Proto body test results, the drag coefficient was 0.233 and the lift coefficient was 0.1887 and from the Mataram Proto V5 car body test, the drag coefficient was 0.47 and the lift coefficient was 9.95. From the results of this test, it shows that the previous Mataram Proto car body had a better aerodynamic level due to the difference in the input of different airspeed variables, where the air velocity on the previous Mataram Proto car body was 40 (km / h) and the air speed on the Mataram Proto V5 body. amounting to 45 (km / hour).

Abstract:

In this paper, ANSYS software is applied to determine the material distribution, load transfer path and equivalent sectional dimensions of the conceptual car body model based on the original body shape of engine cars. In terms of the finite element model of the body, the topology optimization is carried out according to the maximum bending and torsion stiffness, respectively. Through comparing the material distribution under different volume fractions and considering at the same time the manufacture feasibility, the initial style of body frame is achieved. Then, as the sectional dimensions of beams is optimized in both size and dimension, parameter matching scheme of the body frame in minimized weight is brought forward under constraints of the strength and stiffness at maximum frontal impact loads that improves the utilization rate of the material. The results suggest that both the design efficiency and quality can be improved greatly by combining topology and size optimization technology at the concept design phase of car body structure.

Abstract:

One of many solutions that can be applied to solve the transportation problems in Yogyakarta is by adding another mass transportation system which is eco friendly, ergonomic, and does not cause congestion and accident in the highway. There are several kinds of mass transportation that can be developed in Yogyakarta, such as monorail, tram, even commmuter line. But considered from the various advantages and disadvantages, the monorail is an additional mode of transport that is most suitable for Yogyakarta, because its railways are not become one with the road like a tram that may caused another negative impact. The main orientation of this design is to make a monorail body carriage. In designing this monorail body carriage, the conditions of design follows the model and carriage capacity that applied by urbanout with the operating condition data including the size of the carriages, passenger capacity, speed of the train, and the wheel base distance. Aluminum alloy 6061 material is used in the design of the carriage frame. And then the forces working on the carriage is calculated. The magnitude of the forces working on the carriage must be able to be endured by the frame. Data from the design then simulated with static load simulation using Autodesk Inventor 2012 software. From the analysis results will be seen whether the design of the carriage frame structure has been made safe. The size of the carriage is 8800mm x 2350mm x 3100mm for the front and rear car and 6700mm x 2350mm x 3100mm for the middle car. The results showed that the structure of the carriage from urbanout model with frame made of aluminum alloy 6061 is strong enough and suitable for use in light monorail vehicle. With the smallest safety factor by 4.56.

Tub-type car is a kind of truck which increases the usage of the rolling stock clearance. Its special tub-shaped structure provides more space for cargo that increases the load utilization factor. The analysis of the structural strain strength proves that the design and material of the tub-type car body fit the actual demand according to the rules of the <AAR Specification>. The stress of every point everywhere on the structure of the car body is below the yield stress which ensures the safety of the car body during the operation. The simulation results reflect the stress distribution of the whole car body which provides the reference for design and test.

Abstract:

White body in the design process needs to meet the needs of a wide range of performance requirement. Adequate stiffness and modal are the basis to ensure the vehicle’s performance of vibration noise. Simultaneously, in order to reduce energy consumption and cost, the lightweight design of the white body has become the mainstream. In this paper, the optimization design is conducted for stiffness and modal of a commercial vehicle’s white body based on the theory of the finite element size sensitivity optimization design. Firstly, build the finite element model of a vehicle’s white body and analyze its stiffness and modal. Some changes were made to the car-body’s partial structure according to the distributing of strain energy achieved from above analysis, which improved the car-body’s dynamic and static performance initially. Secondly, choose panels needed to be optimized by reference to the density of strain energy and panels’ mass. Then, the car-body’s structure was optimized using panels’ thickness as design variables, stiffness and modal frequencies as constrains and minimizing weight of white car-body as objective. After the analysis of the result, modal separation was put forward to improve the quality of this finite element optimization design model. Finally, the car-body’s stiffness and mode nature entirely satisfied the requirements with car-body’s weight decreased.

Abstract:

The design optimisation of car seats is vital in ensuring comfort and safety whilst driving. The main aim of this study is to determine the relationship between anthropometric parameters, interface pressure on car seats and driver’s safety in a preferred driving position. A pressure-map sensor was used to identify the pressure patterns on the car seat. Results indicate significant relationships were found between interface pressure of car seat and certain anthropometrics dimension. A strong correlation was established amongst body mass, body mass index and interface pressure at certain body parts, with r of nearly 0.50. Majority of the anthropometric dimensions and interface pressure show medium correlations between 0.31 and 0.49. The established relationship helps to estimate the perceived comfort and safety related to the car seat design. Hence, this guideline can help to prevent driver’s fatigue by considering the elements of anthropometrics and interface pressure in the car seat design.

Abstract:

A city car is needed to overcome congestion and parking spaces in urban areas. However, currently, the body design of the city car is still experiencing problems, namely the value of the large drag coefficient, which causes an increase in fuel consumption. This study aims to design a city car body with two passengers that is more aerodynamic so as to minimize fuel use. This research method is a numerical simulation model using the ANSYS fluent students version 2021. Parameters in the form of drag coefficient values, velocity streamlines and velocity contours on the city car are aerodynamic aspects that are analyzed. The results show that the dimensions of the designed city car have a length of 2.59 m, a width of 1.6 m, and a height of 1.52 m by considering the ergonomic parameters and comfort of the user so that it fits the character of the people in Indonesia. In addition, from the independence grid analysis performed, the value of the number of meshes that have the smallest error value is obtained, namely mesh C (the number of meshes is 129,635). Mesh C has an error of 7.2%. It was found that as the velocity increases, the value of the drag coefficient (CD) produced is relatively smaller. In a city car with a velocity of 10 m/s, the drag coefficient value is 0.599, at a velocity of 20 m/s, the drag coefficient value is 0.594, and a velocity of 30 m/s is a drag coefficient value of 0.591.

Abstract:

In view of the problem that special gondola cars are generally insufficient for the actual transportation of coke, and in order to improve the transportation efficiency and reduce the transportation cost, the 80 t depressed-center gondola car for coke transportation is designed by the anti-fatigue design method in this paper. The car body with a supporting bar and the car body without a supporting bar are simulated and analyzed by the finite element method; the results show that there are stress mutations at the transition area of the two key welds, especially at the 110 mm of weld 1. The fatigue lives of the two car body schemes are evaluated by Miner linear cumulative damage theory, spectrum and S-N curve in AAR standard, and load spectrum of the Daqin line and S-N curve in BSI standard. The results show that the 80 t depressed-center gondola car body with a supporting bar is the best scheme. In addition, the fatigue damage results show that the vertical load spectrum of AAR is worse than that of the Daqin line, and the longitudinal load spectrum of the Daqin line is worse than that of AAR. This conclusion will provide a basis for an anti-fatigue design of heavy haul wagon bodies or bogies.

Abstract:

The estimation of production rate (or throughput) is important in manufacturing system design. Herein, we consider the manufacturing system of an automotive body shop in which two types of car are produced, and one car (engine car) is substituted by the other car (electric car) gradually. In this body shop, two different underbody lines are installed because the underbody structures of the two types of cars differ completely; however, the side body line and main body line are shared by the two cars. Furthermore, we assume that the underbody lines are reconfigurable based on an increase in the product mix of the electric car. A simulation-based meta-model, which is in the form of a quadratic polynomial function, is developed to estimate the production rate. In the meta-modelling process, we group some buffer locations and represent them as one variable to reduce the number of variables included in the meta-model. Subsequently, the meta-models have been used to optimize two types of buffer allocation problems, and optimal solutions are obtained easily.

Abstract The subject of this publication is a rally car designed as a diploma thesis and later produced. G-Sport Ltd. designs and manufactures racing car bodies, chassis components and all other motorsport related components for both the domestic and international markets. The aim was to design the Lada 2106 race car to accept a Ford Mk2 suspension, a Toyota 4A-GE engine and other parts that would enable it to compete in official FIA rally events. The work was done using a 3D scanner. The first phase involved creating 3D models of the body, engine, gearbox and other components, while checking their dimensional accuracy. Then, the custom parts of the car, including the roll cage, had to be designed to meet FIA specifications. This article describes the steps of the 3D scanning method, how the scans are processed, oriented, assembled correctly, and how the deformations of the body frame were detected. In addition, the typical problems encountered during 3D scanning of large objects and their generally applicable solutions are shown. The components of the drivetrain and components of own custom design are also described.

Abstract:

This paper develops a novel approach for the lightweight design of a car body frame. In this approach, the cross-sectional dimensions of a car body frame are treated as design variables. First, sampling points are created based on Latin Hypercube Sampling (LHS), and then Design of Experiment (DOE) is conducted. After that, an analysis is done to obtain those design variables affect the results most. Finally, Sequential Quadratic Programming (SQP) is utilized to solve the optimization problem while the amount of design variables is reduced according to the former analysis. The advantage of this method is that it reduces the burden of optimization algorithms and offers a practical way for the lightweight design of a car body frame.

Abstract:

As a method of investigations there is adopted a computer mathematical modeling based on the use of a finite element method. The choice of a type and perforation parameters is connected with the problem in the large array creation of bearing structure design models of passenger car bodies. The analysis of investigations carried out in the field of multi-variation computations has shown that the most efficient investigation method is a superelement reduction. Its use allows decreasing labor and time costs for the body design model development at the expense of the initial super-element with the perforation area for a new one. The appraisal of the procedure offered on the choice of a body efficient bearing structure with the perforated profiles is carried out by the example of the body of a domestic passenger car according to the criteria of strength and assurance of the highest weight reduction of a bearing structure. In the first stage of the work there are defined types and parameters of perforation possible for use in the structure. Finite element design models of car bodies are developed. On the basis of strength computation results the reinforcing elements of the structure are offered which have a margin safety for perforation application in them. Based on the analysis of car body bearing structure there is carried out a choice of an efficient unit of a finite element model which will be used as a super-element. In the next stage of the work there are developed and computed structures of car bodies with the perforation types under consideration and with the use of superelements. The computation results have shown that maximum design stresses of car bodies for all perforation types under consideration do not exceed legitimate values. As an efficient bearing structure of a passenger car body there is adopted a car body with the sixth type of perforation ensuring the largest decrease of structure metal intensity and satisfying strength requirements. The procedure developed can be used at designing modern bearing structures of passenger car bodies having improved technical and economic values.

Abstract:

with the speed rising of railway train and the weight lightening of car-body, the frequency range of car-body is widened and the natural frequency is decreased. Especially, the local modes of car-body are caused by suspension device under the car-body bottom, which lead to large vibration response, influence the ride comfort and fatigue failure of structure. In this paper, the whole mode of car-body was analyzed through finite element software. The local mode of car-body bottom and side wall were computed by method of equivalent stiffness constrain. The results show that the local mode of car-body is mainly caused by asymmetry suspension device. The modal analysis method and local modal analysis method adopted in this essay provide the reference and guide the dynamic structural design.

Abstract:

One of the developments in automotive technology is identified by the increasing variety of vehicle products in the market. This development also leads to the refinement of the design of a more aerodynamic car shape to reduce air friction which can reduce material consumption. Because in theory, the aerodynamic shape of the vehicle's body can reduce fuel consumption and minimize the forces that hinder the vehicle's speed. The purpose of this study is to design a more aerodynamic car body, determine the air flow pattern around the car, and simulating the design of the car body to determine the amount of drag coefficient, using Spoiler and without spoiler E-Falco Car Body with variations in speed of 10 km/h, 20 km/h and 40 km/h. The results of this study indicate that the greater the driving speed, the greater the drag generated. The average drag coefficient for the 3 speed variations is 1,995 for design I and 1,905 for design II. The smallest drag coefficient with a value of 1.887 occurs in Design II with a speed used of 40 km/hour and the largest value of the coefficient of drag with a value of 2.043 occurs in Design I with a used speed of 10 km/hour. Design model II is more aerodynamic than design I, the smallest drag coefficient is 1.887. So that the body for the KMLI 2020 competition is recommended to use the design model II which use Spoiler.

Abstract:

Cross-sectional shapes and dimensions of concrete guardrails directly influence climbing angles and directions of a car when a collision between concrete guardrail and car occurs. At the same time, contacting and climbing angles and directions influence the peak crushing force and the peak acceleration of a car body during a collision. Therefore, cross-sectional shapes and dimensions of concrete guardrails can influence the severity of injuries sustained when a collision between concrete guardrail and car occurs. In this study, the passive safety of a car body is considered in optimizing the cross-sectional dimensions of a New Jersey (NJ) concrete guardrail based on numerical simulations and surrogate model techniques. Optimal Latin hypercube design is used to get sampling points, and multi-island genetic algorithm is utilized to obtain the optimal size of NJ concrete guardrail in the optimization process. After simulating the collision between car and optimal NJ shaped guardrail, the results show that the peak acceleration of optimal results reduces significantly by 28% compared with the initial value, and the peak interface force decreases from 378.6 kN to 241.5 kN.

Abstract:

A passenger railway vehicle’s lightweight design is an efficient technique of reducing energy consumption and dynamic forces between wheel and rail. However, light design results in resonant vibration in a car body. To restrain resonant vibration, a correlation between the suspended equipment variables and the car body’s modal frequency was investigated in this paper. A rigid–flexible general model was developed to examine the impacts of different equipment suspended under the chassis based on mass, location, and frequency on the car body mode. In addition, the numerical model is validated through the experimental result in terms of ride quality. The results demonstrate that the underframe equipment’s suspension characteristics have a significant impact on the mode of the car body, particularly the frequency of the first bending mode. Equipment with a considerable mass should be suspended near the center of the car body to optimize the frequency of the car body’s high-frequency bending. The weight of the equipment has a significant impact on the car body’s first bending frequency. The frequency of heavy equipment should be low enough to promote high-frequency transmissibility and improve the vibration characteristics of the car body.

Abstract:

The use of modern means of mechanization of loading and unloading operations in places of mass processing of bulky loads in railway and water connection allows to increase the efficiency and productivity of various types of transport, to ensure the safety of load and rolling stock. The most common method of unloading open wagons in ports, mining enterprises, thermal power plants, etc. is the use of special rotary car dumpers. However, it should be noted that unloading on the car dumpers leads to damage of the carriages structural elements. The article presents the results of strength calculations of the car dumper body under the influence of specified dynamic loads from the expiring cargo. They show that the safety margin of the load-bearing elements of the car body is not enough at critical corners of rotation of the car dumper rotor. The studies were carried out using modern computer modeling methods used in the development of new-generation freight car designs. The software package took into account the effects of dynamic loading as external factors that occur at different corners of the car dumper rotor. The implementation of the results obtained at the design stage of innovative structures of open wagon car bodies will allow predicting the operational parameters of load-bearing structures. The presented studies are aimed at improving the safety and operational reliability of the cargo car fleet.

Abstract:

In this paper, a new parameterized surface, termed SQ-Coons surface, is proposed according to the build mode of Coons patch. The surface is always interpolated to the boundary curves, and its shape details could be controlled by the shape parameters in CE-Bézier basis functions, which makes it suitable for styling design in computer aided design (CAD). In order to exert its geometric advantages in car design, a simplified body CAD template based on characteristic lines is built according to common vehicle features. The template is built entirely from SQ-Coons surfaces, so that the overall style and detail shapes could all be modified by the control points and shape parameters of each surface. By analyzing the curvature of fifty commercial car types generated through the template and various parameters, a set of methods for constraining the range of shape parameters is proposed. On this basis, as an example, the four shape parameters of the hood surface in one model are used as variables to optimize the body shape to achieve the lowest possible aerodynamic drag coefficient in computational fluid dynamics (CFD). The results show that the design method, combining the new surface and the model template, could reflect the modeling characteristics of different cars, and improve the design and scheme adjustment efficiency in the conceptual design stage.

Abstract:

Box girder is an important bearing and force transmitting component in the gondola car body; the rationality of its structure directly affects the life of the whole car body. In order to solve disadvantage of the traditional box girder optimization method, which mainly depends on design experience, the combined method of orthogonal experimental design and the genetic algorithm-back propagation (GA-BP) algorithm is used for the structural optimization of bolster beam in this paper. Nine groups of parameters were established by orthogonal experiment, which can give typical samples for GA-BP optimization. Then, the bolster beam is optimized by the GA-BP algorithm, and the new gondola car body model is established with the optimized parameters. The finite element analysis results show that the minimum stress is found by using the GA-BP algorithm, which is basically consistent with the simulation results. Finally, the results show that the combined method of orthogonal experimental design and GA-BP algorithm is feasible to the box girder optimization of the gondola car body. Meanwhile, the optimization results of bolster beam will provide a reference for the structural design of the heavy haul wagon body.
