Composite materials are used for products needing high strength-to-weight ratios and good corrosion resistance. For these materials, various composite manufacturing processes have been developed such as Automated Tow Placement, Braiding, Diaphragm Forming, Resin Transfer Molding, Pultrusion, Autoclave Curing and Hand Lay Up. The aim of this paper is to examine the equipment used for these seven processes and to produce a cost analysis for each of the processes equipment. Since many of these processes are relatively new or are fairly costly and specified to the customers need, much of the equipment is custom made to meet the requirements of the part being produced. Current pricing information for individual custom-built machines, as well as standard machinery has been provided here.

Capital equipment is a critical component of almost every industry and is used to create valuable goods and services for the end customers. However, the initial cost of acquisition and subsequent running costs associated with these equipment pose a significant barrier to young businesses. While servitizing capital equipment is a proven method of increasing access to these machineries in many high-income countries (HICs), the benefits of servitization often do not extend to low- and middle-income countries (LMICs). In this thesis, I examine the capital equipment ecosystems of both HICs and LMICs, with a focus on the stakeholders involved. I also explore both the challenges facing equipment businesses when operating in LMICs and the innovative solutions being implemented by successful LMIC service businesses. Based on these examples, I offer recommendations for budding service-based equipment business that are working to improve affordable access to capital equipment in resource-constrained settings.

Повний текст джерелаThe set theoretical approach was applied to the development of a diagnostic decision support system for a semi-automated Atlas Copco Wagner ST-8B Load-Haul-Dump vehicle. Hypothesis sets were generated for the vehicle's hydraulic circuit and Deutz FL-413-FW diesel engine. A high level of diagnostic resolution was achieved for the hydraulic circuit, but limited resolution was achieved for the diesel engine. This was postulated to be due to the ratio of observable system outputs to input sub-systems, and the number of least repairable units making up each system.
Manual knowledge acquisition was undertaken in an underground mine to refine the diagnostic knowledge developed from the hypothesis sets and to add knowledge to discriminate between competing failure hypotheses. Heuristic failure likelihoods were used to rank hypotheses in order of frequency of occurrence. The knowledge base was implemented as a hypertext decision support system using HyperText Mark-up Language (HTML). The resulting decision support system is platform independent, upgradeable and able to be maintained by site personnel. The system is currently installed at surface level and at 1800 level at INCO Limited's Stobie Mine in Sudbury, Ontario.
The thesis makes a number of original contributions, the first two of which are of generic significance. It is the first work to apply set theoretical concepts to structural models of mobile mining equipment in order to diagnose faults. A number of modifications are advanced to the conventional trace-back analysis technique for generating contributor and normality sets, and heuristic guidelines are provided for estimating the costs and benefits of developing, implementing and maintaining diagnostic decision support systems. It is also the first work to formalise a decision support system in HTML and to suggest the application of company-wide internets ("intranets") to disseminate maintenance knowledge within mines.
Tjernberg, Anders. "Fatigue assessments of components in construction equipment." Doctoral thesis, KTH, Aeronautical Engineering, 2001. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-3117.
Повний текст джерелаThe thesis refers to "Fatigue Assessment of Components inConstruction Equipment". The subject was chosen because ofincreasing interest in higher payloads, lower weight, highervelocities and shorter load cycles in construction equipmentvehicles.
The main research goal in this thesis is to investigatetechniques to extend the fatigue life of an induction hardeneddrive shaft, with splines. Areas related to this research areresidual stress, fatigue life assessments, manufacturingprocess parameters and hardening process parameters. Themethods used to achieve the goal are process simulations,fatigue tests, finite element calculations, measurements ofresidual stress and fatigue life assessments. The aim of thepresent research is to cover several aspects of applied fatigueassessment. Most of the theoretical work has been verified withmeasurements and fatigue tests.
The residual stresses have been calculated by simulating thehardening process with SYSWELD, a Finite Element program. Thesimulated residual stress beneath the surface was compared toX-ray and neutron diffraction measurements. The conformancewith simulations and X-ray measurements was relatively good,but the conformance with neutron diffraction measurements wasnot so good. The detrimental axial tensile residual stress atthe core was found to be in the order of 800-900 MPa, for theshafts.
About 100 shafts have been fatigue tested in torsion, bothin constant amplitude and in variable amplitude and some of theresults have been reported in this thesis. For many of theshafts, crack initiation beneath the hardening layer wasdetected, which depends on the high tensile residual stress inthe core. Fatigue life assessments were made on the shafts,using a multiaxial strain based critical plane model, with themeasured residual stresses as input data. The generalconclusion is that the induction hardening process parametersinfluence the residual stresses to a high extent and thusinfluence fatigue life. Simulations of how different hardeningprocess parameters influence the residual stress profile havebeen done. Low hardening power and low frequency seem to reducethe detrimental tensile residual stress at the core.
The load distribution along the axis of the spline teeth hasbeen investigated. The shear stress concentration in a splinehas been calculated by the finite element method, using anon-linear model, and was compared with results found in theliterature. An equation describing how the tooth thicknessshould vary to obtain smooth contact in the axial direction hasbeen derived. Finally, fatigue tests have been made oninduction hardened shafts in torsion with crack initiation atthe spline surface.
The influence of pitch errors on fatigue life for splineshas also been estimated, by using a weakest link failureprobability model and combining it with a 2-parameter Weibullfailure distribution model. The conclusion is that pitch errorsin the investigated splines appear to reduce fatigue life byabout 50-70 %, compared with ideal pitch.

Celestica, a global contract manufacturer specializing in printed circuit board assembly and computer assembly, has recently begun manufacturing equipment for the optical networking equipment (ONE) industry. The expansion to include ONE manufacturing requires the development of new skills in handling optical fiber and components, a new supply chain strategy, and a new approach to manufacturing systems control. Celestica is developing a set of standards for ONE manufacturing that will support the rapid development of the new skills required for this industry. This work outlines the standards and explores the specific issues related to manufacturing with optical fiber, including the mechanical reliability and optical performance of various types of optical fibers. An overview of the telecommunications industry is provided, including an analysis of its supply chain structure. Observations are made on trends in the industry and the ways that these trends have affected Celestica in the past, and could impact Celestica in the future. Finally, Celestica's current approach to manufacturing systems control is evaluated, and suggestions are made for improving systems control and project management when manufacturing for such a rapidly evolving industry.

Повний текст джерелаSyftet med detta projekt är att utveckla en specialiserad utrustning för kallvattensurfare att använda vid ombyte före och efter en surfsession. Surfutrustningen som finns tillgänglig på marknaden idag är utformad för varmare väder och vattentemperatur och täcker inte alla behov som surfare i de nordliga länderna i Europa och Amerika har. En förstudie genomfördes för att bättre förstå behoven hos kallvattensurfarna från de olika nordliga länderna. Många fältstudier utfördes också vid Nynäshamn, en surfvattenplats för kallt vatten nära Stockholm i Sverige. Därefter genomfördes en idégenereringsprocess och konceptgenereringsprocess för att hitta de bästa lösningarna på problemet. Efter att ha valt det bästa konceptet vidareutvecklades det i detalj. Slutprodukten blev en silikonhink och en isolerande värmematta med en torrpåse, som möjliggör förvaring av både torrt och vått redskap samtidigt. Den har också ett enkelt avlopp för att tömma kvarvarande vatten före transport.

This thesis recommends a China business and equipment strategy for the Controls Conveyor Robotics Welding (CCRW) group at General Motors. The current strategy is to use globally common equipment through predetermined global suppliers. The GM facilities in China, which are jointly owned with non-GM entities, believe that a local sourcing strategy would reduce lead times, transportation costs and increase the level of nearby service and support. These factors are catalyst for GM to reevaluate the current global common strategy. This thesis will provide an overview of the CCRW organization and discuss how the sourcing strategy has evolved through globalization. Due to the large variety of production tooling, this thesis will narrow the focus to two case studies: the first being a Main Control Panel (MCP) and the second being a weld controller. These case studies are used as a method to determine the pros and cons of the current sourcing strategy, where the MCP is a highly integrated design maintained by CCRW HQ and the weld controller is a "blackbox" which CCRW defines the functional specifications and procures "off the shelf' from a predetermined global supplier. Through local China visits, literature review and preliminary cost assessments, it was determined that while local sourcing may be a viable option for both the MCP and weld controller, there is not enough determinate information to commit to a sourcing change in the case of the Main Control Panel. From onsite visits to potential MCP option suppliers in China, it appears that likely "local" arrangements exists, however, further company analysis and validation will need to be conducted to adopt the change.
(cont.) As for the weld controller, the local product variation with the current global supplier (based locally) is recommended and was validated by CCRW weld engineers by the completion of this internship. I The term "Local" will be used throughout this thesis to refer to "China," meaning solutions that are derived from internal to China.

This thesis tackles the Supermarket (SMKT) material shortage problem at Varian Semiconductor Equipment and Associates (Varian), in a bid to improve the SMKTs On-Time Delivery. The SMKT is a sub-assembly area that creates intermediate assemblies in a multi-stage ion implanter production process. However, many sub- assemblies made in the SMKT are delivered late. When juxtaposed with Varians external suppliers, which have On-Time Delivery records of over 90%, the SMKTs average of 61% pales in comparison. SMKTs poor On-Time Delivery has been tied to production delays and rework downstream on the Flowline. From a large amount of data collected on-site, a SMKT material shortage problem is found to be the root cause of its unsatisfactory On-Time Delivery. Random supply shocks have resulted in material shortages, which in turn lead to late deliveries. The majority (i.e. 64%) of shortages is the result of having two inventory storage locations: SMKT and Varians Warehouse. To resolve the material shortage problem, Varian can consider consolidating its SMKT inventory to one single storage location, such as the Warehouse. This is expected to save Varian $467,488 per annum in labor hours and rent, free up 3,000 ft2 of production floor space for capacity expansion, and decrease cycle time of an oft-late sub-assembly called the Profiler by 11%. This is on top of eliminating the aforementioned 64% of shortages. The consolidation strategy will put Varian in a productive and competitive position to capitalize on the fast-growing semiconductor industry in the years ahead.

Повний текст джерелаTo save time in Flextronics high volume production, the time for test and calibration of mobile telephones need to be as short and accurate as possible. In the wideband code division multiple access (WCDMA) case, the output power calibration is the most critical calibration concerning accuracy. The aim with this thesis was to find a faster calibration method than the one that exists today and still retain accuracy.
The Third Generation Partnership Project (3GPP) outlines the requirements of the output power and they must be thoroughly considered when choosing calibration method. Measurement accuracy and the behavior of the transmitter chain parameters also must be considered.
The output power in the WCDMA phone studied is controlled by seven parameters. The parameters are characterized in this thesis, and are found to be too hardware dependent to be predicted or to be seen as predictions from each other.
Since no parameter predictions are possible it was stated that all parameters have to be measured, and a new way of measuring them in a faster way is proposed. The principle of the new measurement method is presented, and the implemented software is tested and evaluated. The new method mainly makes use of the spectrum analyzer zero span function.
The evaluation shows that the new method is faster than the original and retains accuracy. The measurement uncertainties even seem to diminish, which implicates decreased temperature dependence due to faster measurement time.

Toyota Motor Manufacturing North America (TMMNA) is continuing to face an increasingly competitive automobile market. To meet these evolving market conditions, TMMNA has experienced rapid growth in demand for its automobiles in North America. To meet this demand, Toyota has rapidly grown from three assembly plants in the mid- 1990's to its current total of six assembly plants (five in operation with one being built). This has led to many management challenges, including communication, knowledge sharing, and knowledge retention that many companies experience when faced with rapid growth. In order to respond to these challenges, Vehicle Production Engineering (VPE) Assembly, a department within TMMNA, has attempted to develop a process through which it can standardize its processes and capitalize on best practices across the many North American plants. This thesis studied the process through which VPE Assembly develops and installs assembly line equipment for major automobile model changes. This study included observation of the Toyota product development process and how this process is carried out within VPE Assembly. This research revealed that the assembly line equipment process employed by Toyota is well suited for this organization. However, there are improvements available that could improve the overall process and bring automobiles models to the market more quickly. Communication between the different plants could be improved. Additionally, much knowledge learned from completed projects is not being shared fully between the various plants. Suggested improvements to address these problems are discussed.

This system will use intermittent on- and off-line, condition monitoring based on ANNs and expert systems (ES). A functional overview is discussed. The data would identify where and what is the particular machine alarm condition. Such an approach would allow improved fault detection of machine components, especially in mines where trained personnel are not readily available. (Abstract shortened by UMI.)

Повний текст джерелаEn viktig del av en hållbar utveckling är energieffektiva lösningar för uppvärmning av byggnader. En vanlig lösning i Sverige är att använda en värmepump kopplad till en borrhålsvärmeväxlare och utnyttja berggrunden som värmekälla. I vissa fall är det motiverat att testa bergets värmeledningsförmåga med hjälp av ett termiskt responstest för att mer precist kunna dimensionera borrhålen. Denna mastersuppstas gjordes i samarbete med Bengt Dahlgren geoenergi. Arbetet syftade till att designa en kompakt utrustning för termiskt responstest, testa den nya utrustningen på en koaxial borrhållsvärmeväxlare och utvärdera testresultatet samt att designa en enkel affärsmodell för den nya utrustningen. Företaget hade sedan tidigare en utrustning för termiskt responstest, som låg till grund för designen av den nya. En litteraturstudie utfördes för att få mer kunskap om termisk responstestutrustning, dess komponenter och borrhålsvärmeväxlare. Dessutom gjordes en utvärdering av mätresultat från ett tidigare utfört test på ett 800m djupt borrhål med en koaxial borrhålsvärmeväxlare. Arbetet resulterade i en ny kompaktare utrustning för termiskt responstest med en ny smart lösning för uppvärmningen. Två olika affärsmodeller baserade på uthyrning av den nya utrustningen togs fram. Utrustningen testades på ett 200 m djupt borrhål med en koaxial borrhålsvärmeväxlare. Borrhålet visade en termisk värmeledningsförmåga på 2,46 𝑊𝑚∙𝐾 och ett borrhålsmotstånd på 0,031 m∙KW

Повний текст джерелаDynamisk gradering är ett alternativt sätt att gradera utrustning i elkraftsystem (luftledningar, transfor-matorer). Den rådande normen är en statisk gradering som är satt för att säkerställa att systemet håller sig inom säkerhetsgränserna även vid ofördelaktiga förhållanden. En dynamisk gradering beräknar lastbarheten kontinuerligt utifrån realtids eller prognosticerade mätvärden. Detta tillåter drift närmare de faktiska säkerhetsgränserna, vilket ökar utrustningens överföringskapacitet. Det är således ett attraktivt forskningsområde inom elkraftmarknaden, då utbyggnad av överföringskapacitet i nuläget ofta är förenat med stora kostnader och långa handläggningstider.I Oktober 2019 påbörjade Ellevio AB tillsammans med Heimdall Power ett pilotprojekt om dynamisk lastbarhet. Mätutrustning utvecklad av Heimdall Power monterades på en regionalledning, för att utforska potentialen hos både mätutrustningen och den dynamiska lastbarheten för ledningen i fråga. Det här examensarbetet har som en del i pilotprojektet haft som mål att besvara frågor gällande den potentiella ökningen i överföringskapacitet och de ekonomiska konsekvenserna av detta, samt analysera mätutrustningens tillförlitlighet och optimala placering längs ledningen.En metod för att finna de mest kritiska punkterna längs ledningen har tagits fram i samband med examensarbetet. Metoden är baserad på en litteraturstudie av tidigare metoder, och använder tre faktorer för att göra en riskskattning av varje span på ledningen. Metoden applicerades sedan på ledningen i pilotprojektet för att finna de mest kritiska punkterna för att placera mätutrustning.Analysen av mätutrustningens tillförlitlighet visade att temperaturmätningarna hos Heimdalls neuroner inte fungerade korrekt. Detta har senare bekräftats genom tester från Heimdall.Den potentiella överföringskapaciteten ökade i genomsnitt med 23% då dynamisk gradering implementerades. En positiv korrelation mellan den dynamiska graderingen och lastprofilen från vindkraftsproduktion i området har också påvisats. Den ekonomiska analysen visade att det potentiella ekonomiska värdet från denna ökning beror på mängden nyetablering av vindkraft, och att värdet från implementering av dynamisk gradering då som mest är 4.1 MSEK.Sammanfattningsvis har det här examensarbetet påvisat både möjligheter och utmaningar kring dynamisk gradering. Vidare behöver ovanstående analyser göras ånyo då mer mätdata samlats in, för att kunnabekräfta eller förkasta slutsatserna i rapporten.

Повний текст джерелаTestning av aktiv säkerhet och framför allt automatisk nödbroms sker oftast med en testrigg som simulerar att en fotgängare korsar gatan framför ett fordon. Detta examensarbetet går ut på att validera noggrannheten för en ny liknande testrigg somtagits fram av AstaZero, företaget och testanläggningen där examensarbetet utfördes. Denna rigg fungerar genom att släpa en platta, med exempelvis en fotgängardocka på, framför ett fordon som då tvingas aktivera nödbromsen. Genom ett flertal tester medvanliga scenarion har olika parametrar testats, exempelvis hastighet och vikt förplattan, och resulterat i data som analyserats. Datainsamlingen gjordes med hjälp avutrustning som innehåller accelerometer, gyroskop och GPS-system. Dessa systemvar under testerna monterade på riggen. Syftet med analysarbetet var att visualiseradata för lateral och longitudinell noggrannhet samt hur stabil hastigheten är. Resultaten från analysen visade att hastigheten hade ett svängande beteende. Detta löstes genom att antingen implementera Jerk, som jämnar ut accelerationen, eller att sänka den totala vikten på plattan som släpas på backen. Data från testerna visade att standardavvikelsen för longitudinell position är cirka 10 mm och för lateral position mellan 15 mm och 40 mm, mest beroende på testlängd och vikt på plattan.

Delivery of subsea equipment and sensors is generally accomplished with unguided sinking platforms or powered autonomous underwater vehicles (AUVs). An alternative would be to augment existing platforms with navigation and guidance capability, enabling them to actively guide themselves to their destination, with minimal added complexity and power consumption. This defines a new class of AUV having 110 propulsion, which we call the Vertical Glider. This thesis investigates the challenges posed by this deployment concept, and describes in detail a prototype vertical glider that was built for initial tests. We explore through computer simulation the specific roles of various operating parameters, such as control gain, measurement noise, and process noise, on the overall vehicle performance. The prototype vehicle has been successfully pool-tested, and serves as a baseline platform for open water operations and multi-vehicle deployments.
