Available in PDF, EPUB and Kindle. Book excerpt: Author's Abstract: The importance of standardized courses for testing Georgia Southern University's Formula SAE (FSAE) vehicle is emphasized in order to reproduce test results and analyze trends within data. The test courses are clearly defined so that future Eagle Motorsports (EMS) participants can replicate testing conditions to track progress from year to year as well as validate simulations and design models. A data acquisition system (DAQ) was installed on the FSAE car for the first time. This paper serves as an introduction to the purpose of acquiring data, an explanation of the hardware available and components chosen to implement DAQ on Georgia Southern's FSAE car. Mathematical validation is presented to complement the data acquired from the DAQ and the results from testing are evaluated. This data may be used to validate simulations, models, or evaluate changes in vehicle behavior during the tuning process.

Available in PDF, EPUB and Kindle. Book excerpt: Several standardized courses for Formula SAE (FSAE) testing are introduced and described with sufficient detail to be reproduced by any Formula SAE team. Basic analysis methods for the courses are given as well as explanations of how those analyses could be used. On-car data from the Global Formula Racing (GFR) SAE cars is used to verify the analysis methods, give estimates to unknown variables, and show the relevance of the standard testing courses. Using the courses and methods described in this paper should allow standardized comparison of FSAE car performance, as well as provide a method to verify simulations and evaluate changes in vehicle performance from tuning. Instrumentation of all suspension member forces with strain gauge load cells is shown to be an extremely powerful tool for measuring vehicle performance and quantifying vehicle dynamic characteristics. The design and implementation of strain gauge load cells is described in detail to provide a template for reproducing similar results in other vehicles. Data from the GFR 2011 FSAE car is used throughout the paper to: show the design process for making effective suspension member load cells, show the calibration processes necessary to ensure quality data is collected, illustrate the calculation of suspension corner forces, and show the effectiveness of measuring vehicle dynamic characteristics with this technique. Using the methods described in this paper should provide data that allows a more complete and thorough understanding of on-car vehicle dynamics. This data may be used to validate vehicle models.

Download or read book Full Vehicle Dynamics Model of a Formula SAE Racecar Using ADAMS Car written by Russell Lee Mueller and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Complete Multi body Model for an FSAE Space Frame Car written by Tejas N. Chothani and published by . This book was released on 2013 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicle dynamics has evolved into an increasingly indispensible discipline to supplement the design of automobiles, especially racecars. Every single component of the car and the environment with which it interacts contributes to the overall dynamic behavior of the vehicle. For Formula Society of Automotive Engineers (FSAE) cars in particular, these parameters become extremely critical and hence require robust and accurate physical testing methods, which are expensive and time consuming, warranting the need for virtual testing methods. The Bearcat Motorsports team (BCMS) lacked this capability of predicting vehicle dynamic behavior, relying on previously available test data and the performance of the car after fabrication. Hence, a thorough multi-body dynamics model has been developed to overcome this inadequacy. The 2013 race car is used for this study and ADAMS/Car is used as a multi-body development platform. ADAMS/Car multi-body model consists of different automotive subassemblies modeled as independent subsystems, which can interact amongst themselves to mimic the overall dynamics of a physical car model. Each subsystem requires data pertaining to its characteristics such as mass, inertia, center of gravity, which can be tuned to calibrate and eventually validate the model against data obtained from physical testing. This makes it imperative to bring together the work done by all sub-system teams over the course of the year. For simulation of road-tire interface, the PAC2002 tire model [2] is used, which is the latest Pacejka Tire Model. A new ADAMS template is made for the anti-roll bars and the strut structure. The model can predict full vehicle dynamic behavior apart from generating sub-system specific vehicle dynamic parameters. The validation of a full vehicle model is a multi-year project and is not within the scope of this thesis. However, the initial dynamic model is now able to help the team predict vehicle dynamic trends and evolve their designs based on previous design ideologies. The future work for this project will include further calibration and validation of the model and then running the simulation model on a complete virtual endurance track.

This book was released on 2013-02-12 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compendium is an update to two best-selling editions published by SAE International in 1995 and 2003. Editor Doug Fehan has assembled a collection of technical papers from the SAE archive that will inspire readers to use race engine development as an important tool in the future of transportation. He focuses on several topics that are important to future race engine design: electrification, materials and processes, and improved technology. Today’s electric hybrid vehicles and kinetic energy recovery systems embody what inventors envisioned in the early 1900s. First employed in trams and trains of that era, the technology was almost forgotten until racers resurrected their version in 2009 F-1 racing. The automotive industry has long admired the aircraft industry’s use of lightweight metals, advanced finishing processes, and composites. The use of these materials and processes has helped reduce overall mass and, in turn, improved speed, performance, and reliability of race engines. Their initial high cost was a limiting factor for integrating them into mass-produced vehicles. With racing leading the way, those limitations were overcome and vehicles today feature some amazing adaptations of those processes and materials. Engine power, efficiency, durability, reliability, and, more recently, emissions have always been of primary importance to the automotive world. The expanding use of electrification, biofuels, CNG, high-pressure fuel delivery systems, combustion air management, turbocharging, supercharging, and low-viscosity lubricants have been the focus of race engine development and are now turning up in dealer showrooms. The papers in this publication were selected for two reasons: they demonstrate the leadership that racing plays in the future of automotive engineering and design as it relates to engines; and they will be interesting to everyone who may be in racing and to those who may want to be in racing.

Download or read book Vehicle Dynamics and Control written by Rajesh Rajamani and published by Springer Science & Business Media. This book was released on 2011-12-21 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems. The control system applications covered in the book include cruise control, adaptive cruise control, ABS, automated lane keeping, automated highway systems, yaw stability control, engine control, passive, active and semi-active suspensions, tire-road friction coefficient estimation, rollover prevention, and hybrid electric vehicles. In developing the dynamic model for each application, an effort is made to both keep the model simple enough for control system design but at the same time rich enough to capture the essential features of the dynamics. A special effort has been made to explain the several different tire models commonly used in literature and to interpret them physically. In the second edition of the book, chapters on roll dynamics, rollover prevention and hybrid electric vehicles have been added, and the chapter on electronic stability control has been enhanced. The use of feedback control systems on automobiles is growing rapidly. This book is intended to serve as a useful resource to researchers who work on the development of such control systems, both in the automotive industry and at universities. The book can also serve as a textbook for a graduate level course on Vehicle Dynamics and Control.
