Download or read book Modeling and Control of a Four Wheel Drive Formula SAE Car written by Cheyenne D. Hua and published by . This book was released on 2019 with total page 42 pages. 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 Kinetic Energy Recovery Systems for Racing Cars written by Alberto Boretti and published by SAE International. This book was released on 2013-04-02 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: A kinetic energy recover system (KERS) captures the kinetic energy that results when brakes are applied to a moving vehicle. The recovered energy can be stored in a flywheel or battery and used later, to help boost acceleration. KERS helps transfer what was formerly wasted energy into useful energy. In 2009, the Federation Internationale de l’Automobile (FIA) began allowing KERS to be used in Formula One (F1) competition. Still considered experimental, this technology is undergoing development in the racing world but has yet to become mainstream for production vehicles. The Introduction of this book details the theory behind the KERS concept. It describes how kinetic energy can be recovered, and the mechanical and electric systems for storing it. Flybrid systems are highlighted since they are the most popular KERS developed thus far. The KERS of two racing vehicles are profiled: the Dyson Lola LMP1 and Audi R18 e-tron Quattro. Four SAE technical papers follow the preface and focus on the use of KERS technology in F1 racing. The first paper examines the factors that influence hybrid performance and enable optimization for different racing circuits. The second paper describes a Flybrid KERS designed for the 2009 F1 season. The third paper considers the development of an electric KERS for the 2009 F1 season. The fourth paper presents the challenges and opportunities of the 2014 F1 engine and powertrain rules, particularly as they pertain to KERS. This book has been published for automotive engineers who are interested in hybrid systems, energy recovery, regenerative braking, and improving acceleration. It will also be useful for powertrain designers, researchers, academics, and motorsports professionals (race engineers, team managers, and technology practitioners who design and build racing powertrains).

Download or read book Dynamic Analysis of a Formula SAE Car written by Tommaso Innocenti and published by LAP Lambert Academic Publishing. This book was released on 2013-01 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the definition of a methodology to deeply analyze the dynamic and handling of a Formula SAE car, focusing the attention on the creation of a vehicle model able to simulate almost all the common maneuvers that the formula has to perform during a typical race. During the development of this work, two different models have been created: a 3 DOF one and a 15 DOF one. Both of them, built starting from the effective Formula SAE car geometric and inertial data, have been tested on common maneuvers and the results compared with the real car telemetry, to prove the efficiency and correct response of the simulator. Both the models gave interesting results, always demonstrating to give correct outputs, compared to real car or to commercial software.
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.
Download or read book Power Transmissions written by George Dobre and published by Springer Science & Business Media. This book was released on 2013-07-11 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: This books contains the Proceedings of the 4th International Conference on Power Transmissions, that was held in Sinaia, Romania from June 20 -23, 2012. Power Transmissions is a very complex and multi-disciplinary scientific field of Mechanical Engineering that covers the different types of transmissions (mechanical, hydraulic, pneumatic) as well as all the machine elements involved, such as gears, bearings, shafts, couplings and a lot more. It concerns not only their basic theory but also their design, analysis, testing, application and maintenance. The requirements set to modern power transmissions are really tough to meet: They need to be more efficient, stronger, smaller, noiseless, easier to produce and to cost less. There is a strong demand to become easier in operation and maintenance, or even automatic and in maintenance-free. Last but not least, they should be easily recycled and respect the environment. Joint efforts of specialists from both academia and industry can significantly contribute to fulfill these needs. The main goal of this conference was to bring together experts from all over the world and present the latest developments in the field of Power Transmissions.
