Download or read book Vehicle Dynamic Validation and Analysis from Suspension Forces written by William Scott Murray and published by . This book was released on 2012 with total page 121 pages. 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.

Book excerpt: The authors examine in detail the fundamentals and mathematical descriptions of the dynamics of automobiles. In this context, different levels of complexity are presented, starting with basic single-track models up to complex three-dimensional multi-body models. A particular focus is on the process of establishing mathematical models based on real cars and the validation of simulation results. The methods presented are explained in detail by means of selected application scenarios. In addition to some corrections, further application examples for standard driving maneuvers have been added for the present second edition. To take account of the increased use of driving simulators, both in research, and in industrial applications, a new section on the conception, implementation and application of driving simulators has been added.

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.

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.
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 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.

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.
