Available in PDF, EPUB and Kindle. Book excerpt: The suspension system of a FSAE (Formula Society of Automotive Engineers) vehicle is a vital system with many functions that include providing vertical compliance so the wheels can follow the uneven road, maintaining the wheels in the proper steer and camber attitudes to the road surface and reacting to the control forces produced by the tires (acceleration, braking and cornering). The members that comprise the suspension are subjected to a variety of dynamic loading conditions – it is imperative that they are designed properly to ensure the safety and performance of the vehicle. The goal of this research is to develop a model for predicting the reaction forces in the suspension members based on the expected load scenarios the vehicle will undergo. This model is compared to the current FSAE vehicle system and the design process is explained. The limitations of this model are explored and future methodologies and improvement techniques are discussed.

Download or read book Racing Chassis and Suspension Design written by Carroll Smith and published by SAE International. This book was released on 2004-05-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hand-selected by racing engineer legend Carroll Smith, the 28 SAE Technical Papers in this book focus on the chassis and suspension design of pure racing cars, an area that has traditionally been - farmed out - to independent designers or firms since the early 1970s. Smith believed that any discussion of vehicle dynamics must begin with a basic understanding of the pneumatic tire, the focus of the first chapter. The racing tire connects the racing car to the track surface by only the footprints of its four tires. Through the tires, the driver receives most of the sensory information needed to maintain or regain control of the race car at high force levels. The second chapter, focusing on suspension design, is an introduction to this complex and fascinating subject. Topics covered include chassis stiffness and flexibility, suspension tuning on the cornering of a Winston Cup race car, suspension kinematics, and vehicle dynamics of road racing cars. Chapter 3 addresses the design of the racing chassis design and how aerodynamics affect the chassis, and the final chapter on materials brings out the fact that the modern racing car utilizes carbon construction to the maximum extent allowed by regulations. These technical papers, written between 1971 and 2003, offer what Smith believed to be the best and most practical nuggets of racing chassis and suspension design information.
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 The Design of an Innovative Automotive Suspension for Formula SAE Racing Applications written by Jared Michael Darius and published by . This book was released on 2019 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis details an analytical approach to an innovative suspension system design for implementation to the Formula SAE collegiate competition. It focuses specifically on design relating to geometry, mathematical modeling, energy element relationships, and computer analysis and simulation to visualize system behavior. The bond graph approach is utilized for a quarter car model to facilitate understanding of the analytical process, then applied to a comparative analysis between two transverse half car models. The second half car model contains an additional transverse linkage with a third damper, and is compared against the baseline of the first half car model without the additional linkage. The transverse third damper is an innovative design said to improve straight-line tire contact during single-sided disturbance, help mitigate the adverse effects of squat and dive, while not inhibiting the function of the anti-roll bar in cornering capability. Additional work is done investigating an optimization of suspension geometry through mathematical modeling in MATLAB of a four-bar linkage system. This code helps visualize the complex motion of the upright and calculates the wheel camber rate and variation to compare against tire data analysis to match maximum tire performance characteristics with camber angle.

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 Design and Optimization of a Formula SAE Racecar Chassis and Suspension written by Reid F. Allen and published by . This book was released on 2009 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing and constructing a chassis and suspension system for a Formula SAE racecar is a highly complex task involving the interaction of hundreds of parts that all perform an essential function. This thesis examines the critical factors in designing and implementing a Formula SAE chassis from the ground up, with a focus on the performance and optimization of the vehicle as an entire system rather than a collection of individual parts. Analysis includes examining the stiffness, strength, and weight of each part, as well as design verification. The thesis will serve as a summary of the knowledge that I have accumulated over four years of personally designing and overseeing the manufacturing of the MIT Motorsports suspension, provide insight into the design of the MY2009 vehicle, and act as a guide for future chassis designers.

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: In 2006, a small unavailing university auto racing team began building a racecar that would challenge the best engineering schools in the world. With fewer people and resources than any of the top competitors, the only way they were going to win was to push the limit, go for broke, and hope for more than a little luck. By the time they got to the racetrack, they knew: In the fog of fierce competition, whether you win or lose, you learn the hardest lessons about engineering, teamwork, friendship, and yourself.
