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.
This textbook covers handling and performance of both road and race cars. Mathematical models of vehicles are developed always paying attention to state the relevant assumptions and to provide explanations for each step. This innovative approach provides a deep, yet simple, analysis of the dynamics of vehicles. The reader will soon achieve a clear understanding of the subject, which will be of great help both in dealing with the challenges of designing and testing new vehicles and in tackling new research topics. The book deals with several relevant topics in vehicle dynamics that are not discussed elsewhere and this new edition includes thoroughly revised chapters, with new developments, and many worked exercises. Praise for the previous edition: Great book! It has changed drastically our approach on many topics. We are now using part of its theory on a daily basis to constantly improve ride and handling performances. --- Antonino Pizzuto, Head of Chassis Development Group at Hyundai Motor Europe Technical Center Astonishingly good! Everything is described in a very compelling and complete way. Some parts use a different approach than other books. --- Andrea Quintarelli, Automotive Engineer
In most forms of racing, cornering speed is the key to winning. On the street, precise and predictable handling is the key to high performance driving. However, the art and science of engineering a chassis can be difficult to comprehend, let alone apply. Chassis Engineering explains the complex principles of suspension geometry and chassis design in terms the novice can easily understand and apply to any project. Hundreds of photos and illustrations illustrate what it takes to design, build, and tune the ultimate chassis for maximum cornering power on and off the track.
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.
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.
Based on the principles of engineering science, physics and mathematics, but assuming only an elementary understanding of these, this textbook masterfully explains the theory and practice of the subject. Bringing together key topics, including the chassis frame, suspension, steering, tyres, brakes, transmission, lubrication and fuel systems, this is the first text to cover all the essential elements of race car design in one student-friendly textbook. It avoids the pitfalls of being either too theoretical and mathematical, or else resorting to approximations without explanation of the underlying theory. Where relevant, emphasis is placed on the important role that computer tools play in the modern design process. This book is intended for motorsport engineering students and is the best possible resource for those involved in Formula Student/FSAE. It is also a valuable guide for practising car designers and constructors, and enthusiasts.
Through appendices and diagrams, Car Suspension and Handling, 4th Edition outlines the purpose and history of vehicle suspension systems, while defining the basic parameters of suspension geometry. In addition, the book delves into human sensitivity to vibration, and offers data on durability, tire background information, steering calculations and suspension calculations.
This set includes Race Car Vehicle Dynamics, and Race Car Vehicle Dynamics - Problems, Answers and Experiments. Written for the engineer as well as the race car enthusiast, Race Car Vehicle Dynamics includes much information that is not available in any other vehicle dynamics text. Truly comprehensive in its coverage of the fundamental concepts of vehicle dynamics and their application in a racing environment, this book has become the definitive reference on this topic. Although the primary focus is on the race car, the engineering fundamentals detailed are also applicable to passenger car design and engineering. Authors Bill and Doug Milliken have developed many of the original vehicle dynamics theories and principles covered in this book, including the Moment Method, "g-g" Diagram, pair analysis, lap time simulation, and tyre data normalization. The book also includes contributions from other experts in the field. Chapters cover: *The Problem Imposed by Racing *Tire Behavior *Aerodynamic Fundamentals *Vehicle Axis Systems and more. Written for the engineer as well as the race car enthusiast and students, the companion workbook to the original classic book, Race Car Vehicle Dynamics, includes: *Detailed worked solutions to all of the problems *Problems for every chapter in Race Car Vehicle Dynamics, including many new problems *The Race Car Vehicle Dynamics Program Suite (for Windows) with accompanying exercises *Experiments to try with your own vehicle *Educational appendix with additional references and course outlines *Over 90 figures and graphs This workbook is widely used as a college textbook and has been an SAE International best seller since it's introduction in 1995.
