Terramechanics is the broad study of terrain-vehicle systems. In this book, all physical processes associated with the static and dynamic interplay between powered and tooled wheeled or tracked vehicles with natural and man-made surfaces are analysed and mathematically modelled.The focus of the book is the technical problem of predicting the p

An updated edition of the classic reference on the dynamics of road and off-road vehicles As we enter a new millennium, the vehicle industry faces greater challenges than ever before as it strives to meet the increasing demand for safer, environmentally friendlier, more energy efficient, and lower emissions products. Theory of Ground Vehicles, Third Edition gives aspiring and practicing engineers a fundamental understanding of the critical factors affecting the performance, handling, and ride essential to the development and design of ground vehicles that meet these requirements. As in previous editions, this book focuses on applying engineering principles to the analysis of vehicle behavior. A large number of practical examples and problems are included throughout to help readers bridge the gap between theory and practice. Covering a wide range of topics concerning the dynamics of road and off-road vehicles, this Third Edition is filled with up-to-date information, including: * The Magic Formula for characterizing pneumatic tire behavior from test data for vehicle handling simulations * Computer-aided methods for performance and design evaluation of off-road vehicles, based on the author's own research * Updated data on road vehicle transmissions and operating fuel economy * Fundamentals of road vehicle stability control * Optimization of the performance of four-wheel-drive off-road vehicles and experimental substantiation, based on the author's own investigations * A new theory on skid-steering of tracked vehicles, developed by the author.

Three pneumatic tires were used in a laboratory study to compare the performance of dual wheels at zero spacing with the performance of single wheels and to determine the influence of tire spacing on dual-wheel performance. One-pass tests were conducted on air-dry, medium dense to very dense sand. The data were analyzed for powered wheels in terms of pull, torque, and sinkage coefficients and of efficiency, all at 20 percent slip, and for towed wheels in terms of towed force coefficients. The existing WES performance prediction system was used in both cases. Results showed that a powered dual wheel at zero spacing, considered as two wheels sharing equal load and exhibiting equal performance, outperformed a single wheel with the same characteristics as each wheel of the dual-wheel configuration. The performance of powered dual wheels decreased with increasing wheel spacing until the two wheels performed like single wheels. This critical spacing was reached when it became two to three and one-half times the width of one of the wheels. A dual wheel at zero spacing, considered as one wheel, performed practically the same as a single wheel with the same characteristics of the dual-wheel configuration; however, the dual wheel with zero spacing performed more efficiently than the single wheel over a certain range of load, deflection, and soil strength combinations.
