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 performance of a specific vehicle terrain system in the design and operation stages, looking at vehicle specifications, terrain types and uses, and traction performance parameters such as pull and speed. Special features of this book include: * a comprehensive treatment of pneumatic and flexible tyred systems * the presentation of a new method for predicting the performance of track-type vehicles based on small-scale machine model studies * an overview of tyred or tracked vehicles running on weak soil or snow.
