Terramechanics and Off-Road Vehicle Engineering, 2nd Edition

Book Description

This book will be of great interest to any professional engineer or automotive engineering student working on off-road vehicles. Reflecting the increase in off-road vehicle production and development—recreational, agricultural, construction, military—this book equips readers with all of the necessary knowledge to successfully design and model off-road vehicle systems, and provides a comprehensive introduction to terramechanics, the mechanics of vehicle/terrain interaction.

  • The only book to cover the principles of off-road vehicle and terrain engineering, a rapidly developing sector that includes SUVs, tractors and agricultural vehicles, military vehicles, and construction equipment
  • Covers the latest developments in the field, including the latest computer-aided methods employed in the development of new generation of high-mobility off-road vehicles in Europe, North America and Asia.
  • Ideal for professional reference and course reference by students, with new detailed worked design examples, case studies, and accompanying problems and solutions.
