To the late Professor David Crolla, whose advice, knowledge, encouragement and
humour are sorely missed.
To my wife Jacqueline, for her encouragement and tolerance of my many hours
communing with journals, papers, books and my computer.
The automobile is a part of our society, and tightly linked to many aspects of our daily lives. We see a wide variety of vehicles every day, passing us on the streets in our cities and on our motorways. There is of course a vast plethora of different vehicles used for different aspects in our daily lives, and in more special applications. Perhaps some of the more interesting and exciting applications are those that are far removed from our everyday lives. Two of the more famous and popular vehicle applications in the automotive sector are high speed vehicles such as race cars and off‐road vehicles such as large earth‐moving equipment. Being in the field for over 30 years, many of those years as a faculty member, I can testify to the fact that most people get very excited when they are inspecting a top‐rated race car or see these vehicles on the track. The same is true when standing next to or watching large earth‐moving equipment in operation. There is nothing quite like seeing an earth‐mover that is capable of effortlessly hauling the volume of several large sedans up a steep grade out of a mining operation. Of course, the combination of these two areas into High Speed Off‐Road Vehicles is an amalgamation that is not only extremely exciting from an engineering perspective, but one that presents unique challenges to vehicle designers that are not faced in many other automotive sectors.
High Speed Off‐Road Vehicles is an excellent and in‐depth review of vehicle performance in off‐road conditions with a focus on key elements of the running gear systems of vehicles. In particular, elements such as suspension systems, wheels, tyres and tracks are addressed in depth. It is a well‐written text that provides a pragmatic discussion of off‐road vehicles from both a historical and analytical perspective. Some of the unique topics addressed in this book include link and flexible tracks, ride performance of tracked vehicles, and active and semi‐active suspension systems for both armoured and unarmoured vehicles. The book also provides spreadsheet‐based analytical approaches to modelling these topic areas, providing insight into steering, handling and overall performance of both tracked and wheeled systems. The author further extends these analyses to soft‐soil scenarios and thoroughly addresses rollover situations. The text also provides some insight into more advanced articulated systems.
It is quite clear that this text is a unique and valuable addition to the Automotive Series whose primary goal is to publish practical and topical books for researchers and practitioners in industry, and postgraduate/advanced undergraduates in automotive engineering. The series addresses new and emerging technologies in automotive engineering, supporting the development of next‐generation transportation systems. The series covers a wide range of topics, including design, modelling and manufacturing, and provides a source of relevant information that will be of interest and benefit to people working in the field of automotive engineering.
High Speed Off‐Road Vehicles is written from a very pragmatic perspective, based on the author’s extensive experience, and provides an excellent introduction to off‐road vehicles. Simultaneously, it is a strong reference text for those practising design and analysis of such systems. No other text covers the concepts and vehicle systems that are presented in this book. It is an excellent read, very understandable and highly informative. The bottom line is that this book covers a very interesting topic area and is highly unique in its content, making this book a welcome addition to the Automotive Series.
