Criteria commonly used for evaluating the performance of various types of off-road vehicle are reviewed in Chapter 6. Empirical and semi-empirical methods for predicting tracked vehicle performance are discussed in Chapter 7.
Chapter 8 outlines the analytical basis for the computer-aided method NTVPM for performance and design evaluation of vehicles with flexible tracks, such as military and cross-country transport vehicles. Examples of its applications to the development of new products in off-road vehicle industry are presented.
Chapter 10 outlines the analytical basis for the computer- aided method RTVPM for performance and design evaluation of vehicles with long-pitch link tracks, such as industrial and agricultural tractors. Chapter 11 presents empirical and semi- empirical methods for predicting wheel and wheeled vehicle performance. The analytical basis for the computer-aided method NWVPM for predicting the performances of wheels and wheeled vehicles is outlined in Chapter As an example, the application of NWVPM to the evaluation of the performance of lunar vehicle wheels is presented.
Some of the material included in this new edition has been presented at professional devel- opment programmes and seminars in many countries. This new edition includes some of the results of recent research on off-road vehicle mobility car- ried out by the author together with his associates at Carleton University and at Vehicle Systems Development Corporation VSDC , Ottawa, Canada. Appreciation is due also to many organizations, in private and public sectors, for their generous support for our research over the years.
Jo Yung Wong Ottawa, Canada Preface to the First Edition In the past few decades, the continual demand for greater mobility over a wider range of ter- rains and in all seasons by agricultural, construction and cross-country transport industries and by the military has stimulated a great deal of interest in the study of vehicle mobility over unprepared terrain.
A large volume of research papers on this subject has been published in journals and conference proceedings of learned societies. A variety of methods for predict - ing and evaluating off-road vehicle performance, ranging from entirely empirical to highly theoretical, has been proposed or developed. However, methods that will enable the design engineer or the procurement manager to conduct a comprehensive and yet realistic evaluation of competing vehicle designs appear to be lacking.
This prompted the author of this book to embark, more than a decade ago, on a series of research programmes aimed at filling this gap. The objective is to establish mathematical models for vehicle—terrain systems that will enable the engineering practitioner to evaluate, on a rational basis, a wide range of options and to select an appropriate vehicle configuration for a given mission and environment.
To be useful to the design engineer or the procurement manager, the models should take into account all major vehicle design and operational parameters as well as pertinent terrain characteristics. After more than a decade of intense effort, a series of computer-aided methods computer simulation models for predicting and evaluating the performance of tracked and wheeled vehicles, which meet the basic objective outlined above, have emerged.
These methods have since been used to assist off-road vehicle manufacturers in developing new products and governmental agencies in evaluating vehicle candidates with most encouraging results.
The encouragement that these developments have effected has convinced the author to put these pages together, with the hope that this book may enhance the interest of the professionals engaged in the field of off-road vehicle mobility. This book summarizes some of the research and development work on the computer-aided methods for evaluating off-road vehicle performance carried out by the author and his asso- ciates at the Transport Technology Research Laboratory, Carleton University and Vehicle Systems Development Corporation, Ottawa, Canada.
Chapter 1 provides an introduction to the subject of terramechanics, and outlines its roles and basic issues.
Chapter 2 describes the tech- niques and instrumentation for measuring terrain behaviour. An understanding of the mechani- cal properties of the terrain is of importance in the prediction and evaluation of off-road vehicle xi xii Preface to the First Edition performance, as the behaviour of the terrain quite often imposes severe limitations to vehicle mobility.
Chapter 3 describes the responses of various types of natural terrain to normal and repetitive loading. This provides information for predicting the sinkage of the vehicle running gear and the normal pressure distribution on the vehicle—terrain interface.
These methods include empirical and theoretical methods and parametric analysis. The author concludes that parametric analysis, as first developed by Bekker, is the only method which provides techniques which are of practical value to the vehicle designer and user and are also applicable to the design of totally new vehicles or vehicles operating in new environments. The book contains detailed discussion of the practical problems involved in interpreting soil strength measurements, because of the inevitable variability of the data.
There is a particularly valuable section dealing with the statistical analysis of the data and it is shown how the quality of the data obtained can be improved by the use of m o d e m electronic data collection and processing equipment.
Much of this part of the book is taken up by discussion of the particular problems associated with measuring the strength properties of snow and muskeg.
Off-Road Vehicle Engineering
In particular, the author shows how to deal with terrain which recovers between the passage of one wheel and another, by a repetitive loading test, and how to characterise muskeg consisting of a surface mat overlying weaker peat and snow frozen in layers.
The largest section of the book deals with the prediction of tractive performance of tracked vehicles in soft snow, muskeg and soil. This consists of a description of the NTVPM computer model developed by the author and his colleagues. The model is far more comprehensive than any other approach which has been previously developed and enables the effects on performance of all track design features to be investigated.
Experiments carried out to validate the model in snow and muskeg are described and the degree of agreement between measured and predicted results is extremely good, considering that the measurements were made in naturally occurring ground conditions.
