Abstract: Full-scale testing of vehicles is notoriously difficult and expensive. Invariably only a small range of vehicle configurations and soil conditions can be explored and it is difficult to ensure consistency and uniformity of terrain. Scale-model testing may provide a more versatile and cost-effective method for exploring the behaviour of off-road vehicles. This paper describes some of the simple rules which have to be observed when modelling vehicle operations on soil and presents results from three case studies of scale-model tests on tracked vehicles and earth anchors carried out in soil bins at The Royal Military College of Science (RMCS) in the United Kingdom. The results are shown to correlate well with theoretical predictions of full-scale performance and with empirical predictions based on full-scale trials.
