Shrivenham, UK, for the Department of the Army, United States Army Research Laboratory, Aberdeen Proving Ground, Maryland, USA. The scope of the study covers Terrain Accessibility (Section 1), Suspension and Automotive Performance (Section 2) and Other Factors (Section 3) in connection with tracked and wheeled armoured fighting vehicles (AFVs) in the 10 to 25 US ton range. Two aspects of terrain accessibility were covered in detail - soft-soil trafficability and obstacle crossing. Several different predictive methods were used to compare the trafficability of a sample of sixteen AFVs in the 10 to 25 US ton range, for clay soils and sands. The sample comprised eight tracked vehicles and eight wheeled vehicles, four of which were equipped wide a central tyre inflation system (CTIS). There were considerable differences in the predictions derived from the various methods, but some clear trends emerged. 收起
