OFF-ROAD MOBILITY RESEARCH, VOLUME 1
Abstract
A summary of research and engineering studies conducted on a long- range program of off-road mobility research is presented. These studies, some of which are only partially completed, are directed at providing technical knowledge which is required to match off-road vehicles with military mobility requirements. A hybrid computer model is described which will permit predicting vehicle dynamics performance of simulated vehicles traversing a broad spectrum of off-road situations. A critique of existing soil trafficability theories is made based on a review of the literature which treats the comparison of vehicle performance prediction with experimental results. Analytical and experimental studies of the velocity field and soil fabric in clay soil exposed to dynamic loads are summarized. A general method is discussed for processing mobility related environmental information and for mapping vehicle performance by computer methods. A concept is introduced for testing vehicles in relation to the total environment in order to define the vehicle performance envelope. Also a method is introduced for displaying potential vehicle performance in selected geographic areas and for producing 'testable' specifications for off-road vehicles. Engineering studies of an off-road driving simulator for synthesizing dynamic visual displays and vehicle motion in the laboratory are reviewed.
