Abstract: This study reviews the basic principles governing motion in cross country vehicle operation. The study then examines the cross-country vehicle computational modelling method developed by the author|s research group for the Hungarian Army. The study describes the general structure of this model and shows how to compute the vehicle velocity constrained by vibrational acceleration, and presents some of the results of these computations. Finally the author evaluates the results accomplished under this research project and outlines what steps seem to be necessary for further progress. This study was performed under the sponsorship of the US Army European Research Office.
