Abstract : The major portion of the motion resistance forces encountered by vehicles traveling off-road is caused by the deformation of the ground under the vehicle load. Tracks were originally conceived as implements to distribute the vehicle load over a large area and thereby reduce the pressure to, and deformation of the ground. Tracked vehicles with rigid suspension systems distribute ground pressures nearly evenly and can, at low speed, traverse soft terrain not negotiable by other vehicles.
