One of the most widely used conventional methods for predicting tracked vehicle performance is based on the assumption that the track in contact with the terrain is equivalent to a rigid footing. Furthermore, a uniform normal pressure distribution over the entire contact area is assumed if the centre of gravity of the vehicle is located at the midpoint of the contact length. On the other hand, if the centre of gravity is located in front of or behind the midpoint of the contact length or if load transfer due to drawbar pull takes place, a sinkage distribution of trapezoidal shape will then be assumed. Based on these assumptions and the measured pressure-sinkage and shear stress- displacement relationships of the terrain, the tractive performance of tracked vehicles is predicted.
