The planar tracked vehicle model used in this investigation consists of two kinematically decoupled subsystems, i.e., the chassis subsystem and the track subsystem. The chassis subsystem includes the chassis fiame, sprocket, idler and rollers, while the track subsystem is represented as a closed kinematic chain consisting of rigid links interconnected by revolute joints. In this tracked vehicle, the recursive kinematic and dynamic fotmulation is used to fmd the vertical force and the distance of the certain track moved in the driving direction along the track. These distances and vertical forces obtained are used to calculate ale sinkage of a terrain. In this study, the finite element method is adopted to analyze the interaction between a tracked vehicle and the terrain. When the tracked vehicle is moving with different speeds on the terrain, the elastic and plastic deformations and the maximum sinkage for the four different types of a isotropic soil are simulated.
