Abstract

The high speed tracked vehicle has several unique characteristics. These are the effect of the load transfer, the interaction between the track link and terrain, the suspension system, the tension adjuster, and the conditions of the terrain. These characteristics affect the performance of the high speed tracked vehicle. When the high speed tracked vehicle is under the transient state such as the deceleration or the acceleration, the load transfer occurs. This load transfer affects the suspension system. The length, position and angle of the suspension are also changed. Due to the change of the suspension system, the trajectory of the track links is changed. The change of the track trajectory can cause the track links to lose the contact with the wheels. The tension adjuster operates to maintain the contact between track links and wheels. The normal pressure of the tracked vehicle differs from the wheeled vehicle. When the track links contact with a terrain in wide area, the normal pressure of the tracked vehicle is concentrated under the wheels and distributed in the contact area. The terrain conditions affect the tractive force of the tracked vehicle. In this study, the dynamic performance of the high speed tracked vehicle is investigated considering these effects using the TVS(Tracked Vehicle Simulation) program. The simulations for the load transfer, the suspension system, tension adjuster and the track trajectories of the track subsystem are conducted for the motion of the high speed tracked vehicle under the transient state.
