ABSTRACT: The triangular track conversion system can be quickly swapped on the tyres, exerts a smaller ground pressure with greater adhesion to solve the problem of the vehicle traversing rough and difficult terrain. First, establish a multi-body dynamic model of the track conversion system in Multi-body dynamic environment and then program the macro commands to add many complex contact forces of the dynamic model. Then using the method of a physical prototype obstacle test, verify the correctness of the simulation model. Finally simulate and analyze the straight driving performance of an engineering vehicle assembled with the track conversion system, through the measurement of unladen and laden conditions of driving wheel driving torque, acceleration, track dynamic tension, the centroid vertical acceleration, for research tracked vehicle’s ride comfort and stationarity.
