With wheel-track vehicle as the research object, the passivity of track walking device on soft road conditions have been studied, establishing the track walking device dynamic model and finishing the dynamic simulation. By the theoretical calculation and dynamic silulation analysis: the method of average ground pressure to represent the vehicle’s passivity on soft road condition has limitations, the average maximum pressure P_mm(MMP) evaluation method is more effective and more accurate; with the same track grounding length, the more wheels of the track walking device, the smaller the vehicle’s subsidence on soft road conditions and the better its passing performance. When a track walking device was increased from one single load wheel to three load wheels, the amount of subsidence on soft road conditions decreased by about 35%.
