In this paper,the arch-waist flexible chassis was taken as the research object,and its traction characteristics in soft soil environment were deeply analyzed by establishing the crawler component model.The relationship model between pitch angle and traction force of crawler components was solved,and the bearing capacity of bottom soil was analyzed by DEM-MBD two-way coupling simulation method,and then the traction force law of crawler at different pitch angles was obtained,which can provide some reference for the research of agricultural power chassis suitable for hilly and mountainous areas.
