摘要

摘要: 运用多体动力学方法，建立了6对负重轮履带车辆21自由度带动力传动悬置系统的整车模型。并结合简化坡道模型，仿真研究了该型车辆在不同冲坡工况下发生悬挂击穿的规律。研究发现：在不同纵向偏驶角下，发生悬挂击穿的临界车速呈"W"型，且悬挂击穿都最先发生在第一对轮的先上坡侧。同时，随着坡角的增加，最小悬挂击穿临界车速迅速减小，发生击穿对应的纵向偏驶角则增大；悬挂击穿发生后，车体前部所受的冲击迅速增大。

Abstract: A 21-DOF model of the tracked vehicle with 6 pairs of wheels including power-transmission system was built based on the multi-body dynamics method. Combined with a simplified slope model, rules of suspension breakdown during different slope conditions were studied by simulations. Results showed that the critical speed of vehicle occurring suspension breakdown is a "W" curve with different slope-vehicle angles, and one of the first pair of suspension always break down at first. When the slope angle being bigger, the minimum of critical speed of suspension breakdown decreases quickly and its corresponding slope-vehicle angle increases. Moreover, impacts on the front of vehicle body influencing by suspension breakdown increase greatly.
