摘　　要：针对履带喷雾车软路面上越障能力差的特点,理论分析了喷雾车在平地和坡道上的跨越壕沟和攀越垂直壁的性能,并采用多体动力学软件Recur Dyn在粘土软地面条件下对履带喷雾车的越障性能进行了仿真验证,从而证明了理论分析结果的合理性,同时分析了重心位置和行驶速度对车辆攀越垂直壁能力的影响,结果认为喷雾车的重心位置沿纵向前后偏移0.1m对其攀越垂直壁能力的影响最小,喷雾车以车速1.0km/h攀越垂直壁时,行驶稳定性最好。研究结果为进一步改善履带喷雾车的越障性能提供了设计依据。For the poor ability of crossing obstacle on soft terrain for tracked spraying vehicles,the performance of crossing trenches and climbing vertical walls on the flat ground and the slope are analyzed theoretically,and then climbing obstacle ability on soft clay ground is simulated and verified in Recur Dyn,which proves the rationality of the theoretical results.Meanwhile,the effects of the gravity center position and driving speed on the ability of climbing vertical walls are analyzed. It can be concluded that the driving stability would be best when the tracked spraying vehicle climbs vertical walls at 1.0km/h;the gravity center of the vehicle front and rear offsets 0.1m along the longitudinal direction,which has least effect on the ability of climbing vertical walls. The research results would provide a design reference for further improving the performance of crossing obstacle for tracked spraying vehicles.
