履带车辆转向性能指标分析及实验研究

转向性能是评价履带车辆机动性的重要指标之一.文中针对转向角速度、转向半径和转向消耗功率3个指标,分别在不考虑履带滑转滑移的理想条件下和考虑履带滑转滑移的实际情况下,对履带车辆的转向性能进行了讨论和分析,对2种条件下履带车辆的转向性能的变化进行了比较.为了对履带车辆在转向过程中履带的滑转和滑移程度进行定量的分析,定义了履带的滑转和滑移系数.通过实车实验,对分析结果进行了验证.

Indexes Analysis and Experimental Research on the Steering Performance of Tracked Vehicles

The steering performance is one of the important indexes to evaluate the mobility of tracked vehicles. In this paper, the steering performance of tracked vehicle is analyzed under two different conditions. One is an ideal condition, under which the vehicle is steering without skid and slip of tracks. The other one is a real condition, under which the vehicle is steering with skid and slip of tracks. And three indexes of steering performance: the angular speed of steering, the turning radius and the power of steering, are analyzed. The steering performances in different conditions are compared. In the experiments of a tracked vehicle, the result is validated.
