履带车辆电驱动系统小半径转向计算研究

Numerical Reseach on Small Radius Steering of Tracked Vehicles' Electric Drive System

讨论了履带车辆小半径转向的特点,进行了转向理论分析及转向功率分配和牵引计算.不同行驶路况下转向的仿真计算和分析表明,履带车辆电驱动系统在输出功率足够的情况下,可以通过单独控制内外侧牵引电机的输出转速实现所需半径转向.研究结果对设计履带车辆电驱动系统具有指导意义.

The steering characteristics in small radius for a fracked vehicle are discussed .The steering theory is analysed,and the steering power distribution and traction calculation are also carried out. By computer simulation on steering with given variant road conditions,it can be seen that a tracked vehicle with electric drive system can steer in small radius through controlling the output rotate speed of the inside and outside tractive motor respectively. The presented method is proved to be useful to guide the vehicle design mentioned above.
