摘要:

在对静液驱动履带车辆转向行驶理论分析的基础上,运用MATLAB/Simulink对系统转向过程进行了仿真分析。结果表明:在三种转向工况中,原位转向时车辆所需总功率、马达负载转矩及系统压力均最大,宜采用独立式转向;小半径转向时采用独立式转向可保证驾驶员在转向操纵过程中车辆完成转向的情况下,通过踩加速踏板提高平均车速来提高车辆机动性能;修正转向时采用差速式转向可使系统具有良好动态特性。

Abstract:

The steering simulation was conducted by using MATLAB/Simulink on the basis of analyzing the steering process of a hydrostatic drive tracked vehicle. Total power the vehicle consumes, motor load torque and system pressure in in-situ steering are all the maximal in three steering conditions.Independent steering is to be adopted in small radius steering, which can make the driver step accelerator pedal to increase average speed and improve vehicle mobility in the case of completing the steering. Differential steering is to be adopted in modified steering, which provides excellent system dynamic characteristics.
