摘要
建立了两轴转向特种车辆的三自由度动力学模型,得到车辆转向性能评价参数与前轮转角之间的传递函数。通过建立的ADAMS虚拟样机模型,进行车辆的虚拟试验,验证了数学模型的正确性。对模型进行阶跃响应分析,针对高速行驶时车辆转向的不平稳性,对影响车辆转向性能的结构参数进行改进,得出对车辆转向性能有改善作用的结构尺寸范围。
The 3 degree-of-freedom dynamics model of Special Double-axle Steering Vehicle was established and the transfer function between evaluation parameters and the front wheel angle was obtained. The virtual experiment of the vehicle was done by ADAMS( Automatic Dynamics Analysis of Mechanical Systems) model,the mathematical model was verified. The step response of the vehicle was analyzed to optimize the steering performance by improving the structure,and the reasonable range of the structure size was obtained.
