摘要
在驾驶员 四轮转向汽车闭环操纵系统动力学模型的基础上 ,应用非对称特征值问题的矩阵摄动理论 ,给出驾驶员 四轮转向汽车闭环操纵系统运动稳定性对汽车结构参数和四轮转向系统控制参数的灵敏度和多个参数同时变化时的摄动量 ,并与前轮转向汽车的结果进行了比较。仿真结果表明 。
The sensitivities and perturbation amount of vehicle motion stability were analyzed when several parameters of the vehicle varied simultaneously. The analysis is based on the model of driver vehicle with 4WS closed loop system and the nonsymmetrical matrix perturbation method. Some inherent relations of motion stability were revealed quantitatively for vehicle with 4WS and vehicle with front wheel steering system by simulation examples. The results show that the present method can direct the selection of vehicle design parameters, thus the handling and stability of vehicle can be enhanced.
