| 摘 要： | 对四轮转向系统建立一个五自由度车辆非线性动力学模型,并进行仿真分析,与现有的4W S模型进行比较,以证明其能更好地反映车辆实际的动力学响应。用"牛顿力学"理论来建立平衡方程,物理运动分析也较为完善,并进行了精确的仿真,对建立汽车四轮转向模型来说无疑是一个突破,不仅能对汽车各个方向的运动建立严密的平衡方程式,仿真结果也更为准确,有利于更进一步地对汽车动力学运动进行分析。

| Abstract: | The paper establishes a five-degree-freedom 4WS nonlinear dynamics vehicle model,then analyzes it and compares with other models which have been established for proving the better dynamics response of it.It is a breakthrough for establishing 4WS model with the theory of "Newton Mechanics",the perfect physical analysis,which can not only establish detailed equations for each direction of motion,but also can get more accurate simulated results.It is of advantage for further research. |
