| 摘 要： | 采用二自由度1/4车辆模型对汽车悬架进行了建模分析。首先建立了微分方程和状态空间模型,其次使用了频域响应法和拉氏变换法分析了模型,并绘制了二者的频率响应曲线图,验证了模型的准确性。这为后续的位移、速度、加速度和力反馈控制奠定了数学模型基础。

| Abstract: | With 2 DOF(degree of freedom) quarter car model,automotive suspension is modeled to simulate in this research.First differential equation and state space model are built,then the model is analyzed by frequency response and Laplace transform.Finally the frequency response figure is drew.The results show the model is correct,which can provide the mathematical model basis for subsequent displacement,velocity,acceleration and force feedback control. |
