某汽车悬架系统性能分析及参数优化
摘 要
分析当前轿车的悬架系统，对之进行简化。首先建立其1/4模型，利用仿真软件MATLAB里面的附件Simulink对悬架的简化模型进行仿真，考察其加速度，输出位移等特性。在此基础上进一步建立悬架系统的1/2模型，继续考察车身的加速度，输出位移，转角等系列特性。Simulink软件在整个的仿真过程中显示出强大的能力。

Abstract
Analyze the suspension system of modern car, and then simplify it. First the model was analyzed with 2 degrees of freedom by the software simulink. Based on this, and then building 12 degrees of the suspension system. Inspect the acceleration and rotation angle and some other characters. In the whole process, the software simulink displayed powerful capacity.
Keywords: car suspension, semi – active control, simulation
