摘要
汽车悬架系统是汽车研究与设计中的重要内容,因为汽车悬架系统的性能优劣直接影响乘客乘车的舒适度。主要通过分析汽车悬架系统,对其进行简化,并建立1/4模型,然后根据牛顿第二定律得到系统的运动方程,在运动方程的基础上通过MATLAB/Simulink对简化模型进行仿真,得到车身振动加速度曲线和功率谱曲线,对以后汽车悬架系统的分析设计有着重要的意义。
The automobile suspension system is an important content in the research and design of automobile,because the performance of automobile suspension system directly affects the passenger comfort.In this paper,the vehicle suspension system is analyzed and simplified,and the model of 1/4suspension system is set up;then according to the Newton＇s second law,the motion equations of the system is established;based on the equations of motion,the simplified model is simulated by use of MATLAB/Simulink,and the acceleration curve and the power spectrum curve are obtained.This work has important significance for later analysis and design of the automobile suspension system.
