摘　　要：建立了半主动悬架汽车1/4动力学仿真模型,用谐波叠加法构成的路面不平度作为路面激励,利用Matlab/Simulink软件,对某一车型数据进行了动力学仿真和分析,仿真输出量可作为评价半主动悬架的控制方法和有关平顺性结构参数的依据。The dynamic equations and simulation model of quarter vehicle of semi-active suspension is established, successively, making use of partial wave adding model to build the model of road roughness as the excitation of ground and using Matlab/Simulink software, the dynamic simulation and analysis according to some actual data is realized. Simulation output can be used to evaluate thecontrol method of semi-active suspension andstructure parameters of vehicle in relation to ride performance.
