摘要：针对汽车减振器特性的研究，提出了一种新的研究手段,利用ADAMS和EASY5软件分别建立了汽车减振器的虚拟样机模型和液压模型,并在此基础上进行了联合仿真,把仿真结果与试验结果数据进行了对比。经过验证证明，联合仿真结果与台架试验结果具有良好的一致性,通过仿真可以有效地预测减振器的性能，并达到了缩短减振器研制周期和降低研制成本的目的。

Abstract: A new method was proposed in the study of vehicle shock absorbers using ADAMS and EASY5.The virtual prototype model and the hydraulic model was established respectively, and the cosimulation was conducted on the basis of the two models. Results of the cosimulation and the experiment were compared to validate its coinherence. The performance of the damper can be predicted effectively and would shorten the period of research and development as well as lower its cost.
