摘　　要：针对双筒液力减振器的内部阀系结构,借助于ADAMS/Hydraulics模块,搭建其参数化和功能化的虚拟样机,进行了阻尼特性的仿真计算与试验验证。在此基础上进行二次开发,使之能够通过操作界面方便地设置阀系设计参数,快速自动地完成减振器建模、仿真与调试。结果表明,该方法能够缩短开发周期,减少样件试制和试验成本,提高产品的系统级性能。Based on the inner valves structure of the hydraulic shock absorber（HSA）,the parameterized and functionalized virtual prototype was built using MSC.ADAMS/Hydraulics,and the HSA damping characteristic simulation and model validation had been completed according to the bench test.On this basis,the redevelopment was carried out to set up parameters and simulate HSA characteristics quickly and automatically.The results show that the method can shorten the development cycle,reduce the sample trial and test costs,and improve the system-level performance of HSA.
