摘　　要：液压减振器在铁路机车车辆上被看成是一个减振器(阻尼)和端部橡胶元件(刚度)相串联的组合部件,串联刚度对机车车辆动力性能有着较大的影响。文章讨论了串联刚度对减振器特性的影响,还介绍了减振器性能的测试方法和动力学计算中的减振器模型。The hydraulic damper is regarded as a composite part of a damper(damping) in series connection with an end rubber element(stiffness).The series stiffness has fairly big effect on the dynamic performance of locomotive and rolling stock.In this paper,the effect of series stiffness on features of hydraulic dampers is discussed,and the measurement method for the performance of dampers and the model of dampers in dynamics calculation are described.
