摘　　要：采用半主动隔振系统可以有效衰减低频振动,降低振动物体的振动幅值。半主动减振器是半主动悬挂系统中的核心部件。根据流体力学理论和多体力学理论,按照半主动减振器的本构关系,建立了半主动减振器的仿真模型。通过数值仿真的方法研究了半主动减振器的出力特性,给出了半主动减振器的耗能曲线,并分析了影响半主动减振器性能的主要影响因素及其影响规律。The vibration can be suppressed by the semi-active isolation vibration system. The semi-active damper is the core of the semi-active suspension system. The model of the semi-active damper is build according to the theory of hydromechanics and dynamics of multibody systems and the constitutive relation of the damper. The force characteristic of damper is studied with the simulation method. The energy consumption curve of the semi-active damper is shown. The influencing factor of damper quality and the Influence rules is analyzed
