摘　　要：金属橡胶隔振器在工作的时候,由于金属丝不仅仅存在弹性变形,而且其间还存在着干摩擦及扭转变形,此作用机理导致了金属橡胶隔振器的减振系统为非线性特性。首先从阻尼力及弹性力两部分建立减振系统的数学模型,其间采用了多尺度法对其非线性特性进行了分析,推导出了非线性隔振系统的激励频率与响应振幅的关系式。与一般线性系统响应特性对比,得出了非线性隔振系统的响应特性。As the metal rubber absorber works, it exists not only the elastic deformation, but also the dry fiction and torsional deformation between the metal wires, which leads to the nonlinear characteristics of the metal rubber absorlDer isolation system. First, the matJiematical model considering the damping force and elastic force was con-structed. Then, the multi-scale metJiod was used to analysis and deduce the matJiematicacitation frequency and resjoonse amplitude. Comparing wit!i the linear system characteristic, the conclusion was ob-tained about the response characteristic of the nonlinear isolation.
