摘　　要：介绍了橡胶减振器Mooney-Rivlin本构关系描述的橡胶材料的非线性弹性特性。通过有限元模型的建立,对减振器静态刚度特性和动态刚度特性进行了研究,得出了减振器刚度失效判据和硬度失效判据。Nonlinear elasticity properties of rubber material described by Mooney-Rivlin constitution relationship of rubber isolator are introduced. The static and dynamic stiffness characteristics of the isolator are analyzed by establishment of fiinite element model ,for the rubber isolator. The stiffihess and hardness failure criteria of the rubber isolator are concluded.
