摘要:: 为探究某型橡胶隔振垫的安装预压缩量与刚度的关系，建立了隔振垫在不同预压缩量条件下的静刚度模型。通过商业有限元软件，选用Mooney-Rivlin超弹性本构模型，分析了橡胶隔振垫在不同压缩量的条件下的各向刚度。结果表面，该结构形式的隔振垫，其压缩量对垂向刚度的变化较为敏感，对径向和切向两方向的刚度变化影响不大。通过试验进一步验证了该有限元计算方法的结论，因此该计算方法对隔振垫的选型和使用具有一定的指导意义。

Abstract:: In order to investigate the relationship between the installation pre compression shrinkage and stiffness of a certain type of rubber isolation pad, a static stiffness model of the isolation pad was established under different pre compression shrinkage conditions. Using commercial finite element software and Mooney-Rivlin hyperelastic material constitutive model, the isotropic stiffness of rubber vibration isolation pad under different compression was analyzed. The results indicate that the compression of the vibration isolation pad in this structural form is more sensitive to changes in vertical stiffness, and has little effect on changes in stiffness in both radial and tangential directions. The conclusion of the finite element calculation method is further verified through experiments, so this calculation method has certain guiding significance for the selection and use of vibration isolation pads.
