Abstract: Based on complex mechanical properties of nonmetallic materials in a rubber vibration isolator, the two-parameter constitutive model of rubber material is studied, and the parameters are fitted. The dynamic and static calculation model of vibration isolator is established by finite element software. Then the calculation model are verified by experiments. The results indicate that the calculated results of static deformation and inherent frequency of the vibration isolator are in good agreement with those of the experiments, and that the relative error is less than 10%. The calculation accuracy of this model is proved to be high, which can lay a foundation for the design of vibration isolators with nonmetallic materials in different fields.
