摘　　要：以橡胶隔振器为研究对象,基于超弹性本构模型,对拉伸、压缩、剪切状态下分别进行有限元计算,探讨橡胶等不可压缩材料大变形有限元建模技术;重点研究橡胶结构不同受载方式下变形模式及有限元分析所需要的材料试验数据。经与试验结果对比分析,得到隔振器三种状态下,填充超弹本构模型最优的材料数据类型,为橡胶结构件的数值模拟提供有益参考。The tensile, compression and shear deformations of rubber isolator were studied by FEA, using hyperelastic constitutive model. The finite element modeling technique for incompressible deformation of rubber was discussed as well. The analysis focuses on the deformation modes of rubber structures under various loading conditions and also on the material test data that FEA needs. Comparing with experimental results, the best type of material test data for fitting the constitutive model of rubber isolator under three different conditions was obtained, which provids a good reference to the numerical simulation of rubber structure.
