橡胶隔振器大变形有限元分析

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。

A Large Deformation Finite Element Analysis of Rubber Isolator

The finite element analyses of deformation of rubber isolator in tensile, compression and shear and torsion were performed using hyperelastic constitutive model. The finite element modeling techniques for incompressible deformation of rubber was discussed in this study as well. The analysis also focused on the deformation models of rubber structures at various loading conditions and material test data that the FEA need. Compared with experimental results, the best type of material test data for filling the constitutive model of rubber isolator under three different conditions was obtained, which provided a good reference for the numerical simulation of rubber structure.
