摘要
橡胶有限元分析是橡胶元件设计开发的现代分析方法,目前在汽车工程上应用较多。本文系统阐述了橡胶有限元分析的理论难点、解决方法及注意事项,涉及结构非线性的考虑、体积完全或几乎不可压缩超弹性本购模型的选择、材料试验方案及数据拟合、基于约束变分原理的混合有限元格式、基于线性黏弹性的应力松弛试验、单元选择原则以及非线性求解控制等诸多方面,以期对橡胶悬置的有限元分析有一个全面的总结和指导作用。
Finite element analysis （FEA） is an advanced method for development and design of automotive rubber components. The theoretical difficulties and the corresponding methods to overcome these difficulties are discussed systematically, including the issues such as the geometric nonlinearities, the incompressible or nearly incompressible rubber constitutive laws,the material test methods and test data fitting, the mixed u-p formulation elements based on constraint variation principle, the stress relaxation test for visco-hypoelasticity material model, the selection of the element types and the solution control for highly nonlinear problem. The results given in this paper will be helpful for FEA of automotive rubber mount.
