摘要
海绵橡胶是密封条的重要组成部分 ,是一种可压缩的大变形非线性弹性材料。材料的本构模型是进行CAE分析的关键 ,为此 ,在Ogden不可压缩应变能函数的基础上 ,利用连续介质力学理论 ,推导了可压缩海绵橡胶材料的应变能密度函数。经过实际算例和试验验证 。
Sponge rubber, which the seal is made up of, is a large deformation nonlinear elastic material. Constitutive model of the material is a key to CAE (Computer Aided Engineering). Using the theory of continuum mechanics, strain energy density function of sponge rubber material is founded based on Ogden model. A lot of results of calculation and experiments show that this model can reflect material characteristics of sponge rubber.
