摘　　要：为了研究橡胶密封圈在刚性力作用下的应力与变形,采用Newton-Raphson非线性算法,使用位移准则来判断其收敛性。密封圈则按照超弹性材料处理,采用了Mooney-Rivilin模型材料,建立其有限元模型,进行了网格的划分,施加了合适的边界条件,模拟了真实的受力环境,计算出了在刚性力作用下产生的应力和发生的变形。并且使用动画技术直观地显示了其变形过程。应变有限元分析的结果为橡胶材料可靠设计、优化提供了一定的指导。In order to research the stress and deformation of rubber seal ring under rigid forees, Newton-Raph- son nonlinear algorithm is adopted and used displacement criterion to judge the convergence of the algorithm. Rubber seal ring is regarded as hype elastic material of Mooney-Rivilin mode. The finite element model of it is created and the mesh is generated and appropriate boundary conditions are applied, then the stress and defirmation are calculated. The rest, h is displayed by animation technology. Those conclusions afford benefit for reliable design and optimization of nber material.
