橡胶密封圈在刚性力作用下应变有限元分析

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。

FEM Analysis of Strain of Rubber Seal Ring under Rigid Forces

In order to research the stress and deformation of rubber seal ring under rigid forces, the paper adopts Newton-Raphson nonlinear algorithm and uses displacement criterion to judge the convergence of the algorithm. In this paper, 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 deformation is calculated. The result is displayed by animation technology. Those conclusions afford benefit for reliable design and optimization of rubber material.
