摘　　要：采用有限元法模拟了垫片的非线性特性,计算了垫片应力及法兰应力。按应力分析设计方法校核法兰;基于PVRC紧密性的计算方法,以垫片应力为判据,关联了外弯矩与接头紧密度之间的关系。The non - linearity of the gasket material was simulated, and the gasket stress and flange stress were computed with the 3D FEM in this paper. The analytical design method is used to check the flange intensity. According to the gasket stress, the external bending moments and the tightness of flanged joint are related based on the tightness calculating method of PVRC.
