考虑垫片非线性时法兰接头性能的三维有限元模拟——法兰接头的应力强度和泄漏过程分析

3-D Finite Element Simulation of Bolted Flange Joint Lonsidering Gasket Nonlinearity——Analysis of Stress Intensity and Leakage Process of Bolted Flange Joint

本文对法兰接头系统建立了有限元模型。利用ANSYS有限元程序 ,详细分析了法兰接头连接系统的强度和紧密性 ,同时分析了接头的泄漏过程。

With the bolted flange joint taken as a whole system, the influences of different factors on stress distribution system integrity and tightness,and the leakage process of the bolted flange joint were studied in this paper。
