核级阀门中法兰应力分析

Flange Stress Analysis of the Nuclear Grade Valve

基于有限元软件分析方法及理论计算方法对阀体中法兰应力进行校核和评估,经对计算结果对比,定量分析出两种计算结果与许用应力的关系,以便于优化阀门中法兰设计。

Based on finite element software analysis method and the theory calculation method, checking and evaluation for the flange stress in the body are conducted, by comparing the results of the calcula- tion ,two kinds of relationship between the calculation results and the allowable stress are given by quantitative analysis which optimize the valve flange design.
