反应釜局部结构的有限元应力分析

Stress Analysis of Part of Reaction Vessel with Finite Element Program

对反应釜局部结构（高颈整体法兰及连接部分）进行了结构分析、受载分析和有限元应力分析，绘出了分析件内外表面的应力分布，讨论了法兰厚度对应力的影响等。

The structure of the Part of reaction Vessel and Their loads andstresses are analysed by the finite element program in this paper. The stressesdistribution on internal and outer surface are drawn,the effect of flange thicknesson stress are discussed.
