反应釜人孔结构的三维有限元分析

Three Dimensions Limited Element Analysis of the Manhole Structure at Reactor Bank

在反应釜的封头上开设大孔径的人孔,造成开孔附近区域有很大的应力集中,必须进行补强。本文在常规设计的基础上,考虑到开孔附近应力集中部位的安全性,运用ANSYS软件进行三维有限元分析,验证人孔结构的安全性。

In the reactor head with a large aperture opening manhole,Resulting in a great area near hole stress concentration,Must be reinforced.In this paper,on the basis of conventional design.Taking into account the stress concentration near the hole security,Using ANSYS finite element analysis software,Verify the security of the manhole structure.
