摘要
本文采用三角形轴对称应力计算程序,对于球壳开大孔问题,进行有限元计算,给出设计内压下应力和位移的等值线圈,贮罐人孔封头的有限元计算结果,为球壳强度评定提供依据。
In this paper,the stress and displacement of a spherical shell with big hole is calculated by the use of a finite clement program which suits for friangle axisymmctrical stress.As the resule the contours of scress and displacement near closurehead of man hole are obtained.The result can be used as the basis of the judgement for strength of spherical shell.
