围壁补强的圆柱壳开孔结构有限元分析

摘要

The single radial opening is common on the pressure hull of submarine , and is stiffened by coaming usually .The ABAQUS software was utilized to calculate the stresses of cylindrical shell cut with single radial opening .The stress components were separated according to the equivalent principles to study the influence of coaming parameters upon stresses distribution , such as opening rate , thickness and height of coaming .%考虑到潜艇耐压壳上不可避免地要设置一些正交单圆孔，并采用围壁进行补强，利用ABAQUS通用有限元软件对该结构形式的系列模型进行求解，并利用等效原理分离出各应力成分，最终得出开孔率、围壁厚度、围壁高度以及围壁在壳体外的比例对各应力成分的影响规律。
