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。
攷慮到潛艇耐壓殼上不可避免地要設置一些正交單圓孔,併採用圍壁進行補彊,利用ABAQUS通用有限元軟件對該結構形式的繫列模型進行求解,併利用等效原理分離齣各應力成分,最終得齣開孔率、圍壁厚度、圍壁高度以及圍壁在殼體外的比例對各應力成分的影響規律。

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 .
