潜艇耐压结构全船有限元应力分析

Finite Element Stress Analyses on All Pressure Structure of Submarine

在对潜艇全船耐压结构有限元应力分析的基础上 ,又进行了各局部结构的二级甚至三级离散有限元应力分析 ,比较了一般环肋圆柱壳、环肋圆锥壳、环肋锥 -柱结合壳、横舱壁区域结构、耐压液舱区域结构典型点应力与现有解析算法结果的差异程度 。

Finite element stress analyses are done on all pressure structure of submarine On this foundation, we are also done stress analyses on local structures in second level even third level discrete Then, are give a comparison of the finite element results with those from analytical methods existed to find out how different it is The comparison includes the stresses of the representative points from a ring stiffened cylindrical shell, a ring stiffened conical shell, a conic cylindrical hull, a transverse bulkhead structure and a pressure tank structure At last, are got some conclusions to practical engineering use
