摘要
本文针对潜艇普通环肋圆柱壳结构设计的特点，建立了潜艇普通环肋圆柱壳结构尺寸优化的数学模型，并考虑到在该结构设计中存在的不确定因素，进行了结构的模糊优化设计。采用约束非线性混合离散变量优化方法，直接获得离散变量的最优解，无需作规格化处理。算例表明本文方法简便实用。
In consideration of the design features of circular stiffened cylindrical shell structures for submarine,the mathematical model of fuzzy optimum design for the structures with fuzzy uncertainties is built.The MDOD method is used,the normalized dispersed optimal solution are obtained,and the normalized processing is not necessary.Some practical examples indicate that the method presented in this paper is better than the former.
