摘　　要：本文在消化吸收国内外潜艇长舱段结构强度和稳定性研究方法的基础上,总结出长舱段的总体失稳波形和计算方法,在此基础上应用有限元方法对长舱段结构强度和总体稳定性进行数值分析研究,揭示了长舱段结构的力学特性、结构强度和稳定性分布规律等。文中还根据总体失稳压力-框架肋骨惯性矩变化关系曲线搜索框架肋骨最优截面刚度参数,为框架肋骨结构参数选取提供技术参考。Based on absorbing and analyzing the method of calculating the strength and stability of submarine long compartments,this paper summarizes the shapes of instability and its theory methods.According to these theory,this paper performs a series of finite element analysis on the strength and general stability of long compartments to expose its mechanical characteristics and rules.In term of the relationship curves of general stability-inertia moment of heavy frame,we can search out the optimum parameters of the heavy frame.The results and conclusions can be referred by designers.
