潜艇耐压结构的稳定性分析

Stability Analyses on Pressure Structure of Submarine

系统地讨论了环肋圆柱壳、环肋圆锥壳、锥—柱结合壳以及耐压液舱等结构的稳定性问题。通过大量有限元计算和理论分析 ,指出了有的解析法公式可用 ,有的要作修正 ,有的需要进一步探讨 ,有的给出了计算方法的具体建议 ,使正确理解和使用各种稳定性解析公式成为可能。

The stabilities of some submarine structures are discussed. These structures include ring stiffened cylindrical shell,ring stiffened conical shell,conic cylindrical hull,pressure tank and so on. Through a great number of finite element calculations, this paper points out that some analytical methods can be used directly, while some others must be modified in advance,and some methods need farther discussions.Some concrete proposals are also given, so that the user can understand and apply those diversified analytical formulas of stability correctly. This paper has important theoretical and engineering values.
