Calculation Method of Pressure Tank Structure with Solid Floor

应用弹性力学经典理论和求解环肋柱壳的传统方法，将耐压液舱结构的几种结构形式综合成统一的力学模型，进行整体求解，获得各应力解析表达式；提出了液舱区耐压船体壳板极限承载能力及波舱壳板失稳压力的计算方法。力学模型清晰合理，求解简便，计算结果符合实际，可应用于工程设计。

A unified mechanical model for various pressure tank structures of submarines is developed in this paper based on the classic mechanics of elasticity and general solution of the ring-stiffened cylindrical shell. The analytical expression of stress is obtained by solving the unified equations. A rational method is presented for calculating the ultimate strength of the pressure hull plate and the buckling load of the tank shell. The rationality and simplicity of present method have been verified by model experiments. It can be easily applied to the design of submarine pressure tank structure.
