| Abstract: | 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. |
