| Abstract: | According to the theory of curve beam and elastic foundation beam, a mechanic model for the structure of a special submarine cabin is developed. The circumferential stress of the middle plate of the pressure-hull shell is given by using energy method. The differential equation of the ring-stiffened shell is built and solved according to the boundary condition, and the stress calculation method for the ring varied stiffened cylindrical shell is obtained. The validity of the calculation method is validated by theoretical analysis and model testing. This calculation method can be adopted when the current criterion is revised. |
