- The mechanical property of collective escape capsule of pressure hull in deep-sea environment is studied In the engineering examples of new type of variable thickness escape capsule the different thickness of the displacement, stress distribution and its regularity of distribution of mechanical stress maximum position of the hull is obtained by finite element analysis. The results show that vertical deformation of capsule turns out to be the major deformation under hydrostatic pressure and the overall deformation is relatively small the stiffness of pressure hull satisfies the requirement. The stress of capsule are dominated by vertical and shear stress Vertical stress is given priority to tensile stress and its value at a higher level while shear stress is mainly compressive stress. By analyzing the stress distribution rule all the stress meet the safety requirements. In this paper, The calculation method and simulation results in this paper could provide the reference for both optimization design and structure reliability assessment of collective escape capsule.
