The optimal design of the submarine pressure-resistant cylindrical shell is studied with the structural target reliability as the constraint condition. The design variables and the corresponding failure modes of the structure are determined according to the structure of the submarine’s pressure-resistant cylindrical shell. The optimization objectives and the related constraints are established when the structure is optimized. The reliability constraint considers the strength and stability failure of the submarine’s pressure-resistant cylindrical shell System reliability. The corresponding calculation formulas are deduced and the computer programs that can be used in engineering practice are compiled. The optimization design and analysis are carried out with a concrete example to provide a theoretical basis for the reliability design of submarine structures.
