In order to improve the structural performance of the multiple openings pressure cylinder shell of manned submersible, the initial scheme was analyzed by ABAQUS software, the parametric analysis process of multi openings pressure cylinder shell was designed, the optimal Latin hypercube method was used to select and analyze the samples in the design space, the influence of the design variables on the response was analyzed, and the approximate model of multiple openings pressure cylinder shell with higher fitting accuracy was established. Taking the mass and ultimate strength of pressure cylinder shell as the objective function, the multi-objective optimization model of multiple opening pressure cylinder shell was established based on the constructed approximate model, and to solve by using the second generation of non dominated sorting genetic algorithm. The results show that the solution in Pareto solution set is optimized on some indexes, but the optimization aspects and degrees are different, which provide basis for selecting the optimization scheme of multiple opening pressure cylindrical shell.
