【 摘 要 】

The comprehensive optimization design of UUV structure is of great significance to improve the overall performance of the vehicle. In this paper, the mathematical model of the optimization problem of the ring-stiffened cylindrical shell is established under the constraints of the stability and strength, and the multi-objective optimization is carried out with the multi-objective genetic algorithm (MOGA). According to the Pareto solution, the MADM is studied by using the ranking method of TOPSIS, and then the comprehensive ranking of the Pareto optimal solution is obtained. The method of this paper has important engineering guidance for the optimization design of shell structure and the similar engineering practice.
