摘要

摘要: 潜水器的质量大小直接影响其性能，设计时要求潜水器在满足强度、刚度等要求的前提下，要尽可能减小其质量。应用正交试验的方法来实现潜水器耐压壳体结构的优化，但用正交试验方法处理约束问题比较复杂。因此将以质量最小化为目标和以强度要求为约束条件的优化设计问题转化为无约束多目标的优化设计问题。得出各个参数对壳体的强度和质量的影响规律，最后运用综合平衡法得出最优的设计方案。

Abstract: The mass of the underwater vehicle affects its overall performance directly. So after meeting the requirements of strength and stiffness, the mass of submersible should be reduced as much as possible. In this paper, based on orthogonal test method, we achieve the structural optimization of the submersible pressure hull. Because it is more complicated to deal with the constraints by orthogonal test, so the structural optimization problem for the underwater vehicle based on the constraints of strength, stiffness and minimum mass was converted into a multi-objective optimization problem without constraints. By analyzing the test results,we obtained the influence law of each parameter on the strength and weight of the shell. Finally, after the comprehensive consideration, we give the optimal design scheme of the submersible pressure hull.
