Abstract

Underwater vehicles have been recognized as a key strategic asset due to the increasing uncertainty of international situations and national security. For their design and construction, it is necessary to develop preliminary design approaches to determine the volumes and longitudinal locations of the tanks while considering the minimum design requirements. A multi-objective optimization technique was applied for optimization of the volumes and longitudinal locations. A concept desgn procedure was constructed to determine volumes and longitudinal locations of trim and compensation tanks. The feasibility of designed tanks was assessed after verifying in-house code for evaluating the trim-compensation polygon. The design variables, constraints, and objective functions were formulated to define an optimization problem using NSGA-Ⅱ. The feasibility of the constructed approach was reviewed through a comparative study considering different constraints. The applicability of the constructed approach was confirmed by investigating the effect of requested number of trim and compensation tanks.

基于非支配排序遗传算法的水下航行器调节和补偿水箱体积和纵向位置优化Ⅱ

由于国际形势和国家安全的不确定性日益增加，水下航行器已被公认为一种关键的战略资产。对于储罐的设计和建造，有必要制定初步设计方法，以确定储罐的体积和纵向位置，同时考虑最低设计要求。采用多目标优化技术对体积和纵向位置进行优化。建立了一个概念设计程序，以确定调节罐和补偿罐的体积和纵向位置。在验证了内部编制的计算补偿多边形的代码后，对所设计的储罐的可行性进行了评估。利用NSGA-Ⅱ建立了设计变量、约束条件和目标函数来定义优化问题。通过考虑不同约束条件的对比研究，对所构建方法的可行性进行了论证。通过对所要求的调平舱和补偿舱数量的影响进行研究，证实了所构建方法的适用性。
