摘 要: 基于遗传算法的多目标空间区域内的探索性全局优化技术,将阻力系数、丰满度与最大减压系数发生位置作为综合判定指标,在解决UUV线型优化的过程中,引入集成优化框架,对UUV外形进行多目标优化设计;建立了UUV外形优化的一体化模型,针对UUV外形优化设计的要求,对外形设计进行参数化,提出设计变量的选取原则,并针对具体算例进行仿真优化设计,优化计算结果表明:该优化设计方法有效地改善了UUV的阻力性能和压力分布,阻力减小大约4%,在工程应用中是可行的,为目前UUV外形优化设计提供了一个完整的方法。 Based on the genetic algorithm optimization technic of global searching in the multi--objective domain, employ the UUV fullness, resistance coefficient and maximum decompression factor as the goal function, in the process, introduce integrative optimization frame to search the optimization UUV shape, a integrative UUV shape optimization design model is built, according to the need of optimizing the UUV shape, how to choose the shape parameters and design variables is described. Specific case of optimizing shape has been done, and the result shows that: the method is feasible, it can improve the resistance characteristic and the distributing of pressure, reduce drag force on 4%, provide a unabridged method for the shape optimization design of UUV.
