Abstract

This study addresses the shape optimization of underwater vehicles and proposes a design optimization scheme for the Myring-style shape by incorporating direct sailing resistance and flow-induced noise. Numerical simulation methods for the resistance and flow-induced noise are established, and their effectiveness is validated. Integrating CATIA and STAR-CCM+ within the modeFRONTIER platform enables the parametric design of the Myring-style shape,and the calculation of flow-induced noise was accomplished through the automated analysis based on resistance. Representative surrogate models are tested and compared; high-accuracy models for resistance and flow-induced noise are consequently identified. A multi-objective optimization model based on the Kriging framework is then constructed for the Myring-style shape. Using the nondominated sorting genetic algorithm II, multi-objective optimization is performed. Comparative results indicate that relative to the initial design, the Pareto front solutions are improved for some objectives, with certain solutions achieving enhancements across all objectives, thereby validating the effectiveness of the proposed optimization process.

考虑直接航行阻力和流致噪声的默林式形状多目标优化

本研究针对水下航行器的外形优化问题，提出了一种考虑直接航行阻力和流致噪声的默林式外形设计优化方案。建立了阻力和流致噪声的数值模拟方法，并验证了其有效性。在modelfrontier平台中集成CATIA和STAR-CCM+，实现了默林式外形的参数化设计，并通过基于阻力的自动化分析完成了流致噪声的计算。对代表性代理模型进行了测试和比较；从而确定了阻力和流动噪声的高精度模型。在此基础上，建立了基于Kriging框架的多目标优化模型。采用非支配排序遗传算法II进行多目标优化。对比结果表明，相对于初始设计，Pareto前解在某些目标上得到了改进，某些解在所有目标上都得到了增强，从而验证了所提优化过程的有效性。
