基于MDO理论,利用基于响应面的并行子空间优化算法,将水雷外形优化设计问题分解为一个系统级优化和阻力、流噪声两个学科级优化问题,建立了学科级精确计算模型和系统级近似模型,解决了学科间的耦合问题,实现了学科间的并行优化,实现了水雷外形低阻、低噪的综合优化设计,取得了较好的优化结果。 Based on the MDO theory and the response surface-based parallel subspace optimization algorithm, the optimization design problem of the mines is decomposed into two disciplinary-level optimization problems: system-level optimization, resistance and flow noise, and a disciplinary-level accurate calculation model and system-level approximation Model to solve the problem of interdisciplinary coupling, to achieve the parallel optimization between disciplines, and to achieve a comprehensive optimization design of low resistance and low noise of the mine shape, and achieve better optimization results.
