摘要
基于多学科设计优化(MDO)理论,结合鱼雷外形各学科优化设计方法,将鱼雷外形优化设计问题分解为一个系统级优化问题和阻力学科、自噪声学科和压力分布学科3个学科级优化问题,建立了鱼雷外形多学科设计优化模型,解决了各学科之间、学科与系统之间的耦合问题,实现了并行计算,并结合实际算例,验证了该方法的有效性。
Based on the multidisciplinary design optimization （MDO） theory and the methods of various disciplines for torpedo shape optimization design, the torpedo shape design optimization problem is decomposed to one system optimization problem and three discipline optimization problems, including drag discipline, self-noise discipline and pressure distribution discipline. A tor- pedo shape multidisciplinary design optimization model is established, the coupling problems between system and each discipline and among various disciplines are resolved, and parallel computation is realized. Computation of a practical example verifies the effectiveness of the proposed method.
