摘　　要：舰船船型航行性能设计及优化是舰船总体设计的重要部分。针对以往迭代式的多方案船型设计及优选效率较低、难以获得全局最优解等不足,引入多学科设计优化方法,开展船型航行性能优化。以DTMB 5415标模船型阻力、耐波性和操纵性等综合优化为例,介绍船型多学科协同设计优化的一般过程,建立以典型性能指标为优化目标的数学模型,获得了综合航行性能明显改善的船型方案,验证了多学科设计优化在船型设计中的应用潜力。研究成果可为工程船型设计提供有益参考。Seqgoing performance design is of vital importance to naval surface combatants and it is a typicalMultidisciplinary Design Optimization（MDO） problem. The standard naval vessel hull model DTMB 5415 is taken in this paper to illustrate how to used MDO method to hull seagoing performance design. Resis-tance, seakeeping, and maneuverability are all considered in the optimization. Several seagoing perfor-mance indicators such as resistance, pitch amplitude, roll amplitude, and turning diameter are used as theoptimization targets, which leads to improved performance of the hull form, and the proposed MDO methodis thus validated.
