多学科优化设计技术在现代鱼雷设计中的应用展望

介绍了国内外多学科优化设计技术的现状与发展，基于该技术在国内起步较晚、在鱼雷领域的应用还是空白的现状，展望了多学科优化设计技术在现代鱼雷技术中的应用，认为应从4个方面开展工作：建立适合鱼雷使用的系统优化模型；确定优化算法；研究优化设计流程；建立鱼雷总体多学科优化设计平台，从而实现全雷各系统各学科的协同设计，提高鱼雷总体设计水平。同时介绍了几种优化算法，如单级优化算法、并行子空间优化算法和协作优化算法，以及几种优化设计平台，如美国Engineous Software公司开发的iSIGHT软件、Sandia国家实验室开发的DAKOTA软件、Vanderplaats开发的VisualDOC软件、Phoenix Integration公司开发的ModelCenter软件等的技术特点。

Prospect of Application of Multidisciplinary Design and Optimization to the Design of Modern Torpedoes

This paper introduces the current situation and development of multidisciplinary design and optimization(MDO)technology.It is pointed out that this technology is applicable to modern torpedo design by building up system optimization model suitable for torpedo,determining the optimization algorithm,optimizing design process,and establishing the multidisciplinary concurrent platform for torpedo overall design and optimization.Therefore,coordinated torpedo design among different systems and disciplines can be implemented to raise the overall design level.Moreover,this paper presents several optimization algorithms,such as single-stage optimization,concurrent subspace optimization and collaborative optimization.It also introduces some optimization design platforms including iSIGHT software,DAKOTA software,VisualDOC software,and ModelCenter software developed respectively by Engineous Software Company,Sandia National Laboratory,Vanderplaats Research & Development,Inc.,and Phoenix Integration Company.
