多学科设计优化技术研究
首发时间:2013-05-28
摘要:多学科设计优化(Multidisciplinary Design Optimization,MDO)是一种通过充分探索和利用系统中的相互作用的协同机制来设计复杂系统工程和子系统的方法论。文中首先介绍了多学科优化的研究内容,重点探讨了多学科优化过程中的近似建模技术、灵敏度分析、分解技术及优化算法。针对MDO在各领域中的应用,主要对航空、汽车、工程机械、海洋领域进行了综述。最后讨论了多学科设计优化目前存在的问题和发展趋势。

The Research on Multidisciplinary Design Optimization
Abstract:In the design of complex engineering products, due to cross-coupling,subsystems often generate mutual restraint and coordination phenomenon,Multidisciplinary Design Optimization (MDO) ,as a new optimal design method,showed great superiority in handling the coupling between the disciplines and optimize efficiency .During recent years of research, MDO has been increasingly applied to aviation, engineering structures, automotive and other fields. This paper discusses the research content of MDO and its application of the various fields, and finally propose the the MDO's trends.
