多学科设计优化技术研究

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.
