RESEARCH ON THE COUPLED FACTORS IN MDO FOR COMPLEX PRODUCTS

Abstract

Abstract: In the complex product optimization, it is difficult to use any approaches of multidisciplinary design optimization (MDO) because of the existence of coupled factors. In order to help solve this problem, the components and affection of coupling factors are discussed. The coupled factors are divided into three classes. According to the global sensitivity equations (GSE), the properties of couplings between sub-systems are analyzed. The criterion that can determine a redundant coupled factor is gotten. And some strategies for handling the couplings are presented on the basis of coupled properties. An example is given to show the results achieved.

Key words: Collaborative optimization, Coupled system, GSE, Solving strategy
