英文摘要：

To complete coupling analysis in complex product design,definition of product design coupling and its description methods were introduced.The coupling research in product design was categorized into direct coupling analysis and coupling propagation（indirect coupling） analysis.According to different matrixing coupling representation method,the direct coupling analysis method which was commonly used at present and its application in product design were elaborated to summarize common essence of these methodologies.General process and difficulties in the coupling propagation analysis were introduced.Change propagation judgment method based on graph theory and change propagation analysis method based on Design Structure Matrix（DSM） were discussed.The comparison of the studies on direct coupling and coupling propagation and the existing problems were also discussed.The direction and problem in further study of product design coupling analysis,which deserved were presented.
