Analyzing For Couping Feature And Optimization For The Complex Product Configuration Model And Its Application In High-End CNC Industry

With the rapid development of science and technology, modern enterprises are facing increasingly fierce competition. So accurately and quickly responding to customer demand, shortening product design cycles and improving product design efficiency are important factors to ensure enterprises remain successful in today's highly competitive market environment. In the dissertation, quantitativing for couping feature of the complex product configuration model and Optimization for complex product configuration model based on coupling intensity DSM. Based on the technologies presented in the paper. The system of modular intelligent configuration design is developed which is applied in the high-ended CNC design process, and achieved good results.The dissertation is organized as follows:In the first chapter, the dissertation introduces the development of the theory, status of research and practical application of design technology of modular configuration. elaborateed the background, content and significance of the paper.In the second chapter, the dissertation investigates the realization and submission of quantitativing for couping feature of the complex product configuration model. Firstly, the product configuration structural element (PCSB)is defined, the Coupling analysis and quantitative study for configuration model can be achieved according to the Parent-child and Constraint relationship between PCSB. On this basis, the constraint relationship between PCSB is divided into internal constraints and external constraints. The the integrated coupling strength is Calculated based on internal coupled constraints and different characteristics of external constraints, then the quantitative study for configuration model can be achieved. At last, as the case of HMS125, the quantitativing for couping feature of the configuration model is elaborated in detail.In the third chapter, the dissertation investigates the technology of Optimization for complex product configuration model based on coupling intensity DSM. Though the research of the traditional design structure matrix, the coupling intensity DSM which can reflect the strength bwteen the PCSB is presented. On this basis, Coupling Intensity Design Structure Matrix is obtained by the mapping mechanism from configuration model to DSM, the ploymeric set of PCSB can be formed by the decomposition of CIDSM and determine of the polymeric degree index function. After that, tear the ploymeric set by the method of decoupling algorithm based on Pure Supply Degree, restructuring PCSB sequences, optimizing the product configuration model. This technology has been applied to practical use in the configuration design of CNC machine tools with the efficiency and accuracy of configuration design being improved remarkably.In the fourth chapter, The system of modular intelligent configuration design is developed based on the technology discussed above. What's more, this system has been applied in high-ended CNC configuration design process. It tests and verifies that the theory and methods mentioned above are feasibility.In the fifth chapter, All achievements of the paper are summarized in order to put forward the further research.
