Research On Computer Aided Product Modular Design And Its Application In Damper Design

The aim of modular design is that with minimum types and quantities of modules to compose as much as possible types of products, that is to say, with minimum cost to meet the different market needs. With the development of individuation and mass customization, modular design attracts more and more people's attention because of its advantages, such as quick response to market changes, shorter cycle of product design, lower cost of product, and so on. With the rapid development of auto industry, the demands of dampers are increased rapidly. There are many kinds and series of dampers in the company, through making use of modular design, the company can raise the speed of product design, reduce product cost. To meet the requirements of the project - 'Key-Technologies-Tackle in Vehicle MR Damper for semi-active control' and the project of ZhengYu Company, the method of computer aided modular design is researched based on the method of modular design, and it is applied in the damper design. This thesis consists five chapters:In chapter one, the status of present research and the key technology of modular design and parametric design are introduced, the problems of that are analyzed, then the purpose and content of this study are educed;In chapter two, the methods of modular partition are analyzed and the method of multi-target modular partition is researched based on analyzing and comparing the methods of modular partition. Fuzzy clustering algorithm is improved, and then a module of computer aided modular partition is developed and applied to the damper;In chapter three, the method of part reengineering based on similarity is advanced. The part similarity based on feature is researched, and then a module of computer aided part reengineering is developed and applied to the damp. The method model drove by data tables to manage of series parts is employed, and then family tree of Pro/E that found two-level data table drove model is applied to piston pole;In chapter four, the mode of man-computer alternate and rule combination of modular configuration is chosen, the composition of module information and the rule of module configuration are researched, and it's applied in damper;In chapter five, a method of modular design and parametric design which based on data-base is advanced. A modular design system which can realize the function of modular configuration and parametric design is developed based on Pro/E system.The last chapter, the thesis is summarized, and the further work is expected.
