Research Of Rubber Sealing Products Knowledge Management System

In order to provide products of best quality for market with the fastestspeed and lowest cost, product design gradually shows the trend of highspeed,modularization and knowledge coverage.It is required to know thedetailed processes of product design and obtain useful knowledge ofproduct design in the possible shortest time. It can realize the knowledgesharing and reuse.This paper puts forward the framework of knowledgemanagement by applying the full lifecycle of products and the thought ofdesign reuse.It discusses the seal products knowledge management fromthe points of view of the knowledge model,knowledge base modulefamily and mold of intelligent design,thereby the purpose of giving the right knowledge to the right person at the right time is achieved.It canspeed up product design,accumulate design knowledge,and encouragethe development of modular design.First,the full lifecycle oriented information model of seal productsmodule family and the character model were established on the basis ofthe system needs analysis. The SML technology was studied, and on thatbasis the full lifecycle oriented object attribute information model andthe parts of the product information model were established using SMLtechnology.Second,on the basis of analyzing the design knowledge of partfamily,module family and product family of seal products, thecorresponding knowledge main model was established respectively.Theseal products knowledge base was established by using object orientedmethod,and it expounds the organization form of knowledge andexamples and rules in the knowledge database storage is how toachieve.Each function module of the knowledge base management was discussed in this paper.Standard parts library,general partslibrary,document library and compound recipe library of the sealproducts were established in the system.Then,on the basis of analyzing the structure of rubber seal mold,thestructure of the mold design system and the rules of mold design wereput forward.According to the structure characteristics of rubber sealmold,the parameters of the parts mainly divided into mainparameters,additional parameters,the independent parameters,and wegives the parts of the constraint relation between the parameters.Themold assembly design and structural parameters of control were realizedby using the rules and knowledge base,and the intelligence of molddesign were realized as well.Finally,with the above content as the foundation,the rubber sealproducts knowledge management system were designed and realized.
