Research And Application Of Automobile Key Components Design System Based On CBR

Nowadays,the cross-border automobile components tycoon companies have dominated the market of key automobile components. If Chinese automobile components enterprises wanted to enter the international automobile components' buying system,they would gradually form the systematic developing capacity in the key automobile components field and advanced developing and creating capacity of products in general automobile components field,in order to meet the needs from the internal and external markets.The case knowledge on product design,as an important part of product design knowledge of the enterprises,is the treasure of enterprises. The efficient reusing of the case knowledge can urge enterprises to make full use of the present designing resources and improve the quality and efficiency of product design. This paper has focused on the case representation,case retrieval and modification of the product case design,and it has done a deep research on it .First, this paper has researched on the case-based product design method, expressing the case knowledge with the combination of framework representation and object-oriented knowledge representation .Then, it's done a deeper research on the case retrieval and algorithm as well as the similarity algorithm based on the nearest-neighbor method. Finally, it's combined CBD method and technology of Secondary Development on UG to develop a CBD system on designing automobile key components. Facts have proved that CBD theory meets the piratical needs of the present Chinese automobile components enterprises, and it's made a great contribution to increasing the developing capacity on products and shortening the developing time of new products of enterprises.
