Design And Realization On The Basis Of Mechanical Transmission Product's Cases

Product design's case knowledge, as a part of product design's knowledge, is valuable treasure in the enterprise. Its effective reuse can promote enterprise to make the best of existed design resource to increase design's quality and efficiency. This paper studies product design's technique home, which involves case representation, case search, case modification and case maintenance.At first the dissertation introduces the essence of product design, knowledge-based intelligent design, the idea and significance of design reuse, and researches Case-based Reasoning (CBR) method, which is the important supporting method of design reuse. Secondly the dissertation adopts object-oriented method to express the instance knowledge of product design. Thirdly we provide similarity degree's detailed calculating methods of the main product character. At the same time effective methods about case modification and conservation are put forward. Fourthly the dissertation points out the arithmetic to resolve the problem of redundant cases, obsolete cases, hotspot cases and cases addition. The methods are used to maintain the case-base to preserve the solution's quality and efficiency of the system. Simultaneously this dissertation offers an applied resolvent about case collision. Finally this paper employs kernel technique on retarder design.
