基于实例推理的夹具设计(中文3500字,英文2400字)
  摘要：基于案例的设计（CBD）方法，夹具相似性体现在两个方面:功能和结构信息。然后，计算机辅助夹具设计系统是建立在基于案例的推理（CBR），并对工件和夹具结构的主要特征属性作为案例索引代码用于检索类似的情况，并且结构和案例库的层次关系建立商店，同时，算法在检索相似案例知识的引导，案例策略适应在离子和案例库中案例验证如果猫离子数是用来区分相似的案例，该系统在某工程中的应用提高了设计效率，取得了良好的效果。

Of case based reasoning in fixture design
Abstract: Based on the case based designing (CBD) methodology, the fixture similarity is in two respects: the function and the structure information. Then, the computer aided fixture design system is created on case based reasoning (CBR),in which the attributes of the main features of workpiece and structure of fixture as case index code are designed for the retrieve of the similar cases, and the structure and hierarchical relation of case library are set up for store. Meanwhile, the algorithm based on the knowledge guided in the retrieve of the similar cases, the strategy of case adapt at ion and case storage in which the case ident if cat ion number is used to distinguish from similar cases are presented. The application of the system in some projects improves the design efficiency and gets a good result .
