为充分利用已有设计知识实现钳臂的快速设计,提出了一种将知识重用与参数化设计相结合的方法。分析了钳臂的结构和设计知识特点,并对知识进行了分类、表示。利用知识工程和参数化设计将事实性、过程性知识应用到标准模型中,用实例表示网格划分信息知识。在知识重用方面,采用基于实例的推理技术,并结合钳臂实例的属性相似度及历史设计的指导因子,检索与当前设计要求最匹配的实例。最后,通过实例验证了该方法的可行性与有效性。
為充分利用已有設計知識實現鉗臂的快速設計,提齣瞭一種將知識重用與參數化設計相結閤的方法。分析瞭鉗臂的結構和設計知識特點,併對知識進行瞭分類、錶示。利用知識工程和參數化設計將事實性、過程性知識應用到標準模型中,用實例錶示網格劃分信息知識。在知識重用方麵,採用基于實例的推理技術,併結閤鉗臂實例的屬性相似度及歷史設計的指導因子,檢索與噹前設計要求最匹配的實例。最後,通過實例驗證瞭該方法的可行性與有效性。

To make full use of existing knowledges on clamp arm design,a method combined knowledge reuse and parametric design was put forward to realize the rapid design.The characteristics of clamp arms structure and design knowledge were analyzed,and the knowledge was classified and re-presented.The factual and procedural knowledges were applied to the standard models utilizing the knowledge engineering and parametric design,and the mesh information was represented through the instances.Through the CBR,the most matching instances were searched out according to the attribute similarity between the new instance and original instances,as well as the guidance factor of history de-sign.Finally,a case study was demonstrated to show the feasibility and validity of the proposed method.
