摘　　要：概念设计方案实例的知识表达关键是将CBR应用于产品概念设计。将行为信息引入公理化设计中 ,建立了扩展“之”字映射 ;在此基础上 ,构造了概念设计方案实例的知识表示模型———域结构模板 ;给出了基于域结构模板的多方案生成过程。以高速链式平缝机为例对所述模型和方法进行有效性验证。The knowledge expression of scheme case in conceptual design is the key for applying CBR to product's conceptual design.The extended zigzagging mapping is established by introducing behaviour information into axiomatic design. The domain structure template,which is a model for knowledge expression of scheme case in conceptual design,is constructed on this basis. The process of multiple schemes generation based on domain structure template is proposed. Taking the chained high speed plain sewing machine as an example,a verfication of effectiveness was conducted on the stated model and method.
