Abstract:

This paper studied the partitioning assembly cells for aircraft using CBR. The case to organize the knowledge of the partitioning assembly cells was constructed, including the geometrical and physical information, and the similarity-based retrieving was adopted in case retrieval algorithm. The best matching case for the design requirements on the case-based is obtained using the similarity-based retrieving. The algorithm was validated in a certain kind of girder of the aircraft wing assembly.

Key words: case-based reasoning(CBR), assembly cell partition;query case;similarity-based retrieving

摘要：

研究了面向飞机装配单元划分的基于实例的推理技术，通过对零部件几何和非几何特征的组织,构造实例的表示模型，采用基于相似度的实例检索算法，通过实例的检索获得符合设计制造要求的最佳匹配实例,并以某机型机翼梁为例进行了验证。
