面向飞机结构划分的CBR技术

飞机装配工艺设计需要大量借鉴以往机型的设计方案.对设计知识的重用是提高飞机装配工艺设计效率的有效保障.研究装配单元划分知识表示与重用技术,提出一种基于实例的航空产品装配单元划分设计方法,通过对装配单元划分知识的组织构造装配单元划分实例模型,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要求的最佳匹配实例.以某机型机翼梁为例进行算法验证.

Research on CBR technology orientating structural participation of airplanes

A great lot of designing schemes of the former typed plane needs to be used for reference for the technological design of airplane assembly.The reuse of designing knowledge is an effective guarantee for enhancing technological designing efficiency of airplane assembly.This paper studied the knowledge representation of partition of assembling units and the reuse techniques,and put forward a kind of designing method for the partition of assembly unit of aviation products based on certain living example.The case model of assembly unit partition was constructed by means of the constitution partition knowledge of assembly unit.The optimal matching example that tally with the designing requirements was obtained by adopting the case searching algorithm based on extent of similarity and by means of the search of living example.Verification of the algorithm was carried out by taking the wing girder of certain typed plane as an example.
