摘要:

根据航空发动机叶片锻件的特点,提出了基于相似理论和层次分析(analytic hierarchy process,AHP)法的锻件模型实例检索策略。首先,根据锻件的形状特点提出了定性检索空间和定量检索空间,并根据这两个空间包含的信息提出了检索求解过程;其次,根据相似理论中的相关计算公式和AHP法,提出了检索求解所需的基本公式和权重值计算方法;最后,以某型号航空发动机低压转子二级叶片为例,给出了验证实例。

According to the characteristics of the aero-engine blade roughcast, a retrieve strategy for roughcast model was proposed based on the similarity theory and AHP method. Firstly, the qualitative retrieve space and quantitative retrieve space were proposed, and based on the two spaces a retrieve process was proposed. Secondly, based on the similarity theory and AHP method two basic formulas and a series of weights were evolved. Finally, a case was given to validate the retrieve strategy. 

Key words: similarity, weight, analytic hierarchy process(AHP), blade roughcast, retrieve
