摘　　要：提出了一种新的航空发动机转子系统模型化及分析法，将计算机辅助模型化、子结构模态综合法与复杂结构设计的专家系统技术相结合，利用知识库存储的知识，进行转子系统模型建立、模型的分析诊断和转子系统的再设计。A new modeling method is presented,which has combined an efficient modal synthesis algorithm.It is different from the conventional modal synthesis algorithm that this method is based on the knowledge of experience and data.The goal of this algorithm is to assist the user in closing the loop of modeling,diagnostics and redesign.An example of an aircraft engine model will aslo be used to illustrate the advantage and limitations of our method,as compared with the conventional manual method.

关 键 词：转子动力学 专家系统 失效分析 模态综合法
