摘　　要：提出了一种新的航空发动机转子系统模型化及分析方法,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。The future of the rotor dynamics and the model of rotor system is directed toward the implementation of Artificial Intcligence technique to quickly capture and use knowledge as a important re-source. This paper presents a new modeling method which has combined an efficient model synthesis algorithm.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 also 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 故障诊断 模态综合 失效模式
