摘要:
某型航空发动机使用多年来,积累了大量的故障诊断案例,并且发动机维修专家也积累了丰富的排故经验,这些经验较容易表示成案例的形式。本文利用案例推理技术对某型航空发动机智能故障诊断进行研究,讨论了发动机故障案例表示与组织、故障案例检索及学习等关键技术,并用发动机故障实例进行了应用验证,结果表明:该诊断方法是合理有效的,具有良好的故障诊断性能。

Abstract: As the using of one given aero-engine for several years, a lot of fault cases are obtained, and the rich experiences of diagnosis are got by the experts, which could be expressed by fault case. The paper researches the application of case-based reasoning (CBR) technology to aero-engine intelligent fault diagnosis. The crucial technologies such as engine fault representation, organization, retrieval and study are discussed. The result of application shows that the fault diagnosis based on CBR is efficient and has good performance of fault diagnosis.
