摘要
以航空发动机附件装置中的管路系统为研究对象,在总结国内外研究成果的基础上,对比分析了管路系统耦合振动机制及故障诊断等内容,指出了管路系统的非线性振动特征分析、振动故障机制与故障模式研究和管路系统的振动故障诊断是航空发动机管路系统振动消减和排故的研究方向。
The pipe system of aero-engine accessory unit was studied. The-recent researches about the fault diagnosis and cou- pled vibration mechanism of the pipe system at home and abroad were summarized, and the related contents were analyzed. It＇ s pointed out that the vibration characteristic analysis, the vibration fault mechanism and fault mode, and the diagnosis of the pipe sys- tem vibration fault are the research directions of the vibration cut and troubleshooting of the pipe system of aero-engine.
