民用活塞式航空发动机试飞中振动测定研究

Research on Vibration Measurement of Civil Piston Aviation Engine in Flight Test

通过查阅大量资料并结合型号试飞经验,对民用活塞式航空发动机的振动测定进行了系统的阐述,包括活塞式发动机振动测定研究的现实环境、研究背景和意义、振动机理与特性、振动信号测量与分析等内容,最后推荐了一些在试飞中可以参考的标准文件。

The research on vibration measurement of civil piston aviation engine is expounded systematically in this paper by looking for a great deal of related literatures and combining the models practical flight test experiences, including the realistic research environment, background and significance, vibration mechanism and characteristics, vibration signal measurement and analysis, finally, some suggesting standard and specification to the flight tests are recommended.
