压气机转子多级动叶刮缸的频域特征

Frequency Domain Signatures Generated by the Rubbing of Multi-stage Rotor Blades with Casing in a Compressor

介绍压气机转子动叶径向刮缸所引起的振动的时域特征和频域特征,说明了某些频域现象产生的机理。

This paper describes the signatures in time and frequency domain caused by the radial rubbing of blades with casing in a compressor. Also explained is the mechanism governing the generation of certain frequency domain phenomena.
