Abstract

This paper describes application of a non-contact vibration measurement and analysis method, which is based on discrete Fourier transform analysis of the vibration frequency of engine all-blades in a stage.By comparing the stage vibration frequency of all-blades in the stationary reference frame with the vibrations frequency in the rotating reference frame, the travelling wave structures of the engine rotor were analyzed in detail.According to the measurement of blades vibration in the compressor experimental, the vibration frequency is 1752.7 Hz in the stationary reference frame and 926.4 Hz in the rotating reference frame respectively at the speed of 12343 r/min, forming a four-nodal-diameter forward travelling wave.The frequency and speed margin were obtained by further connecting the travelling wave with the Campbell diagram of compressor rotor vibration.

Key words
