Abstract

A vibration fault occurred on a fan booster stage: fundamental frequency vibration increased suddenly and reduced soon, but it exceeded limit value yet; serious damages were found in the checking after stopped running. In order to find out the reasons for this fault, analysis on rotating speed was conducted, and a period of vibration signal was locked for fault analysis. Wavelet analysis and fast fourier transform(FFT) segmented contrast analysis were finished to infer the abnormal vibration frequency. A fault mechanism was presumed based on comprehensive information including stator case modal experiment, rotor drum modal analysis and orbit analysis, which was the resonance of the 3-nodal-diameter backward travelling wave of rotor drum due to friction between stator and rotor. Rectification measures were made according to fault mechanism, which were proven being effective through experiment. The characteristics of vibration fault and the method of fault diagnosis in this vibration fault event were summarized, which have an important reference value on similar fault diagnosis.
