Correlation Spectrum of Frequency Difference and Sidebands Identification of Defective Gear
Luo Jun Tong Dechun
Based on the research of sidebands of gear vibration,a new con-cept,“Correlation Spectrum of Frequency Difference”(CSFD)is proposedto describe the correlativities of the sidebands,whose characteristics andnatures are also disenssed.In order to demonstrate the value and practicab-ility of this concept,CSFD is used to analyse vibration data obtained on agearbox case.The result has revealed the effect of demodulation of the si-debands.CSFD is proved to be a kind of useful,convenient and effectivetool in recofnizing features of sideband signals.This paper points that CSFDhas a great significance both in theory and in practice in the area of faultdiagnosis and signal processing.
