Application of Cyclic Correlation Analysis to Gear Damage Detection

摘要：

The cyclic autocorrelation function is used with regard to the cyclostationarity of gear vibrations in order to extract the modulation features of gearbox vibration signals,and to detect localized gear damage.The properties of the amplitude and frequency modulated signals in the cyclic frequency domain are summarized in order to investigate the differences between the modulation features of normal and faulty gearbox vibration signals.Gear tooth spalling is detected by the presence of many sidebands in a zero-lag time-slice of the cyclic autocorrelation function,thereby indicating an increase in the degree of modulation effect.The damage source is located by the spacing of the sidebands.
