Fault diagnosis of rolling bearings based on improved enhanced envelope spectrum

Fault diagnosis of rolling bearings based on improved enhanced envelope spectrum

Aiming at the problem that traditional fast spectral correlation (Fast-SC) cannot effectively extract the fault feature of rolling bearings under strong background noise, we propose to select a band with abundant fault information on the spectral frequency axis by Spectral Gini Index (SGI) and integ...
