Fault Diagnosis of Rolling Bearings Based on Improved Kurtogram in Varying Speed Conditions

Fault Diagnosis of Rolling Bearings Based on Improved Kurtogram in Varying Speed Conditions

Envelope analysis is a widely used method in fault diagnoses of rolling bearings. An optimal narrowband chosen for the envelope demodulation is critical to obtain high detection accuracy. To select the narrowband, the fast kurtogram (FK), which computes the kurtosis of a set of filtered signals, is...
