Differentiated time-frequency envelope kurtosis-gram guided adaptive variational multi-harmonic mode extraction for fault diagnosis of offshore wind turbine slewing bearings

Early fault characteristics of offshore wind turbine slewing bearings are weak and easily masked by noise, making accurate extraction difficult. To address this problem, a differentiated Time-Frequency Envelope Kurtosis-gram (TFEKgram) guided Adaptive Variational Multi-Harmonic M...
