Rolling Bearing Fault Diagnosis Using Adaptive Variational Mode Extraction Based on Harmonic Coherence Factor Under Strong Noise

To address the challenge where early fault signals of rolling bearings are easily submerged by strong noise, and fault features are difficult to extract under harsh working conditions, this paper proposes an adaptive fault diagnosis method termed HCF-IAPO-VME. Firstly, a novel harmonic coherence factor (HCF) is constru...
