Blind spectrum-guided adaptive cyclic refinement network for bearing fault diagnosis under complex interference

The extraction of weak bearing fault features remains a formidable challenge in the field of mechanical health monitoring, particularly under strong background noise and non-periodic random shocks. Although blind deconvolution methods can effectively eliminate transmission path effects, their reliability is severely re...

Robust bearing fault diagnosis under strong impulsive interference via envelope spectrum harmonic-to-noise ratio guided sparse filtering

Early fault signatures of rolling bearings are typically very weak and are often contaminated by strong background noise and random impulsive interference. Traditional kurtosis-based feature extraction methods are highly sensitive to non-fault-related large random impacts, which may result in incorrect frequency-band s...
