Feature Extraction of Weak Fault for Rolling Bearing based on Spectral Kurtosis and MOMEDA

Feature Extraction of Weak Fault for Rolling Bearing based on Spectral Kurtosis and MOMEDA

Aiming at the problem that the early periodic transient impulse of rolling bearings is not obvious and the spectral kurtosis is poorly analyzed under low signal-to-noise ratio， a method of extracting the weak fault features of rolling bearing based on the combination of multipoint optimal minimum en...
