2022, Engineering Failure AnalysisCitation Excerpt :They extended their research and offered various statistical moments to monitor bearing faults [5]. Their research shows the effectiveness of skewness compared to kurtosis for initially corrected signals. [6] extracted the well-known statistical attributes, namely, kurtosis, skewness, and crest factor, along with attributes acquired from beta distribution to recognize the existence of a fault in the bearing.

2022, Materials Today: ProceedingsCitation Excerpt :The same methodology was also tested successfully to diagnose the impacts generated on a signal collected from a spalled outer race bearing of a gearbox. Heng et al. [10] carried out a statistical analysis of sound pressure and vibration signal to detect defective rolling element bearing. Wavelet Transform (WT) was preliminarily developed by Malat [11], where it is seen that WT is superior to FFT for non-stationary signals.
