TLDR
This communication describes a fast algorithm for computing the kurtogram over a grid that finely samples the ( f, Δ f ) plane and the efficiency of the algorithm is illustrated on several industrial cases concerned with the detection of incipient transient faults.About:

Rolling element bearing diagnostics—A tutorial
Robert B. Randall,Jérôme Antoni +1 more
TL;DR: This tutorial is intended to guide the reader in the diagnostic analysis of acceleration signals from rolling element bearings, in particular in the presence of strong masking signals from other machine components such as gears.

Rolling element bearing diagnostics using the Case Western Reserve University data: A benchmark study
Wade A. Smith,Robert B. Randall +1 more
TL;DR: Though intended primarily as a benchmark to aid in testing new diagnostic algorithms, it is also hoped that much of the discussion will have broader applicability to other bearing diagnostics cases.
Journal ArticleDOI
The enhancement of fault detection and diagnosis in rolling element bearings using minimum entropy deconvolution combined with spectral kurtosis
TL;DR: In this article, the minimum entropy deconvolution (MED) technique was used to enhance the surveillance capability of the spectral kurtosis (SK) by using a spalled inner race bearing.
Journal ArticleDOI
A novel method for the optimal band selection for vibration signal demodulation and comparison with the Kurtogram
Tomasz Barszcz,Adam JabŁoński +1 more
TL;DR: In this paper, the authors proposed a method based on the kurtosis of the envelope spectrum amplitudes of the demodulated signal, rather than on the filter time signal, to detect transients with smaller signal-to-noise ratio comparing to the spectral kurtogram.
Journal ArticleDOI
The infogram: Entropic evidence of the signature of repetitive transients
TL;DR: It is demonstrated that the joint consideration of the infograms significantly extends the domain of applicability of the kurtogram, in particular to situations corrupted with impulsive noise or when the relaxation time of the transients is low as compared to their rate of repetition.

The spectral kurtosis: application to the vibratory surveillance and diagnostics of rotating machines
Jérôme Antoni,Robert B. Randall +1 more
TL;DR: In this article, the spectral kurtosis (SK) was used to detect and characterize nonstationary signals in the presence of strong masking noise and to detect incipient faults in rotating machines.

Application of the wavelet transform in machine condition monitoring and fault diagnostics: a review with bibliography
Zhike Peng,Fulei Chu +1 more
TL;DR: The application of the wavelet transform for machine fault diagnostics has been developed for last 10 years at a very rapid rate as mentioned in this paper, and a review on all of the literature is certainly not possible.

The spectral kurtosis: a useful tool for characterising non-stationary signals
TL;DR: A formalisation of the spectral kurtosis by means of the Wold–Cramer decomposition of “conditionally non-stationary” processes is proposed, which engenders many useful properties enjoyed by the SK.

Jing Lin,Ming J. Zuo +1 more
TL;DR: In this article, an adaptive wavelet filter based on Morlet wavelet is introduced to detect early fatigue tooth crack in a gearbox with early fatigue teeth crack using the kurtosis maximization principle.

Detection of non-Gaussian signals by frequency domain Kurtosis estimation
TL;DR: This work has considered sinusoidal and narrowband Gaussian signals which, when propagated through fading or multipath environments, are received as non-Gaussian in terms of a frequency domain Kurtosis estimate.
