Kurtosis is a statistical parameter used to characterize a signal. In essence it provides a measure of the “peakedness” of a random signal. Signals that have a higher kurtosis value have more peaks that are greater than three-sigma; that is, peaks that are greater than three times the RMS value of the signal.
OVERVIEW. This guide is designed to introduce machinery maintenance workers to condition monitoring analysis methods used for detecting and analyzing machine component failures. This document was created by field experienced SKF application engineers using measurements obtained with SKF Condition Monitoring equipment.

19 wrz 2016 · The results show that the approach is viable and that the synthesized random waveforms can be easily tailored to simulate a variety of real-world acoustic/vibration signals, e.g., high...
10 mar 2023 · Kurtosis and Skewness. The metrics of Kurtosis and Skewness (also translated as distortion or asymmetry) are two important statistical parameters. These parameters are used to qualitatively describe the shape of a vibration signal.
KurtosionTM , the patent-pending technique developed by Vibration Research Corporation, is a kurtosis control method that can effectively bring large peak accelerations into the random vibration test.
