Abstract

There is a method (300), system (200), and device (220) for diagnosing an anomaly of a monitored component in a drive train (110), the method including obtaining original data based on samples of a vibration signal and a tachometer signal (310); generating a time synchronous average vibration signal (320); processing the time synchronous average vibration signal to produce a frequency-domain spectrum (330); determining the complex magnitudes of the frequency-domain spectrum (340); selecting a sub-synchronous band of the complex magnitudes of the frequency-domain spectrum to generate a sub-synchronous spectrum (350); and determining the mean of the sub-synchronous spectrum to generate a condition indicator (360).
