Gearbox damage identification using Ensemble Empirical Decomposition method

Abstract: In this article, we have conducted a comparative analysis of vibration signals from helicopter aircraft propulsion transmissions, registered on an industrial research stand. We compared acceleration vibrations in the case of gears without physical damage and gears with one tooth missing. Based on recorded signals, we determined the values of indicators based on the statistical properties of signals and compared them with each other. For a more exact comparison, the distribution of the tested signals to the emp… Show more

“…In the next stage, 49 damage/deterioration indices (DIs) are delineated based on computed coefficients and residuals of the AR model using statistical indices listed in Table A of the appendix. Besides, the majority of these indices are prevailing amongst researchers concerning damage identification purposes [42][43][44].…”
