Extreme value statistics for vibration spectra outlier detection

Year: 2012

Type: conference-paper

Abstract: The issue of detecting abnormal vibrations from spectra is tackled in this article, when little is known about the mechanical behavior of the system, or the fault pattern. To do so, an original algorithm relying on the statistics of the maximum of log-periodograms is introduced. Receiver Operator Characteristic (ROC) curves are built and show good performance with bearing deterioration even when little wear is present.
