Multi-speed Multi-load Bearing Diagnostics Using Extended Phase Space Topology

Abstract

This paper presents the application of Extended Phase Space Topology (EPST) and conventional statistical time domain features in the diagnostics of various bearing faults in rotating machinery systems. Bearings with various health statuses operating under multiple motor loads and speeds are analyzed. The results indicate remarkable performance in detecting anomalous behavior and in identifying faults with virtually perfect accuracy, recall and precision.
