Abstract
A system for diagnosing performance degradation of a machine element includes an AE sensor that generates an AE waveform signal; a vibration sensor that generates an acceleration signal; a signal processing unit including an AE signal processing system that performs predetermined signal processing on the plurality of AE waveform signals, a vibration signal processing system that performs predetermined signal processing on the acceleration signal, and a switching parameter generating section that generates a predetermined numeric parameter to switch a measuring mode from the AE method to the vibration method; and controlling unit that selects a result of the processing in performed by the AE signal processing system at the initial stage and selects, after the numeric parameter successively turns from increasing to decreasing, a result of the processing by the vibration signal processing system.
