Method and system for vibration signal processing

摘要

A method of vibration signal processing is disclosed. The method comprising the steps of: (a) obtaining electrical vibration signals having amplitudes and frequencies that represent mechanical vibrations of a machine; (b) converting the electrical vibration signals into digital vibration samples; (c) dividing the digital vibration samples into equal time intervals; (d) determining the average absolute amplitude of the digital vibration samples for each time interval; (e) generating a time waveform comprising the determined average amplitudes; and (f) processing the time waveform as if it were an independently-detected signal.
