Blind Source Separation Applied to Rotating Machine Monitoring and Fault Detection
Guillaume Gellé, Maxime Colas · Noise & Vibration Worldwide · 2001
This article presents a processing technique called “Blind Source Separation” initially developed for telecommunication applications and now applied to vibration monitoring of mechanical systems. Experimental results illustrate the potential of blind source separation as a pre-treatment to free the signal from its environment (denoising), so as to improve fault detection and diagnosis. An example of bearing faults detection on an experimental test bench is presented.
