Blind Source Separation of Rotating Machine Faults Based on FastICA
Zhengping Liu · Coal Mine Machinery · 2008
A new FastICA algorithm based on Newton iteration method is proposed.Based on the method developed,the numerical simulation of vibration signal blind source separation was performed.And this blind source separation method was applied to multi-sensor signals of a real rotor faults.The computer simulation and experimental verification show that the algorithm can well restore source signals from their mixtures.This method can be seen as a pre-processing step that improves the diagnosis for rotating machine.
