Based on Blind Source Separation of Gearbox Fault Diagnosis
Yang Xiao-xia · Coal Mine Machinery · 2012
Mainly researched blind source separation algorithm based on maximum signal-to-noise ratio,in view of four groups of signal mixed signal isolation simulation experiment,get a good separation effect,and is applied to gear box vibration signal of separation.For a few sets of vibration signal analysis results show that algorithm has a strong separation ability for mixed signals.This is provided a powerful signal pretreatment method for fault diagnosis of mechanical equipment.
