Abstract

To solve the problem of adjacent order overlap for variable speed bearings, a novel method with the fixed-point independent component analysis (ICA) and peak detection is proposed. Firstly, the mixed vibration signal is whitened by through of the singular value decomposition. Then it introduces fixed-point ICA technique to separate the mixed vibration signal into different independent components. To improve the performance of separation, the adjacent orders are extracted by peak detection according to the energy distribution characteristics of separated signal. The effectiveness of proposed method is verified. Experimental results show that proposed method provides better performance on adjacent order separation for roller bearings.
