In order to identify sources from rotor-bearing system,analyze the mechanism of nonlinear dynamics for fault rotor,a method for sources recognition based on wavelet-independent component analysis(ICA) was proposed.By combining the advantages of wavelet packet and ICA,every independent sources embedded into multi-channel observation by sensors were separated.Experimental results show that this new approach is satisfactory and it is a new method for the recognition of nonlinear vibration response of rotor-bearing system.
