Quantitative fault analysis of roller bearings based on a novel matching pursuit method with a new step-impulse dictionary
We proposed a novel matching pursuit method forquantitative analysis of roller bearings. A new step-impulse dictionary is constructed for atom selecting. The method presents good results in the application of both simulated signals and experimental signals. An atomic selection mechanism is proposed to improve the measure accuracy of the bearing spall-like fault size.
