Describes the mechanism and characteristics of the rotor system failures'oil whirl an d oil whip.The harmonic wavelet transform is used to process rotor speed signal up for failure analysis,extracting fault information to identify the whirl and oil whip.Simulates the rotor oil whirl and oil whip by the rotor test bed.The signal processing system based on harmonic wavelet filtering is developed with the Labview platform.It shows that the conversion result of harmonic wavelet is better than FIR digita...
