A Sparse Modulation Signal Bispectrum Analysis Method for Rolling Element Bearing Diagnosis
Modulation signal bispectrum (MSB) analysis is an effective method to obtain the fault frequency for rolling bearing, but harmonics make fault frequency dense and even frequency aliasing. Carrier frequency of bearing is generally determined by its structure and inherent characteristics and changes w...
