Fault Diagnosis Based on Higher-Order Cumulant Spectrum for Bearings

摘要：

Vibration signals of bearings in different states are contrasted and analyzed. The Higher-order cumulant spectrum (bispectrum) of the bearings vibration signals has been extracted. The analysis results show that, compared with power spectrum, the characteristic extracting from the Higher-order Cumulant spectrum is more sensitive to the fault characteristic, and easy to realize the digital characteristic extracting in the intelligent diagnosis. It can identify the fault of bearings effectively.
