Defect Detection for Wheel-Bearings with Time-Spectral Kurtosis and Entropy
Wheel-bearings easily acquire defects due to their high-speed operating conditions and constant metal-metal contact, so defect detection is of great importance for railroad safety. The conventional spectral kurtosis (SK) technique provides an optimal bandwidth for envelope demodulation. However, thi...
