Spectral Correlation Demodulation Analysis for Fault Diagnosis of Planetary Gearboxes

Spectral Correlation Demodulation Analysis for Fault Diagnosis of Planetary Gearboxes

Planetary gearbox vibrations exhibit complex amplitude modulation (AM) and frequency modulation (FM) characteristics. The spectral correlation (SC) can reveal the cyclostationarity of rotating machinery signals, but previous studies have modeled gearbox signals as impulse response signals rather tha...
