Application Study on Resonance Demodulation Technique in Fault Diagnosis of Gear Box

Abstract:

Fault vibration signals of gear box are faint shock and are hardly extracted, which bring a big difficulty for diagnosis. This paper mainly introduces the basic principle of the resonance demodulation technique and its application study in the gear box’s fault diagnosis. The developed resonance demodulation technique can effectively extract the fault features from complex vibration signals through the resonance demodulation technique according to the vibration features of the gear box, and improve the equipments’ fault diagnosis precision.
