Research of Fault Diagnosis of Coalmine Motor Bearings Based on Scale Adaptive Lifting Wavelet Transform

Abstract:

For Rolling of the mine key equipment is damaged easily the problem which is machinery fault diagnosis,through the failure mechanism of the reload / variable load conditions and the weak fault signal characteristics of coal mine electrical equipment bearing are analyzed, a more refined analysis of the vibration signal and achieve coal mining equipment online monitoring and Intelligent Fault Diagnosis system is constructed directly by scale adaptive lifting wavelet transform
