Determining the threshold Value for the Accurate Diaghosis of Bearings Hitch

introducing the determination of threshold value for the accurate diagnosis of bearings hitch,using the method of resonance demodulation and winding pack demodulation and also using hardware and software to proceed and analyze simultaneously.Through this way to go on the diagnosis of hitch.The main statement is the two thresholds determination of acceleration and coefficient and the judgment of hitch during the analyze of chart,so to get the better effect through this way,that is the combination of facility diagnose and accurate diagnose.
