Fault Diagnosis System Research of Large-scale Linear Vibrating Screen

Abstract

The paper takes side panel cracks of large-scale Linear vibrating screen as research object and designs the hardware and upper computer diagnosis interface of fault diagnosis system. The side panel vibration signals have been de-noised and the wavelet packet energy feature has been extracted in Matlab with wavelet analysis theory. Meanwhile, the fault characteristic is sent to genetic neural network for identification. The practical manufacturing application shows that this kind of side panel crack fault diagnosis system of large-scale vibrating screen based on wavelet analysis has high fault recognition ability, classification precision and speed.
