The Present Status and Development of Acoustic Emission Technique in Diagnosis of Rotating Machinery Faults

摘要：

Abstract -In this paper, AE source, propagation characteristic, AE parameters, the noise and the advantages of acoustic emission method for the diagnosis are expounded. The last ten years research conclusions of many important experiments and the signal processing methods which were used for the diagnosis of rolling equipment faults are summarized. The results come from UK, USA and China, etc. The signal processing methods consist of Wavelet Transform, Wavelet Packets and Neural Network, etc. The contradictions of the results are discussed. These summaries are helpfui to the new researchers. Through analyzing these results, we could conclude that although there is a lot of work to do, the diagnosis of early rolling equipment faults will be resolved by Acoustic Emission technology not vibration analysis.
