声发射检验技术进展

The Progress of Acoustic Emission Testing Technique

本文简要介绍了声发射技术的发展史 ,并从声发射技术的原理、波形分析法、参数分析法、声源定位技术和声发射仪器几个方面进行了综述 ,主要讨论了最新的波形分析技术和检测仪器的构成。

This paper introduces the history and principle of acoustic emission technique(AET).The technical progress of wave analysis,resonant sensor parameter,source location and AE equipment is reviewed.At last,this paper indicates that the direction of Ae testing is pattern recognition and artificaial neural network pattern recognition alalysis of AE signals.
