Analysis of Acoustic Emission Signal Features Based on Wavelet Transform

摘要

摘要: 对声发射信号进行分析与处理是目前获取声发射源信息的唯一有效途径，也是声发射技术发展的难点和瓶颈。针对声发射信号的特点，对小波变换用于声发射信号的特征分析问题进行了研究，总结出了适用于声发射信号的小波变换信号特征提取方法，并对未来小波变换在声发射领域的应用与研究方向进行了探讨。

Abstract: Acoustic emission signal processing is the only effective method to acquire the acoustic emission source information by now and is also the bottleneck that affects its positive development. According to the characteristic of acoustic emission signal, a wavelet-based method of signal feature analysis was presented. The developing tendency of the application of wavelet transform in acoustic emission was discussed finally.
