摘要
声发射技术在滚动轴承的检测中得到了广泛应用,声发射信号处理是检测中的关键技术问题,常用的声发射信号处理技术有参数分析、波形分析、小波分析、模式识别等等。综述了21世纪以来声发射信号处理技术在滚动轴承检测中应用现状,国内外学者在将各种声发射信号处理技术应用于滚动轴承检测方面做了大量研究且取得了一定程度上的研究成果。需要进一步研究的内容是规范各种工况下声发射信号处理方法并设计标准的声发射信号处理平台。
Acoustic emission technology is widely used in rolling bearing test, while the processing technology of acoustic emis- sion signal is essential to the test. The common acoustic emission signal processing technology includes parameter analysis, waveform analysis, wavelet analysis, pattern recognition, etc. This paper gives an overview of acoustic emission signal pro- cessing technology in rolling bearing test since year 2000. A lot of research and achievements have been made in the field. And it shows further study should focus on regulating acoustic emission signal processing methods under various working condi- tions, and the designing of standard acoustic emission signal processing platform.
