介绍多传感器数据融合、时频能量模式分析及分形理论识别声发射源特征的方法,说
明基于波形分析的现代信号处理技术是揭示声发射源及信号传播规律的重要手段。
关键词:声发射检验;多传感器数据融合;时频能量模式;分形理论;信号处理
Abstract : The methods of multi2sensor data fusion , time2frequency2energy(TFE) pattern analysis and fractal theory for rec2 ognizing acoustic emission (AE) sources are described. Contemporary signal processing techniques are important to extract the characteristics of AE sources and the law of wave propagation.
Keywords :Acoustic emission testing ; Multi2sensor data fusion ; Time2frequency2energy pattern ; Fractal theory ; Signal pro2 cessing
