Abstract—

The experimentally estimated effect of a waveguide on the acoustic emission signal parameters in the monitoring of high-curvature facilities has been studied. The frequency characteristics of the acoustic emission signals when passing from the pipeline to the waveguide remain almost unchanged, and the attenuation of the acoustic emission signals is no more than 2–3 dB.

曲率长半径监测设备中波导对声发射信号参数影响的实验估算

摘要-

在高曲率设备的监测中，研究了波导对声发射信号参数的实验估计影响。从管道到波导的声发射信号的频率特性几乎保持不变，并且声发射信号的衰减不超过2-3 dB。
