| 摘 要： | 为研究声发射信号经过各种不同接合界面的传输衰减特性,设计了声发射信号经过螺栓紧固联接面、大小界面接合面、焊接面、法兰连接面等四组典型接合界面传播时的模拟试验来分析研究其声衰减特性。试验结果为实际应用中分析不同接合界面对声发射信号衰减的影响提供了重要参考。

Experimental Study of the Transmission Characteristic of Acoustic Emission Signal through Several Typical Interfaces |
| |
| Abstract: | In order to investigate the transmission characteristics of the acoustic emission,four experiments such as the bolts connected interface,the big size and small size interface,the steel weld plate interface,and the flange structure interface have been designed and executed.The conclusion of propagation characteristics was obtained,which was an important reference value to detect complex-structured equipment by acoustic emission. |
