摘要
分析了引起声发射信号衰减的各种原因,采用美国PAC公司的声发射仪,对一个复杂特征管道中声发射信号的幅度衰减情况进行了试验测量,得出了不同管道特征对声发射信号幅度的衰减影响的结论,并提出相关的建议。
This article analyzed different reason for the amplitude attenuation of the acoustic emission, and used the AE testing device produced by PAC America to test the acoustic emission attenuation using a pipe with many complex features. Then it draw a conclusions that different pipes feature weaken the acoustic emission signal in different ways. At last, some relevant recommendations were put forward.
