本文介绍了声发射监测仪器的一般构成和国内声发射监测仪器的发展情况,以及SFS-4四通道声发射信息分析仪的设计思想和实验效果。该仪器首次采用“自动门槛”、“加权振铃”等国外新型声发射仪器的最新处理技术,增加了许多新的表征参数,大大提高了仪器的抗干扰能力和应用范围,文章还进一步讨论了今后声发射仪器的发展方向。
This article describes the general structure of acoustic emission monitoring instruments and the development of domestic acoustic emission monitoring instruments, as well as SFS-4 four-channel acoustic emission information analyzer design ideas and experimental results. The instrument for the first time using “automatic threshold ”, “weighted ringing ” and other foreign new type of acoustic emission equipment, the latest processing technology, adding a number of new characterization parameters, greatly improving the instrument’s anti-interference ability and application range, the article Further discussion of the future development of acoustic emission instruments.
