摘要

声发射法是一种在运行过程中对材料、结构、生产控制和诊断进行分析的方法。与其他控制方法相比，它的重要优点是它只对即将到来的真正危险的缺陷做出反应，并且它能够扫描大面积或整个产品，而无需通过传感器进行扫描。采用基于频谱的相关系数和信噪比评估算法。本文介绍了在前期实验数据的基础上，对“Emiss-2”系统进行通信和声发射信号分析的程序开发结果。

Research of Acoustic Emission Signal Preprocessing and Application in Hearing Impaired

Acoustic emission method is used as a means of analysis of materials, constructions, productions control and diagnosis during operating time. It's important advantages over other control methods are that it only reacts upon upcoming really dangerous defects and its ability to scan large areas or the whole of product without scanning it by a transducer. The correlation and signal to noise ratio were evaluated by the algorithm based on frequency spectrum. In the article there are the results of program development for "Emiss-2" system communication and acoustic emission signals analyzing which is based on the earlier experimental data.
