摘要
利用参数分析法的目的是为了有效准确的分析声发射信号的特性,常用的参数有振铃计数、能量、上升时间、脉冲持续时间、幅值分布、事件计数等。每个参数都可以提供与声发射信号特征相关的信息,在声发射信号分析中有着重要作用。
Aiming at effective and accurate analyzing acoustic emission signal characteristics,parameter analysis method was adopted. The general parameters include ring count,energy,rise time,pulse continuous time,crest value distribution and matter count,each parameter could offer corresponding information with acoustic emission signal characteristics and plays an important role on acoustic emission signal analysis.
