摘要

在高压输电塔的锚杆顶端施加一瞬态激振力

由布设在锚杆顶端的声发射传感器接收反射的信号。对接收的声发射信号进行了时频分析和小波分析。通过对比可以看出

声发射信号的特征频率、能量与腐蚀的状况有很好的相关性。因此

声发射技术是一种可靠有效的检测高压输电塔锚杆腐蚀的方法。

Abstract

Apply the moment state force on the top of anchor of high-voltage transmission tower

acoustic emission（AE） sensor setting on anchor will recieve reflecting signal. Then the signal are analyzed by time-frequency analysis and wavelet analysis. It is found that there are clear correlation between the energy

characteristic frequency of AE signals and the corrosion of anchor. therefore AE technology can be used for the detection in transmission tower anchor corrosion.
