LIU Dong-sheng, WAN Zhou. Application of acoustic emission technology in high-voltage transmission tower anchor corrosion detection[J]. 2017, 36(11): 158-160.
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.
