Research on Acoustic Emission Signal Acquisition and Acoustic Source Identification of Tank Floor Corrosion

QIU Feng, DAI Guang, ZHANG Ying, ZHAO Yongtao, LI Chengzhi


Based on the acoustic emission source location theory of tank bottom, the sensor located among the medium inside the tank is put forward, which could identify the acoustic source of tank bottom corrosion defects together with the sensors which are arranged on tank outside wall near tank bottom, and thus the reliability of acoustic emission source location technology on the tank bottom can be increased. Location experiment of simulative tank bottom, attenuation characteristic experiment of simulative tank and acoustic source identification experiment of simulative tank bottom corrosion have been conducted. The results present that the method of acoustic source identification and location could enhance the identification of acoustic source in arbitrary triangle location, increase the area of the tank bottom zone location, decrease the missing signals caused by acoustic attenuation, at the same time, the sensors inside tank are more sensitive to acoustic source of corrosion than that outside tank, and reduce the influence caused by weather and other factors on acoustic source location. So the method can improve the reliability of acoustic emission source identification and location on tank bottom, provide theory and experiment foundation for acoustic emission testing evaluation of tank bottom.
