摘　　要：脉冲涡流检测技术(PEC)是一种新型的无损检测技术。为增强对带包覆层管道壁厚的检测效果,需对PEC探头的参数进行分析选取,提高探头的检测精度。本文旨在分析探头在不同参数下对壁厚检测的影响,首先利用仿真软件建立数学模型,其次对探头的参数进行了仿真,并利用特征信号进行了分析。仿真结果表明:线圈参数与检测效果之间存在关联规律,通过在线圈内部加入磁芯,可以显著提高检测的灵敏度。Pulse Eddy Current Testing(PEC)is a new type of non-destructive testing technology.In order to enhance the detection effect of pipeline wall thickness with a coating layer,it is necessary to analyze and select the parameters of the PEC probe to improve the accuracy of probe detection.This study aims to analyze the influence of probes on wall thickness detection under different parameters.Firstly,a mathematical model was established by using simulation software.Secondly,the parameters of the probes were simulated and analyzed using characteristic signals.The simulation results indicate that there is a correlation between coil parameters and detection performance.By adding a magnetic core inside the coil,the sensitivity of detection can be significantly improved.
