一种基于交流电磁场的差分检测探头
A differential detection probe based on alternating current field measurement
摘 要
交流电磁场检测技术近年来广泛应用于各类结构缺陷的无损检测和定量评估中，检测时探头抖动易引起干扰信号而造成的缺陷误判，为解决此问题，提出一种新型的差分检测探头。通过COMSOL软件建立交流电磁场检测探头的有限元仿真模型，探究了提离抖动下特征信号的畸变规律，分析了Bx背景磁场与检测位置的关系；设计了一种基于差分磁传感器的检测探头，搭建缺陷检测系统并进行试验。试验结果表明，提出的差分检测探头能有效抑制提离干扰，增强缺陷信号识别能力，提高检测灵敏度。

Abstract
In recent years, alternating current field measurement (ACFM) technology has been widely used in non-destructive testing and quantitative evaluation of various structural defects. In order to solve the problem of misjudgment of defects caused by interference signals caused by probe jitter during defect detection, a novel differential detection probe is proposed. A finite element simulation model of ACFM probe is set up by COMSOL. The distortion law of the characteristic signals under lift-off jitter is investigated. The relationship between the Bx background magnetic field and the detection position is analyzed. Further, a probe based on differential magnetic sensors is designed. A defect detection system is built and related experments are carried out. The experimental results show that proposed differential detection probe proposed in this paper can effectively suppress the lift-off interference, enhance identification ability of the defect signals, and improve the detection sensitivity.
