脉冲涡流热成像检测激励参数的优化
The Optimization of Excitation Parameters of Pulsed Eddy Current Thermography
摘 要
脉冲涡流热成像无损检测技术可以对金属表面裂纹进行快速、准确地检测，但是不同的激励参数和材料特性对检测结果影响很大。通过建立感应加热二维模型，选取了表面温升和温度升高比两个特征量，分析了铁磁性的45钢和非铁磁性的202不锈钢在加热时间和激励电流频率变化时的感应加热规律，比较了两种材料的涡流场、温度场分布的差异以及激励参数变化对裂纹检测的影响，为实际检测中铁磁性和非铁磁性材料脉冲涡流感应加热激励参数的选取提供了参考。

Abstract
The surface crack of metallic materials can be detected efficiently and accurately with pulsed eddy current thermography. The detect results are very different with the change of excitation parameters and physical properties of materials. In this paper, with the building of a twodimension model for induction heating, the surface temperature rise and ratio of temperature rise are chosen to analyze the induction heating rule of magnetic and nonmagnetic materials, that is, 45 steel and 202 stainless steel, as the excitation duration and frequency changes, then the differences of the distribution of eddy current and temperature and the results of various excitation parameters on crack detection between the two materials are compared, which provide a guidance to optimize the excitation parameters of ferromagnetic and nonmagnetic materials for practical detection.
