Simulation on the Defect Effect of Excitation Parameters Using Pulsed Eddy Current Testing
摘 要
脉冲涡流检测技术是一种新兴的电磁无损检测技术,激励参数与脉冲涡流检测灵敏度、涡流渗透深度密切相关,选择合适的激励参数十分必要。采用COMSOL有限元仿真软件建立了脉冲涡流圆柱型探头的有限元模型,分析了不同幅值、不同占空比以及幅值与时间的乘积相同的情况下,对金属部件表面下缺陷检测的影响。通过有限元仿真分析,提出增大激励幅值可以提高检测的灵敏度,增大占空比可以提高涡流的渗透深度的结论。该结论为工程实践金属内部缺陷检测提供了一定的参考价值。
Abstract
Pulsed eddy current(PEC) testing technology is a newly developed electromagnetic nondestructive testing technology, with its penetration depth and the sensitivity having a close relationship with excitation parameters, and therefore appropriate excitation parameters are very necessary. The finite model of circular probe using COMSOL is built on subsurface defect with different peak of excitation, different duty cycle of excitation and the same integral of amplitude on the time. After simulation, increasing the peak of excitation can get better sensibility and the duty cycle can decide the penetration depth through data analysis of Matlab. The conclusion will provide some references on subsurface defect detection.
