高速检测条件下缺陷钢轨涡流效应的仿真
Simulation Research of Defective Rails Eddy Current Effect in High Speed Detection
摘 要
由于高速漏磁检测下速度效应的存在，检测信号会发生畸变。根据漏磁检测中速度效应的基本原理可知，速度感应产生的涡流是直接影响漏磁检测信号的因素之一，而且其大小同速度及磁场强度成正比。因此文章根据高速检测的这一特点，建立了新的高速检测模型，对一系列运行在不同速度下有缺陷的钢轨模型进行了有限元仿真，并将该模型下的检测信号与经典漏磁模型的检测信号对比，进一步认识了涡流效应对检测信号的影响。

Abstract
The velocity effect of MFL inspection under high speed induces the distortion in the detection signal. According to the basic principle of velocity effect on MFL inspection, it showed that eddy current induced by velocity is one of the factors which influence the MFL signal directly and the size of eddy current is proportional to velocity and magnetic field intensity. In this paper, a new model of high speed inspection was produced based on this characteristic. Different finite element analysis were used for the defective rail module. Detection signals of this module were compared with the signal from the classical magnetic leakage module. The effect of the eddy current was deeply studied.
