磁场运动速度对动生涡流热成像的影响
|
摘要
动生涡流热成像是利用导电试件切割磁力线产生的动生涡流作为热激励的新检测方法。通过电、磁、热多物理场耦合仿真方法和高速热成像检测试验,对不同深度缺陷在不同磁场运动速度下的热响应进行了研究。仿真和试验结果表明,在不同运动速度下缺陷产生了明显的热响应差异,速度越快,趋肤效应越强,靠近工件表面的缺陷的检测效果更明显。
Motion-induced eddy current thermography is a new nondestructive method,which utilizes the eddy current created by relative motion between conductive specimen and magnetic field.In this paper,the thermal response of defects with different depths at different speeds was studied by multi-physical coupling simulation and high-speed thermography experiment.The simulation and experiment results show that the defects at different moving speeds have obvious differences in thermal response,and the faster the speed is,the more obvious the detection effect is while the defects being near the surface of the workpiece.
