Simulation on Detection of Crack on Complex Geometry Components with Eddy Current Stimulated Thermography

  • 摘要: 脉冲涡流无损检测已成为零件表面和亚表面缺陷检测的重要手段之一。文章应用数值仿真方法,在COMSOL平台上模拟研究了复杂曲面零件的裂纹缺陷的脉冲涡流热特性,给出了在脉冲涡流作用下的裂纹缺陷周边温度场分布与变化规律。仿真结果表明,脉冲涡流热成像技术能有效检测复杂曲面零件的裂纹缺陷。研究成果可供检测系统设计作为参考。
    Abstract: Eddy current has become one of the practical approaches to detect surface and subsurface defects of magnetic component. Simulation method has been employed to explore the thermal characteristics of the defects on complex geometric component stimulated by eddy current via COMSOL software. The temperature distribution and its variation around the defect have been obtained. The results show that eddy current thermography could be efficient to inspect surface and subsurface defects in complex geometric component. This work could be a reference for designing inspection system to detect cracks in complex geometric component with eddy current stimulated approach.
