Optimization of Eddy Current Sensor Parameters for Detection of Circumferential Crack in Small-Diameter Tube

  • 摘要: 为解决传统探头检测小径管周向缺陷时,易出现漏检或耗时长的缺点,设计了一款针对此类缺陷的涡流探头。通过有限元仿真和试验的方法对探头的几何参数进行优化,分析了磁性材料厚度、宽度,激励线圈线径以及匝数对小径管周向缺陷检测的影响,为优化探头检测性能提供参考。制作新型探头与传统涡流探头对标准缺陷进行检测试验,发现在检测周向缺陷时,制作的探头比常规探头的检测能力更强。
    Abstract: In order to overcome the shortcomings such as missing detection or long time consuming in the detection of the circumferential defects of the small-diameter tube by traditional probes, an eddy current probe for such defects was designed. The finite element simulation and experimental methods were used to optimize the geometric parameters of the probe. The influences of thickness, width of the magnetic material, diameter of the excitation coil, and number of turns on the detection of the circumferential defect of the small diameter tube were analyzed, which provided references for optimizing the detection performance of the probe. Compared the detection of standard flaws between the new type of probe and a conventional eddy current probe, it was found that the detection of circumferential defects by the former one is more powerful than that by the latter.
