| 摘 要： | 脉冲涡流矩形传感器是近年来涡流无损检测的研究热点。采用COMSOL有限元仿真软件建立了矩形探头有限元仿真模型,以电导率变化为变化因子,使用单因素轮换法对矩形探头的尺寸比例进行了优化设计。通过仿真实验和数据分析,得出矩形探头长宽高比例为2∶1∶1.5时,探头的灵敏度、线性度最佳。本仿真优化结论可为使用脉冲涡流进行矩形探头缺陷或应力检测提供参考。

| Abstract: | The rectangular probe used in pulsed eddy current nondestructive testing has received considerable attention in recent years. COMSOL finite element simulation software was employed to establish rectangular probe model. Optimization design of the rectangular probe dimensions was proposed by changing conductivity and using single factor rotates. The simulation results showed that the optimal dimensions radio was 2 ： 1 ： 1.5 in terms of sensitivity and linearity of rectangular probe. The conclusion would be helpful for design of practical pulsed eddy current probe. |
