Optimization Design of Alternating Current Field Measurement Inducer

摘要: 利用交流电磁场检测试验台对交流电磁场检测设备的探头激励装置进行优化设计。选取U形磁芯结构的激励方式，对比分析磁芯材料、磁芯结构、激励线圈结构、激励电压等因素对检测效果的影响，完成激励装置的优化设计。使用设计的激励装置对4种尺寸的典型缺陷进行检测，验证了激励装置的检测效果，使裂纹检测的分辨率达到了3 mm。

Abstract: Optimization design of ACFM inducer is performed by using ACFM experimental platform. The U-shaped core is used to induce magnetic field, and the core material, core structure, induction coil structure and induction voltage is considered to achieve the optimized design of ACFM inducer. By numerous experiments, testing of 4 dimensions of typical defects is performed to verify the testing effect of the optimized ACFM inducer. The results show that the resolution of the carck detection reaches to 3 mm.
