摘要
采用数值模拟与试验检测相结合的方法对ACFM系统的电磁兼容性进行预测与分析,在应用有限元方法分析ACFM主要干扰源、评定电磁耦合途径的基础上,通过将相位特性引入敏感度分析模型,提出一种考虑相位特性的ACFM特性的敏感度评价模型,实现对ACFM检测系统的电磁兼容性预测,有助于改善结构物缺陷损伤检测精度。
The paper presents an analysis of the eleetromagnetic compatibility in ACFM inspection system, which is based on both numerical simulations and experiments. The main interference sources and eleetromagnetic coupling paths for ACFM are investigated by applying ANSYS system. A new sensitivity assessment model considering phase characteristics is established, and the EMC of ACFM system is predicted, which is helpful for detecting cracks in structures accurately.
