本文主要研究如何提高涡流无损检测中响应信号的信息量。研究中提出了一种新的涡流检测系统，以增强对指示缺陷的定量评价。它由三个相互垂直放置的圆形电感线圈组成。该系统允许感应扰动电磁场的所有三个空间分量。这样就获得了关于被检查缺陷的更复杂的信息。进行了数值模拟，并对结果进行了评估，以证明新系统在减少涡流无损检测中裂纹尺寸的模糊性方面的能力。
The paper focuses on increasing information level of response signals in eddy-current non-destructive inspection. A new eddy-current detection system is proposed in the study for enhancing quantitative evaluation of an indicated defect. It is composed of three circular inductance coils positioned perpendicularly to each other. The system allows sensing all of the three spatial components of the perturbation electromagnetic field. Thus more complex information about an inspected defect is gained. Numerical simulations are carried out and the results are evaluated to demonstrate capabilities of the new system in reducing the ambiguity of crack sizing using eddy-current non-destructive inspection.
