Numerical Value Analysis of Eddy Current Probe Coil of Placement Model Based on ANSYS
Eddy Current Testing (ECT)is a universal testing method, which is widely used in many fields. Thickness measurement is an important application of ECT. In this paper, numerical simulating by ANSYS finite element analysis software, the two-dimension model of ECT probe coil is built, the impedance variation of probe coil is acquired, and normalization to the impedance value of the probe coil is realized, according to the variation of thickness of nonconductive cladding over nonmagnetic metal substrate and thickness of metal substrate. The calculated simulative result is coincident with the traits of the real transducer. Thus, an effective analysis method and reference basis is consequently offered for the research of ECT theory, transducer design and practical application.
