摘要
Abstract
Aiming at the problem that traditional eddy current testing is difficult to detect deep hidden defects in planar metal conductor sheet due to skin effect,a magnetic field energy gathering method based on far field eddy current was proposed for deep defects detection.Firstly,a far-field eddy current testing model of flat conductors is established,and the effects of various magnetic cores and magnetic shielding structures on eddy current energy are simulated and analyzed,and the magnetic cores and magnetic shielding structures in the far-field eddy current testing system of ferromagnetic flat conductors are optimized.Secondly,a shield with different material combinations is made and a far-field eddy current testing platform for flat conductors is built.Simulation and experimental results show that the double-layer magnetic shielding far-field eddy current probe structure with copper inside and sili-con steel outside can effectively enhance the energy of the indirect coupling channel and have strong ability of deep defect detection on the premise of guaranteeing the near far-field region.关键词
