| Abstract: | The high detection efficiency of eddy current array detection technology makes it suitable for large areas scanning.Based on a systemic research on the eddy current array detection device developed independently,the theoretical basis of this work was studied for further applications,and simulation analysis with the FEM software COMSOL was carried out on the system.The simulation results show that,the estimating of surface crack defects on the conductor can carry out quickly and effectively.The eddy current array detection method plays a significant part in the evaluation of crack defects,can promote the technology development and practical efficiency of actual cracks detection. |
