Defect Test of Metal Surface with Alternating Current Field Measurement Method

SUN Yu, LUO Fei-lu, ZHAO Dong-ming (College of Electromechanical Engineering & Automation, National University of Defense Technology, Changsha 410073, China)  
When an AC exciting coil is put nearly a test plate, a current will be induced by the Alternating Current Field. Based on the theory of Alternating Current Field Measurement method, a model of the direction of the induced current following in the plate is given, and the electromagnetic field is analyzed by divided in three directions, and also the detection and simulation of cracks in the metal surface is done with ANSYS. The simulation results shows that the cracks in the metal surface can be measured by measuring the distribution of the disturbed magnetic field.
