Kurzfassung:
The skin effect exists on the surface of the cylinder workpiece, and the existing eddy current probes cannot detect the deep cracks in the forgings. In order to improve the detecting depth of eddy current, based on the principle of electromagnetic induction, the solenoid coil size, location, etc. The influence of parameters on the eddy current penetration depth, considering the solenoid coil exciting current frequency, current density, hoisting height of solenoid coil, coil width, the thickness of the coil and the solenoid coil distance plate specimen under test, test parameters, such as adopting ANSYS software of eddy current density under different parameters with numerical simulation, analyzes the solenoid coil used for deep crack detection accuracy, on this basis, the optimal design can be used for the deep crack detection of solenoid sensor structure, It is applied to the main shaft of forgings with artificial deep crack. The simulation results show that the combined solenoid probe can be used to detect deep cracks in cylindrical forgings.
