| Abstract: |
| By comparing and analyzing the technical principles and design examples of pulsed eddy current probe without disassembly in foreign countries, and aiming at the parameters of probe in existing literatures, the upper and lower gradient simulation is carried out, and a targeted optimization design method of probe is proposed. Through theoretical calculation and numerical simulation, the sensitivity is taken as the optimization index to obtain the optimal diameter and height data of the transmitting coil. Through numerical simulation and calculation, the optimal line diameter and the optimal number of turns of the transmitting coil are obtained. The optimal diameter and number of turns of receiving coil were obtained by numerical simulation. Through practical test and orthogonal experiment, the optimal line diameter and turn number of transmitting coil and receiving coil are obtained. According to the finite element model. The parameters of the pulsed eddy current insulation probe are optimized in a certain range. The results show that the optimal design method of the probe based on theoretical calculation and numerical simulation is feasible for the probe of a particular pulsed eddy current system. |
