| 通过比较分析国外脉冲涡流不拆保温探头的技术原理和设计范例，针对现有文献中探头的参数，进行上下梯度模拟，提出具有针对性的探头优化设计方法。通过理论计算和数值模拟，取灵敏度为优化指标，得到最优发射线圈的直径与高度数据；通过数值模拟和计算求解，得到发射线圈最优线径和最优匝数；通过数值模拟得到最优的接收线圈线径和匝数；通过实际测试和正交试验，得到实际应用化的发射线圈最佳线径和匝数，以及接收线圈的最佳线径和匝数。依据有限元模型，脉冲涡流不拆保温探头的参数在一定范围内都进行了优化。针对特有脉冲涡流系统的传感器探头，依据现有文献中参数进行理论计算和数值模拟提出的探头优化设计方法是可行的。 |

| 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. |
