摘要: 为满足消磁勤务要求,需对导体涡流磁场相位滞后进行研究计算,从而更好地实现导体磁性补偿。该文提出一种基于磁变模拟法的涡流磁场相位滞后角的计算方法。首先,通过理论推导得到涡流磁场相位滞后角的计算方法;其次,在COMSOL仿真软件中,通过磁变模拟法在导体空间中施加外部激励磁场,其仿真结果和理论计算较吻合,平均误差百分比为0.025%;最后,为验证其理论计算和仿真结果的准确性,开展了涡流磁场测量实验,实验结果的平均误差百分比为2.48%,可满足工程要求。通过仿真分析和实验验证,证实该方法能准确快速地计算出不同频率的涡流磁场相位滞后角,并运用于实际工程计算中。

Abstract: To meet the degaussing service requirements, the phase lag of the eddy current magnetic field in conductors needs to be studied and calculated for better magnetic compensation of conductors. A method for calculating the phase lag angle of the eddy current magnetic field in the conductors has been proposed based on magnetic variation simulation method. Firstly, the calculation method of the phase lag angle of the eddy current magnetic field in the conductors is deducted theoretically. Subsequently, the external excitation magnetic field is applied in the conductor space by using the magnetic variation simulation method in the COMSOL software, and the simulation results are consistent with theoretical calculations with an average error of 0.025%. Finally, the eddy current magnetic field measurement experiment is carried out to validate the accuracy of the theoretical and simulation results, with an average error of 2.48%, satisfying engineering requirements. The simulation analysis and experimental validation therefore show that this approach enables rapid and precise calculations of the phase lag angle of the eddy current magnetic field at different frequencies, which can be used in practical engineering calculations.
