低磁性舰船涡流磁场计算及实时预测方法
Calculation and Real-time Prediction Method of Eddy Current Magnetic Field of Low Magnetic Ship
摘要
Abstract
In order to realize the numerical calculation of ship eddy current magnetic field and real-time prediction of eddy current magnetic field.The magnetic variation simulation method is used to convert the eddy current magnetic field caused by mo-tion into the eddy current magnetic field caused by variable magnetic field excitation.Based on Taylor series decomposition,the transient problem is decomposed into a series of more efficient steady-state problems,so as to realize the numerical calculation of ship eddy current magnetic field.Aiming at the problem of real-time prediction of eddy current magnetic field,the distribution law of eddy current magnetic field at different frequencies,depths and positions is analyzed,and a real-time prediction method of eddy current magnetic field based on linear interpolation is proposed.The numerical experiments show that the error of interpolation pre-diction results is within 8%,in which the maximum error of imaginary part is 8%and the maximum error of real part is 5%.Proper selection of interpolation frequency and frequency points can improve the interpolation accuracy,and the proposed prediction algo-rithm can be further extended to practical demagnetization service.关键词
