摘要
针对舰船磁场建模问题进行研究,利用磁偶极子阵列对舰船磁场进行建模,并对舰船磁场磁偶极阵列模型的适用性进行分析。首先,建立舰船磁场磁偶极子阵列模型,将舰船磁场等效为一列均匀分布在舰船吃水面中线上的磁偶极子阵列模型;然后,基于磁偶极子阵列构造了舰船磁场建模数学模型,给出了磁偶极子阵列模型求解方法;最后,提出了舰船磁场磁偶极阵列模型适用性分析方法。对三种不同舰船船模进行了建模试验,计算不同偶极子个数的磁偶极子阵列模型的建模相对误差,得到舰船磁场磁偶极子阵列模型的建模规律,试验结论为舰船磁场建模和水中兵器的被动磁定位研究等工程应用提供了磁偶极子阵列模型选择参考依据。
In order to solve the problem of ship magnetic field modeling,magnetic dipole array was used to model the ship magnetic field,and the applicability of magnetic dipole array model for ship magnetic field was analyzed.Firstly,the model of ship magnetic dipole array is established,and the ship magnetic field is equivalent to a series of magnetic dipole array models distributed uniformly on the midline of the ship’s water surface.Then,based on the magnetic dipole array model,the mathematical model of ship magnetic field modeling is constructed,and the solution method of magnetic dipole array model is given.Finally,the suitability analysis method of magnetic dipole array model for ship magnetic field is proposed.The modeling experiments of three different ship models were carried out,and the modeling relative errors of the magnetic dipole array model with different number of dipoles were calculated,and the modeling rules of the magnetic dipole array model of ships were obtained.The experimental results provide a reference basis for the selection of magnetic dipole array model for ship magnetic field modeling and underwater weapon passive magnetic positioning research.
