模拟舰船磁场的两轴磁体设计研究

Design and Research on Two-axis Magnet for Simulating Ship Magnetic Field

为提升磁体模拟舰船磁场的相似性、提高舰船磁场模拟的效率,提出一种两轴磁体的设计方法。在同一个磁芯上同时绕制两种形式的线圈,并分别通入独立的电流,用以产生两个相互独立的垂直方向磁场,同时模拟舰船磁场的多个分量,从而模拟整个舰船磁场。按照现有约束条件确定两轴磁体的材料、尺寸、线圈绕组圈数等设计参数,并按10∶1的比例制作缩比磁体模型,对磁体模型的磁场进行实验室测量。测量结果表明,采用基于双绕组、单磁芯的两轴磁体可有效模拟舰船磁场的多方向特征。

A two-axis magnet simulation scheme is proposed to improve the similarity of magnet used to simulate the ship's magnetic field.Wire coil and saddle coil are wound on the same core.The separate currents are used to generate two magnetic fields perpendicular to each other to simulate the ship's magnetic field.The design parameters of material,size,number of laps of coil winding are determined under the operating requirement on the ship.A physical model was made at the ratio of 10:1.The magnetic field of physical model was measured.The experimental results show that the two-axis magnet with duplex winding and single can effectively simulate the characteristics of ship's magnetic field.
