均匀密绕消磁线圈对坦克磁场影响效应的数值计算分析

Calculating and Emulation for Infective Effection about Magnetic Field of Tank with Hollow Sphere Structure Being Closely Circled by Degauss Loops

通过数值处理和计算机模拟,得出一种排布方式的消磁线圈对坦克磁场的影响效应分布,即当消磁线圈为同轴均匀密绕情形时,线圈内部为匀强磁场,方向沿通电线圈的轴向,且与通电电流成右手螺旋关系,线圈外部为偶极子场,该场会随着与线圈中心距离的增大而迅速减小。仿真结果对封闭型军事装备表层安装消磁线圈的方法给出一点参考,通过分析消磁线圈附加磁场的特点对装备磁防护理论提供一些支持,提供了计算轴对称均匀密绕线圈磁场的一种方法。

A kind of infective effection about magnetic field of tank with hollow sphere structure being closely circled by degauss loops is discussed by numerical value disposal and computer emulation. When＇. the degauss loops are closely circled with the same axis, it is an even-poles magnetic field outside the tank which will minish lastly with the distance＇ s accretion;while it is an even magnetic field inside the tank whose direction is along the loops＇ axis, by the dextral relation with the electrical current in loops. Some images are created with calculation and emulation on computer. These datas and images are useful for arms＇ electromagnetism with closed-end structure. An approach for calculating magnetic field of the sphere being closely circled by degauss loops with the same axis is provided.
