摘　　要：磁体模拟法是用若干具有特定磁矩的磁源所产生的磁场来模拟舰船磁场,对于舰船消磁系统,可以构造一些特定磁源,使其产生与舰船磁场大小相等、方向相反的磁场,通过对这些磁源的补偿作用,就能抵消掉舰船的感应磁场,从而达到消磁目的。经过仿真验证,证实了磁矩分离数学模型的准确性,因此可根据此数学模型分离出的感应磁矩来调整消磁绕组的位置,计算消磁绕组电流,就可使舰船磁矩得到抵消,从源头上对舰船磁场进行控制。Magnet simulation method is used to simulate warship＇ magnet field with magnet field produced by magnetic fountain which has special magnetic moment.Aim at warship＇ degaussing systemi,f we can construct some special magnetic fountain,which produce reverse magnet field of equivalence.Compensate effect of magnetic fountain is used to counteract warship＇ induced magnetic field in order to reach degaussing purpose.Via simulation validationt,his math model＇ nicety is approved.This paper calculate the degaussing winding＇ electric current with separated induced magnetic moment,warship＇ magnetic moment is compensated by changing currentt,herefore,warship＇ magnet field is controled from headstream.
