基于磁体模拟法的舰船磁场补偿技术

针对舰船消磁系统快速准确解算、通用性强的设计要求,以磁体模拟理论为基础,提出了基于磁体模拟法的舰船磁场补偿技术.通过将舰船磁场补偿问题转换为求解若干反向等效磁源的磁矩,建立一种通用数学模型来实现消磁过程,并在此基础上形成满足实际应用需求的简化模型.将船模实测数值与仿真结果进行反向比对,表明在垂向磁场补偿方面,通用数学模型与其简化模型所取得的磁场补偿效果十分接近,但简化模型的解算速度较快,更能满足工程实用要求.

A magnetic field compensating method based on the magnet simulation theory for vessel

Aim at the requirements of accuracy,speediness and applicability in vessel's degaussing process,a magnetic field compensation method is presented based on the magnet simulation theory. A universal mathematical model is formulated by translating the vessel's magnetic field compensating problem into solving the magnetic torques of some equivalent magnets which can counteract the vessel's magnetic field. On the basis of it,a simplified model is brought forwards for satisfying the actual application. The simula...
