| 摘 要： | 舰载设备的磁性是现代反水雷舰艇磁场特征的主要来源，舰载固定设备产生的磁场可以通过舰载消磁线圈进行补偿，但是舰载活动设备，如舰载吊车等的位置和状态都是变化的，其所产生的磁场特征需要进行评估。以一座虚拟的舰载吊车为例，将其看作是由形状和厚度不一的铁磁薄钢板构成的，采用薄板情形的积分方程法分别计算了其在地磁场作用下处于收起状态和工作状态时的感应磁场分布。计算结果表明：舰载吊车产生的干扰磁场的峰值和变化值都是一个显著的磁场幅值，对全船感应磁特征的贡献足不可忽略的；并且这种磁场难以通过舰载消磁线圈进行补偿，建议采用低磁材料建造此类设备。

| Abstract: | The magnetism of shipborne equipments is the main source of magnetic signature of mine countermeasures vessels.The magnetic fields of shipborne static equipments can be compensated with degaussing coils,but that of shipborne moving equipments,e.g.shipborne crane,need to evaluate based on varying position and pose. Taking a fictitious shipborne crane composed of ferromagnetic thin steel sheets with different shapes and thicknesses,its induced magnetic field distribution in operational and stowed positions un... |
