摘　　要：利用有限元方法,基于国际集装箱标模KCS船舶对船体感应磁场和尾流感应磁场进行了研究。结果表明:船体感应磁场的大小取决于船舶形状与测量位置;船体和尾流感应磁场的量级都为nT,在可探测范围内;尾流感应磁场在远场范围随距坐标原点的距离增加呈指数级衰减。In order to explore the spatial distribution characteristics of induced magnetic field caused by ship and ship wake,based on the international container model KCS ship,the hull induction magnetic field and ship wake induction magnetic field are systematically studied by using the finite element method.The results show that the magnitude of the induced magnetic field depends on the ship shape and measurement position;The magnitude of the stress magnetic field of the hull and tail is belongs to the detectable range;The wake induced magnetic field decays exponentially with the increase of propagation distance in the far-field range,and the attenuation speed is very fast.
