【摘要】 舰船的磁场与舰船所用的材料有关,同时也与舰船的消磁状况,所在地域的地磁场强度、舰船的航行方向有关,为较为真实地模拟现代舰船的磁场,在不考虑舰船运动过程中舰船因海浪的起伏而产生的横摇、纵摇、垂荡等运动状态的情况下,以偶极子方式建立舰船磁场模型,以北东系为参考坐标系建立舰船的运动模型,以舰船的实际尺寸作为划分偶极子数量的依据,建立了运动舰船的磁场模型。通过设置与实际舰船一致的舰船尺寸参数且选择合理的磁矩参数,不考虑地磁场影响,以数学仿真方式给出了舰船在在不同的方位、速度工况下,在指定深度位置处的磁场变化情况,并对相关数据结果进行了分析。最后结合半实物仿真试验的结果,给出了现代水雷磁引信系统对仿真磁场信号的响应情况及分析结果。更多还原

【Abstract】 The magnetic field of ship relates to the material,the degaussing status,the geomagnetic field intensity,and the course. For simulating the magnetic field of modern ship,on the condition that without regards to the rolling,the pitching,and the heaving produced by the ocean wave in the process of ship’s motion,this paper establishes the magnetic field model of ship in dipoles mode,the motion model of ship making the northeast coordinate system as reference coordinates,and the magnetic field model of motion ship using the actual size of ship as the basis for dividing dipolesquantity. Through setting parameters of ships size in accordance with actual ship and choosing the reasonable magnetic moment parameters,without regards to the influence of the geomagnetic field,this paper presents the change status of the ships magnetic field in deferent azimuths and velocities using the mathematical simulation,and analyzes correlative data results. Finally,the influence of the magnetic fuze system of modern mine on the simulation of magnetic field signal and its analysis results are given combing with the results of hardware-in-loop simulation test.更多还原
