摘要
为了研究舰船轴频电场的建模,在麦克斯韦方程理论基础上推导了两层介质中水平时谐电流在本层介质中产生的磁矢量势公式和时谐电场三分量公式,并通过数值方法仿真分析了海水中水平时谐电流产生的电场三分量的分布特性.通过将仿真结果与实验室船模轴频电场测量数据对比表明,舰船轴频电场分布特性与水平电流所产生的电场分布特性相似,因此可以由时谐电流电场的叠加来对舰船轴频电场建模.
In order to model the ship′s shaft-rate(SR) electromagnetic(EM) field,this paper deduced the electric field equations in two-layer medium.With numerical methods,the distribution characteristic of the SR electric field has been analyzed.The experimental data of ship model indicated that the ship′s SR electromagnetic field can be modeled by cumulating time-harmonic currents′ electric field.
