摘要
从舰船静态电场的物理特性出发,对其在深海环境下的深度换算方法进行研究,提出基于拉氏方程的静态电场深度换算方法.利用该方法可实现静态电场的某分量向较大深度处自换算;由场垂直分量向较大深度的其他分量互换算以及由水下标量电位向较大深度的电场各分量的换算.以单个水平电偶极子的场为计算原型,以互换算为例对换算方法进行了仿真验证,通过对换算误差的分析,表明该换算方法是可行的.换算方法对实际舰船的静态电场的分布研究具有现实意义.
Based on the in-depth research on the physical properties of the static electric field of ships,a kind of extrapolation method of the static electric field of ships in deep-sea environment is put forward based on Laplace equation.The self-extrapolation of each component of the static electric field and the mutual extrapolation from the vertical component and underwater electric potential respectively can be realized by this method.Then taking the mutual-extrapolation of the fields of single electric dipole for example,the extrapolation method is validated by simulation.The error of extrapolation is analyzed and the research results show that this method is feasible and has significance for the study of the distribution of the electric field of an actual ship.
