摘要
潜艇的金属壳体运动时,会因切割地磁场产生感应电动势,而产生感应静电场。分析了海水中水平电流线电场,在此基础上,将潜艇简化为圆柱形,建立基于水平电流线的感应静电场模型,获得了电场三分量表达式。以日本"苍龙"号潜艇为例进行了感应电场的仿真,分析了艇体上下方感应静电场。仿真分析结果表明,感应电场具有量值可测、分布特征明显的特性。
When a submarine moves across geomagnetic field, static electric field（SE） is induced in the metal hull. The electric field of horizontal current in seawater is analyzed. The submarine is treated simply as a metal cylinder hull, induced electrostatic field model is built, and three component expressions of electric field are obtained. Taking the submarine SOuryft（SSSO1） of JNSDF for example, the induced static electric field distribution under different water depths is calculated when the submarine is in submerged status. Simulation results show that the induced static＇ electric field of the submarine has apparent characteristics.
