舰船水下静电场防护因素的仿真分析研究

Simulation Analysis of Protective Factors of Submarine Electrostatic Field of Ships

舰船的静电场防护直接影响舰船在作战时的隐身性能。本文重点分析了影响舰船水下静电场防护的主要因素,采用边界元法建立某潜艇腐蚀静电场模型和外加补偿电流后的防护电场模型,研究了不同补偿电极位置、不同的补偿电流接地点位置及补偿电流和腐蚀电流比值系数变化对舰船静电场防护效果的影响。结果表明,补偿电极位置越靠近螺旋桨,以及补偿电流接地点位置越靠近船体破损点(阳极),舰船水下静电场防护效果越好,防护效果最好时的比值系数K值的范围为(1~1.25)。

The electrostatic field protection of ships directly affects the stealth performance of ships in combat.This paper focuses on the main factors affecting the submarine electrostatic field protection.The boundary element method is used to establish the corrosion electrostatic field and external compensation current model of a certain type of submarine.The influence of the position of compensation electrodes,the position of compensation current earth point and the ratio of compensation current to corrosio n current on the protection effect of the ship's electrostatic field are studied on.The results show that the closer the position of the compensation electrode is to the propeller,and also the closer the position of the compensation current earth point is to the rupture point(anode)of the ship,the better the protection effect of the ship's electrostatic field,with the best range of the value K fallen between 1-1.25.
