摘要
为了达到最大程度减少舰船静电场的目的,在利用边界元数值仿真软件的基础上,对比分析了自然腐蚀状态、牺牲阳极保护、外加电流阴极保护优化和外加电流补偿四种状态下的船体电位及水下静电场特性.结果表明,基于外加电流补偿的方法能有效降低舰船静电场,但是仅船体尾部和螺旋桨附近处于阴极保护状态.为了兼顾防腐与隐身的要求,提出"平时"采用外加电流阴极保护优化技术和"战时"采用外加电流补偿技术的静电场隐身方法.
In order to reduce ship electrostatic field to the greatest extent,the hull potential and underwater electrostatic field characteristics are compared and analyzed based on boundary element calculating software under four different conditions,natural corrosion,sacrificial anodes protection,advanced impressed-current cathodic protection and impressed-current compensation.The results show that the method based on impressed-current compensation can effectively decrease ship electrostatic field,but only the areas near ship tail and propeller are under cathodic protection.In order to realize the needs for anti-corrosion and stealth in electric field,the advanced impressed-current cathodic protection method is proposed for daily use and the impressed-current compensation method proposed for wartime use.
