摘要
概述了如何降低舰船腐蚀等因素在海水中形成的电场信号。推导得到了舰船补偿阳极在海水中产生的电场强度解析式,并给出了数值仿真。进一步利用进化规划算法计算得到了将原始电场降至最低所需的补偿阳极电流最优值,比较了补偿前后的电场大小分布以及实际补偿效果与数值仿真结果。仿真和实验结果表明,舰船电场防护使船体周围海水中的电场明显减少,并验证了基于进化规划算法的补偿阳极电流计算方法的正确性和有效性。
How to reduce the ship corrosion electric fields was introduced in brief. The electric fields analytical expressions of compensatory anticathode in the sea were obtained and simulated. And the optimal current of compensatory anticathode was calculated by applying the evolutionary programming arithmetic, and the fore-and-aft electric fields and the actual effect of compensation with the simulation were compared. The simulation and experiment show that the electric fields around ship are reduced obviously, and prove the validity of the method based on evolutionary programming arithmetic
