摘　　要：针对潜艇电场防护补偿阳极电流的合理性输出问题,对潜艇模型进行数值仿真计算和数据拟合处理后,提出了一种获得最佳补偿电流输出的方法。该方法以补偿电流为自变量,船体表面电位、水下静电场为因变量,通过建立补偿电流与船体表面电位、水下静电场的函数关系,得到船体表面电位分布均匀时或水下静电场函数出现极小值时,补偿阳极输出电流即为最佳补偿电流。仿真结果表明:函数关系与船壳破损位置、船壳破损数目、补偿阳极位置、补偿阳极数目无关,只与补偿阳极输出的总电流大小有关。Aiming at the problem of reasonable output of compensation anode current in submarine electric field protection,a method to obtain the best compensation current is proposed through numerical simulation and data fitting of submarine model.This method takes the compensation current as the independent variable,the hull surface potential and the underwater electrostatic field as the dependent variables.By establishing the functional relationship between the compensation current and the hull surface potential and the underwater electrostatic field,it is obtained that the corresponding anode output current is the best compensation current when the hull surface potential distribution is uniform or the underwater electrostatic field function has a minimum.The simulation results show that the function relationship has nothing to do with the position of hull damage,the number of hull damage,the position of compensation anode and the number of compensation anode,but only with the total output current of compensation anode.
