为了减小舰船静电场信号,在深入研究静电场产生机理的基础之上,提出了外加电流补偿的静电场抑制方法;并在大量Beasy仿真计算数据的基础上,确定了利用船体表面电位或者电流密度作为控制系统输入量的闭环控制方法;最后利用船模实验验证了所提方法的有效性。试验结果表明,对静电场的抑制效果可达80%以上。 In order to reduce the signal of the electrostatic field of the ship, based on the further study of the mechanism of the electrostatic field, a method of suppressing the electrostatic field with current compensation is proposed. On the basis of a large number of Beasy simulation data, Current density as a closed-loop control method for the input of the control system. Finally, the effectiveness of the proposed method is verified by the ship model experiment. The experimental results show that the inhibitory effect on the electrostatic field can reach more than 80%.
