| 摘要: |
| 基于等效偶极子法,从补偿偶极子长度、角度、大小三方面给出了任意角度的补偿偶极子场解析式,再利用电荷矢量叠加原理,建立了“腐蚀偶极子+补偿偶极子”电场模型。仿真以单轴桨船为例,先验证“腐蚀偶极子+补偿偶极子”电场模型的正确性,再进行补偿偶极子对舰船电场的影响验证,从而得出补偿最优解。模拟实验结果表明,补偿阳极在工程允许条件下距离补偿系统接船端最远处,且补偿系统平行于水平面和船体时补偿效果最优；在补偿最优条件下,理论上是可以抵消原舰船腐蚀电场的。 |

| Abstract: |
| Based on the equivalent dipole method, the analytical formula of compensation dipole field was given from the length, the angle and the size of compensated dipole. The electric field model of “corrosion dipole + compensation dipole” was established by using the principle of charge vector superposition. The simulation was taken to verify the validity of the “corrosion dipole + compensation dipole” electric field model, then to verify the influence of the compensate dipole on the ship′s electric field, finally the optimal solution was obtained. The test results show that compensation effect is the best when the compensation anode is farthest away from the terminal of compensation system, and the compensation system is parallel to the horizontal plane; as well as the original ship corrosion electric field can be offset theoretically under the compensation optimal condition. |
