摘　　要：为了减少舰船腐蚀电场对船上电磁通信设备的干扰,需要对舰船腐蚀电场进行抑制或消除.采用三维边界元法建立潜艇腐蚀静电场模型,研究补偿阳极位置对腐蚀电场防护效果的影响,结合电偶极子模型理论解释了静电场防护原理,基于静电场防护原理,分析不同补偿阳极位置产生舰船腐蚀电场差异的原因.结果表明:补偿阳极的周向位置对电场防护效果影响较小,而纵向位置对电场防护效果有明显的影响;补偿阳极与螺旋桨的纵向距离分别为16.6、10.8、5、1 m时,电场模量的防护效果分别为3.41%、24.88%、49.27%和34.15%.To reduce the interference of corrosion electric field of ship on electromagnetic communication equipment,it is necessary to suppress or eliminate the corrosion electric field.A submarine corrosion electrostatic field model was established by using the three-dimensional boundary element method(3 D-BEM)to investigate the influence of compensation anode positions on the electric field damping effect.The principle of electrostatic field damping was explained based on the electric dipole model theory,and the reasons for the difference in corrosion electric field of ship with different compensation anode positions were analyzed.Numerical simulation results show that the circumferential position of the compensation anode had little influence on the damping effect,while longitudinal position had significant influence on the damping effect.In addition,when the longitudinal distance between compensation anode and propeller was 16.6 m,10.8 m,5 m,and 1 m,the damping effect of the electric field modulus was 3.41%,24.88%,49.27%,and 34.15%,respectively.
