摘要
随着电磁探测技术的提高和电磁引信水雷的开发应用,腐蚀相关电磁场成为影响船舶隐身性能和安全性的重要因素。针对目前没有系统的关于船体无保护、外加电流保护和牺牲阳极保护导致的稳态电场和腐蚀相关磁场特征研究的现状,采用数值仿真技术模拟了上述3种条件下的稳态电场和腐蚀相关磁场特征。研究结果表明,不同保护状态导致的腐蚀相关电磁场具有各自特征,且外加电流导致的腐蚀相关电磁场最强,牺牲阳极保护次之,无保护时腐蚀相关电磁场最小。
Due to development of electromagnetic field detection technology and application of intelligent mine,corrosion related electromagnetic field has serious influence on stealth and safety of ship.In order to comparatively study the characteristics of electromagnetic field when there was no cathodic protection,the ship was protected by impressed current cathodic protection and sacrificial anode respectively.Computer simulation technology was tentatively used to calculate the strength of electric and magnetic field.Simulation results showed that corrosion related electromagnetic field has its own unique characteristics,and the electromagnetic field induced by impressed current cathodic protection was the strongest one,and the electromagnetic field induced by sacrificial anode was stronger than that when there was no cathodic protection.
