潜艇在使用防腐保护系统时会产生水下电位(UEP)信号。而这些信号可以被敌方舰船检测到,这是防腐保护所带来的不良后果。德国舰船与海军武器技术中心(WTD71)与杜伊斯堡-埃森大学的 General and Theoretical Electrical Engineering(ATE)实验室合作研究了这些 UEP 信号以减少它们。

研究团队使用 COMSOL 模拟了潜艇船体的电位分布,研究材料是否具备防腐作用。结果表明,电位越高,船体越不会受到腐蚀。然后,他们模拟了不同电位留下的信号。公认的观点是腐蚀量越高信号越容易检测,大多数情况下是这样的。此外,分析结果表明,信号实际上是在零腐蚀防护和全腐蚀防护的标准运行条件之间最不易被检测到。
