潜艇腐蚀防护数值仿真评估研究

Evaluation research on numerical simulation of submarine corrosion protection

文章以潜艇为研究对象,利用数值仿真平台,采用边界元法计算潜艇在消声瓦不同状态下的电流阴极保护的情况,通过艇体表面单元的现有电位和目标电位之差的平方作为目标方程,以获得其最小值来实现艇体表面电位最优分布设计。结果表明,优化设计后的艇体均得到了有效保护。

This paper takes submarine as an object of study.According to the numerical simulation platform,the Boundary Element Method(BEM) is applied to calculate current cathodic protection under different conditions of anechoic tile.Through the objective function defined as a square of the relative error between existing potential on submarine hull surface unit and target potential,a minimum value will be obtained to realize optimal potential distribution design.The results show that the optimization designed submarine hull has been effectively protected.
