基于规范的牺牲阳极阴极保护优化设计方法

Optimal Design Method of Sacrifi cial Anode Cathodic Protection Based on Specifi cations

牺牲阳极阴极保护设计缺乏针对单块阳极形状尺寸和整体方案的优化方法。为解决此问题,首先引入细长系数和扁平系数的概念;然后基于规范推导无涂层时牺牲阳极形状尺寸与所需牺牲阳极总数量和总质量之间的关系;接着利用结构物的极化要求和牺牲阳极材料的消耗要求等确定牺牲阳极形状尺寸的可行域;最后结合经济性指标建立完整的优化问题模型并给出求解方法。此优化设计方法能够确定牺牲阳极形状尺寸和获得经济性最优的整体方案。

The design of sacrificial anode cathodic protection lacks optimization approaches for the dimensions of single anode and the overall scheme.The concepts of slenderness and flatness are firstly introduced to solve this problem.The relationship between the dimensions of the sacrificial anode without coating and the total quantity and the mass of the required sacrificial anode is deduced based on the specifications.The feasible region of the dimensions of the sacrificial anode is then determined according to the polarization requirement of the structure and the consumption requirement of the sacrificial anode material.Finally,an integrated optimization model is established with the economic index in order to give the solution.This optimal design method can determine the dimensions of the sacrificial anode and get the general scheme with the optimized economy.
