The Research on Designing a Scale Ship Model Based on Cathode Protection

Cathode protection is a common ship electric protection method, a large number of researchers studies cathode protection by making appropriate ship models and then applied to the actual ship. However, the design and production of ship model will directly affect the results of the study. In this paper, firstly analysis the similarity theory from the perspective of cathode protection, then propose the considerations when designing a ship model according to the analysis results and finally gives a electric field distribution characteristics when a finished ship models doing cathode protection. From the results, this paper consider the cathode protection, proposed the design factors for producing a good performance scale ship model.
