摘　　要：[目的]为实现船舶快速和高质量退磁,提出一种环形线圈退磁设施的新技术方法。[方法]首先,研究环形线圈退磁设施的电磁设计,确定其基本结构,完成理论分析、模拟仿真和电磁计算;然后,分别在南北航向和东西航向构建环形退磁线圈退磁设施的缩比物理模型,依次对两型水面船舶模型和两型水下船舶模型进行退磁试验;最后,对环形工作线圈退磁设施的实船退磁可行性进行分析。[结果]理论分析和船模试验结果表明,环形工作线圈退磁设施在东西航向的退磁效果比在南北航向的退磁更具优势,退磁电流容易调节,退磁效果好,速度非常快,且具有建设费用低的优点,[结论]特别适用于水下船舶退磁工作。[Objectives]In order to achieve the fast and high quality demagnetization of ships,a new demagnetization technique adopting a ring-shaped working coil is proposed.[Methods]First,the electromagnetic design of the demagnetization facility with a ring-shaped working coil is studied comprehensively,including the main framework,theoretical analysis,simulation and calculation of electromagnetic data.Next,in the north-south direction and east-west direction,a model of the demagnetization facility with a ring-shaped working coil is constructed and demagnetization tests carried out on models of two types of surface ship and two types of underwater ship.Finally,the feasibility of the demagnetization facility with a ring-shaped working coil is analyzed.[Results]The theoretical analysis and ship model test results show that the demagnetization facility with a ring-shaped working coil has advantages in the east-west direction because of the easily adjusted demagnetization currents,good demagnetization results,very fast demagnetization speed and low construction cost advantage.[Conclusions]The results of this paper show that this proposal is especially suitable for the demagnetization of underwater ships.
