对圆芯导体（CORC）电缆的磁化特性进行了数值研究。本文介绍的数值模型是基于有限元法（FEM）的简化结构，优化的假设和设置。CORC电缆的磁化特性可以用完全耦合模型和孤立模型来描述。这些数值模型进行了验证的CORC电缆的商业HTS磁带的实验。在此基础上，本文讨论了CORC电缆中超导层的磁屏蔽效应和CORC短电缆中磁化损耗的端部效应。所得结论有助于理解CORC索的工作机理，对基于CORC索的大型磁体的设计具有指导意义。
This paper presents numerical study on magnetization characteristics of conductor on round core (CORC) cable. Numerical models introduced in this paper are based on finite-element method (FEM) with simplified structure, optimized assumptions and settings. Magnetization performance of CORC cables is represented by both full coupled model and isolated model. These numerical models are verified by experiments on CORC cables made of commercial HTS tapes. On basis of this, two topics are discussed in this paper: one is the magnetic shielding effect of superconducting layers in CORC cables; the other one is the end effect of magnetization loss in short CORC cables. Conclusions obtained in this paper will be helpful to understand the working mechanism of CORC cable and also useful in design of large-scale magnets based on CORC cables.
