CICC导体数值模拟设计的发展

Development of the simulation for CICC design

管内电缆导体(Cable-in-Conduit Conductor,简称CICC)是大型低温超导磁体的首选导体,在大电流和快速变化磁场环境中,CICC导体能否稳定运行受多种因素影响,因而对CICC导体的稳定性以及导体的设计进行数值模拟,来简化工程上CICC导体设计研究的复杂烦琐过程,缩短工作周期。目前,国内外关于CICC数值模拟的程序,由于侧重于解决不同的问题,各有利弊。基于此,文中在系统阐述CICC数值模拟领域内的相关情况后,对它们进行了全新的总结和论述,并给出了导体数值模拟研究的一些可能发展方向。

CICC has been the first selected conductor for large cryogenic superconducting magnets. Under the condition of high current and rapid changing magnetic field, there are many factors to affect the steady operating for CICC. So, the simulation of design for CICC was put forward to simplify the process to design CICC in engineering, and to shorten cycle of design CIGC. However, today all the programs for design CICC have their advantages and disadvantages because they emphasized particularly on different problems. Based on these simulations, the paper demonstrated them from different view. After the systematical analyses of the papers in different phases, several promising directions for future researches are also proposed in this paper.
