摘要
在脉冲强磁体设计中 ,磁应力是目前面临的最大困难 ,当磁场强度达到 10 0T时 ,磁体绕组中的磁应力高达 4GPa,这是目前任何实用导体材料都无法承受的 ,因此 ,脉冲强磁体的发展在很大程度上取决于磁应力的解决情况 .文章介绍了国外在解决脉冲强磁体巨大应力问题上采用的方法 ,主要叙述了新材料技术、绕组加固技术和改善电流分布技术 。
The most serious problem in magnet design is the strong magnetic stress.In 100T magnets the stress is 4GPa,which exceeds the strength of the strongest conductor materials now available,so the development of pulsed magnet depends to a great extent on the solution of this problem.We describe various methods used abroad to solve this issue,including new materials development,coil reinforcement and improved current distribution technology.Finally,the merits,shortcomings and performance of the new methods are presented.
