摘要
Finite Element Method is used in this article to analyze the stress of CR superferric magnet.Magnetic force and the stress caused by this force are calculated.The thermal stress and strain of the coil caused by cooling down is also analyzed.The result will be taken as a check for the design of the coil and coilcase,and also as a reference for the optimization of further design and quench protection.
采用有限元分析的方法,以CR超导二极铁为研究对象,对其进行受力分析,分别计算线圈所受到的电磁力以及在此力作用下线圈发生的应变,线圈和相邻部分降温速率不均匀引起的热应力的分布以及线圈发生的应变.最后利用所得到的数据来校对线圈和线圈盒的强度,为结构的优化设计提供依据,并为失超保护提供可参考的数据.
