我们进行了2米长20 T共线圈偶极磁体的三维（3-D）机械设计，并提供了线圈应力管理的解决方案。代替使用扩口端来为束管腾出空间，原型磁体设计有由四个Nb 3Sn和六个Bi-2212扁平跑道线圈组成的线圈配置。在工作电流为14700 A时，设计的峰值磁场为20.4T.在4.2K时，负载线上的工作裕度为11%. 1/8模型计算得到的水平、垂直和轴向洛仑兹力分别为1562、405和206 t。特殊的线圈配置和如此大的磁力在向线圈施加预载荷以及优化线圈应力和其他部件中的应力方面带来了前所未有的挑战。通过使用扩展的铝壳和分裂轭组件，我们最大限度地减少了线圈端部效应，并向线圈直段和线圈端部施加了均匀且足够大的预载荷。本文介绍了磁体的应力分析和三维机械优化设计。
We carried out the three-dimensional (3-D) mechanical design of a 2-m-long 20 T common-coil dipole magnet and provided solutions for coil stress management. Instead of using flared ends to make space for the beam pipe, the prototype magnet is designed with a coil configuration which consists of four Nb3Sn and six Bi-2212 flat racetrack coils. The designed peak coil field is 20.4 T at the operating current of 14 700 A. The operating margin is 11% on the load line at 4.2 K. The magnitude of the calculated Lorentz force for 1/8 model is around 1562, 405, and 206 t for the horizontal, vertical, and axial directions, respectively. The special coil configuration and such significant magnetic force bring unprecedented challenges in applying preload to coils and optimizing the coil stress and the stress in the other components. By using an extended aluminum shell and a split yoke assembly, we minimized the coil end effects and applied a uniform and large enough preload to the coil straight section and the coil ends. This paper presents the stress analysis and the optimized 3-D mechanical design of the magnet.
