Abstract

In order to accumulate experience in the design and manufacturing of the toroidal field coils for the China Fusion Engineering Test Reactor, a model coil of mixed Nb3Sn-NbTi superconducting magnet with a maximum magnetic field variation rate of 1.5 T/s has been developed at the Institute of Plasma Physics, Chinese Academy of Sciences. The preload system, as one of the key components of the model coil, plays a crucial role in maintaining the overall integrity and stability of the model coil. First the magnetic field and electromagnetic forces of the model coil under extreme conditions are calculated based on Maxwell's equations. Then, the mechanical performance of the model coil at room and cryogenic temperatures is analyzed. To addressing the issue of excessive stress in the preload components of the model coil under preload, several optimization design schemes are proposed and iteratively analyzed. Finally, stress linearization is performed, and stress evaluation is conducted based on the analytical design. The assessment results indicate that certain optimization schemes enable the preload components to fully meet the operational requirements at both room and cryogenic temperatures. The outcomes presented in the paper will provide reference for the subsequent design and manufacturing of the central solenoid coil.

多工况下CSMC预紧系统的力学分析及结构优化
为了积累中国聚变工程试验堆环形场线圈的设计和制造经验,中国科学院等离子体物理研究所研制了一种最大磁场变化率为1.5 T/s的Nb3Sn-NbTi混合超导磁体模型线圈。预紧系统作为模型线圈的关键部件之一,对保持模型线圈的整体完整性和稳定性起着至关重要的作用。首先根据麦克斯韦方程组计算了模型线圈在极端条件下的磁场和电磁力。然后,分析了模型线圈在室温和低温下的力学性能。针对模型线圈在预紧作用下预紧构件应力过大的问题,提出了几种优化设计方案并进行了迭代分析。最后进行应力线性化,并根据解析de符号进行应力评估。评估结果表明,某些优化方案可以使预载部件完全满足室温和低温下的运行要求。本文提供的研究成果将为后续中央电磁线圈的设计和制造提供参考。
