摘要: 针对强磁场托卡马克环向场(TF)线圈应力过大、结构材料难以承受的问题,根据静水应力原理分析了通过外部承压结构来降低TF线圈内腿应力的有效性。采用COMSOL有限元软件开展模拟,研究了液氮冷却强磁场铜导体托卡马克外部承压结构在不同厚度下TF线圈磁体应力的降低程度;对比了铍铜合金和无氧铜作为导体材料所需要的外部承压结构的厚度和体积。

关键词: 托卡马克, 强磁场, 环向场线圈, 应力缓解

Abstract: In response to the problem that a high magnetic field tokamak toroidal (TF) coils are too excessive stress to be sustained by the structural and conductor materials, according to the principle for forming hydrostatic stress, the effectiveness for reducing the stress of inner leg of TF coils of a high magnetic field tokamak has been carried out. The stress reduction of TF coil magnet with external supporting structure in a liquid nitrogen cooled high magnetic field copper conducting tokamak was studied by using COMSOL finite element software. The thickness and volume of external supporting structure required were compared for beryllium copper alloy and oxygen free copper as conductor materials.

Key words: Tokamak, High magnetic field, Toroidal field coils, Stress mitigation
