ITERELM线圈支撑的结构分析与优化设计

Structural analysis and optimization of the middle ELM coil support for ITER

ITER ELM线圈的安装位置和工作环境使其在运行中会承受很大的电磁力和受到因核热和欧姆热产生的热膨胀。使用ANSYS有限元软件对六种不同支撑结构做了应力分析,并进行了优化设计。最终确定了当横向梳齿上下两端的通孔为椭圆形且是V字形排列时其最大Tresca应力最小。分析结果为支撑的合理设计提供了理论依据。

Due to the position of ITER ELM coils assembly and its working condition, these coils are subjected to large electromagnetic force and thermal expansion caused by the nuclear heat and ohmic heat. The stress analysis and optimization work within six different design schemes of ELM Coils （ELMC） support are carried out by finite element software ANSYS. The analysis results proof that when the support has the V character configuration alignment of its transversal elliptical through-holes on both ends of top and bottom, the maximum Tresca stress is at the lowest value. The final outcome brings about meaningful reference for ELMC support design.
