边界局域模线圈是国际热核聚变实验堆中用来抑制边界局域模现象的核心部件,在正常运行情况下,线圈中的电流和外部的背景场相互作用,在线圈上产生巨大的磁场和电磁力。由于边界局域模线圈通过螺栓连接固定在真空室内壁,在电磁载荷的冲击下会在线圈的铠甲和支撑部件上产生较大的剪切应力,一旦Tresca 应力超出材料的设计应力强度阈值,线圈的设计寿命和可靠运行将受到严重影响。文章根据麦克斯韦方程计算线圈上的磁场大小和电磁力分布,并将电磁力作为外部边界条件,借助有限元分析工具ANSYS提取线圈上的剪切应力,基于ASM E标准,采用分析设计的方法对应力进行分类评定,验证了设计方案的可行性。
邊界跼域模線圈是國際熱覈聚變實驗堆中用來抑製邊界跼域模現象的覈心部件,在正常運行情況下,線圈中的電流和外部的揹景場相互作用,在線圈上產生巨大的磁場和電磁力。由于邊界跼域模線圈通過螺栓連接固定在真空室內壁,在電磁載荷的遲擊下會在線圈的鎧甲和支撐部件上產生較大的剪切應力,一旦Tresca 應力超齣材料的設計應力彊度閾值,線圈的設計壽命和可靠運行將受到嚴重影響。文章根據麥剋斯韋方程計算線圈上的磁場大小和電磁力分佈,併將電磁力作為外部邊界條件,藉助有限元分析工具ANSYS提取線圈上的剪切應力,基于ASM E標準,採用分析設計的方法對應力進行分類評定,驗證瞭設計方案的可行性。

The edge localized mode(ELM) coil is the key component of the International Thermonuclear Experimental Reactor(ITER) .The main function of the coil is to suppress the phenomenon of ELM . During the normal operation ,giant electromagnetic force will be generated by the interaction of the current in the coil and the external background field .Since the coil is connected to the in-vessel wall , high Tresca stress will be caused on the supporters and jackets under the electromagnetic load .Once the Tresca stress is beyond the threshold ,the coil will be in danger .In this paper ,according to Max-well equations ,the magnetic density and Lorentz force were calculated .The electromanetic load was applied on the finite element model and the Tresca stress was extracted by the use of the software AN-SYS .Based on ASME standards ,the stress was evaluated by using the method of analytical design . The result verified the feasibility of the current design plan .
