| 摘 要： | 采用有限元法(FEM)研究了ITER装置中超导校正场底部线圈 (BCC)结构的力学性能。针对BCC结构各组合部件三个方向尺寸的巨大差异，将BCC结构均匀化模型和局部细化模型分步组合，通过有限元分析获得了整体结构和薄弱部位各材料的位移场和应力场。针对BCC结构提出了支撑部位螺栓中预紧力的确定方法，用有限元法得出合理的螺栓预紧力，可用于指导BCC结构的安装。

| Abstract: | The mechanical property of the bottom correction coils(BCC) structure in ITER was analyzed by finite element method (FEM). A strategy by combining the simplified profile BCC structure model and the partly entire profile model was proposed for the considerable difference in the three-dimension size of the component in the BCC structure. The displacement fields and stress fields in the BCC structure and the results of every material in the weak region were obtained by FEM. On the other hand, the method determining the pretightening forces in the bolts of support components was proposed for the BCC structure and the rational pretightening forces of bolts were obtained by FEM. The pretightening forces will be used in installing the BCC structure. |
