| 摘 要： | 由于原参考设计的ITER纵场磁体重力支撑座的真空电子束焊接难度，对支撑座进行了两种方案的更改设计。将支撑座部件从中间剖分成相等两半的“一分为二电子束焊接方案”设计以及取消焊接工艺的“螺栓夹紧方案”设计。用解析法和有限元法对这两种设计进行了屈曲分析，它们都有足够的安全裕度，表明这两种方案都可行。通过对这两种方案的比较，由于“螺栓夹紧方案”制造简单、废品率低、极大地降低制造费用、生产周期缩短，建议采用“螺栓夹紧方案”。

| Abstract: | According to the original reference design, the gravity support pedestal (GSP) of ITER toridal field magnet will be very difficult to fabricate because of large vacuum electronic welding, and therefore, two conceptual alternative designs, "split vacuum electronic welding option" and "bolt clamping option", are put forward. The preliminary buckling analyses with FEM (finite element method) and hand calculation show that there are enough safety margin in two options and both of them are feasible. Even though ... |
