摘要:

用ANSYS有限元软件,分析了ITER重力支撑系统的静力情况。采用实体单元建立有限元模型,分析了磁体重量、热载荷、地震和电磁力多种工况下的应力分布及位移变形,获得的最大应力强度和最大位移均在许用应力及允许位移范围内。为进一步优化ITER重力支撑系统提供了重要的参考数据。

Abstract:

The static structural analysis of the ITER (international thermonuclear experimental reactor) overall gravity support is performed by using the ANSYS software of finite element method (FEM); and the stress distribution and displacement under the loads of magnet dead weight, thermal load, seismic load and electromagnetic force are obtained. The maximum stress intensity and maximum displacement of overall gravity support are within the allowable stress limit and displacement limit. This provides an important reference basis to optimize the ITER overall gravity support.

Key words: ITER, Gravity support system, Stress analysis, Flexible, Finite element
