摘要
介绍了ITER的项目背景、稳定性的基本概念以及稳定性分析的基本方法,以ITER杜瓦设备作为研究对象,对其在自重载荷作用下进行了特征值屈曲分析和非线性屈曲分析,得到其失稳模态以及失稳时的临界载荷,为杜瓦的整体设计提供参考。
This article describes ITER project background, the basic concept of stability and the basic stability analysis methods. Taking ITER cryostat as the study object, the article carried out the eigenvalue buckling analysis and nonlinear buckling analysis under self weight, got the instability mode and the instability critical load, which could provide reference for the design of ITER cryostat.
