摘要
针对ITER重力支撑系统的特点,提出了ITER重力支撑系统的有限元静力分析方法。应用ANSYS软件,建立了ITER重力支撑系统三维实体模型。采用精度比较高,且计算规模又可以接受的单元网格划分方法,进行网格划分。在Volume之间的界面上定义接触单元。得到了支撑系统有限元模型。对受静负载作用的ITER重力支撑系统进行了有限元静力分析。获得了支撑系统各零件的应力分布及最大应力,分析了这些零件的强度。静力分析的结果为ITER重力支撑系统的设计或改进提供了可靠的理论依据。
A finite element static analysis method of the gravity support system for the ITER was proposed according to the characteristics of the gravity support system. The three dimensional model of overall gravity support system was built by using ANSYS. A mesh dividing method, which possesses high precision and an acceptable calculating scale, was used. The contact elements were defined on interfaces between volumes.The finite element model of the gravity support system was built. The finite element static analysis of the gravity support system under the Dead Weight was performed. The stress distribution and the maximal stress values of all parts of the gravity support system were obtained, and the stress intensity of parts of the gravity support system was analyzed. The results of static analysis lay the solid foundation of the design and improvement of the gravity supports system of ITER.
