Finite element modal analysis of the gravity support for ITER

Abstract

Abstract:

The 3-D finite element model with 20° sector of the gravity support system is created using ANSYS, and then the modal analysis is carried out with Subspace method. The preceding 10 intrinsic frequencies and vibration patterns of the gravity support system are solved and the trait of vibration patterns is analyzed.

Key words: ITER, Finite element, Gravity support, Modal analysis
