Static Structural Analysis of 3D Loading Frame for ITER Gravity Support Prototype

The importance of static structural analysis for the 3D loading frame of the ITER gravity support prototype was described. The finite element model was established based on ANSYS Workbench. The forces applied on the 3D loading frame were analyzed. The static structural analyses of 3D loading frames under different working conditions were done with finite element method. Deformations, overall mean stresses and safety factors were then solved. Results show that the maximum total deformation, the y-direction maximum deformation, the maximum stress and the minimum safety factor for different working conditions meet the design requirements. The stress concentration region and the weakest part in the 3D loading frame were analyzed. The corresponding improved measures were presented.
