Coupled Finite Element Thermal-Mechanical Analysis of Gravity Support System of International Thermonuclear Experimental Reactor

  • A method for building the finite element model of the gravity support system of the international thermonuclear experimental reactor (ITER) was put forward according to the structure characteristics of the gravity support system.By this method,a 3D finite element model of the gravity support system was built with ANSYS software using a mesh generation method of high precision and with an acceptable calculation scale.Then,a coupled thermal-mechanical analysis of the gravity support system was carried out,and the maximum Tresca stress and its position in every part of the system were obtained under the combined action of dead weight,thermal load,electromagnetic forces and seismic load.The stress analysis results show that the maximum stresses in all parts of the system are smaller than their respective allowable stress limits,and that the parts have enough mechanical strength to meet the requirements of ASME Pressure Vessel Code-III NF.
