Abstract

For the enclosure welding of the correction coil cases of CFETR, a electron beam welding equipment will be set up. The welding vacuum vessel is the requisite vacuum container for electron beam welding equipment. In the paper a large vessel is designed according to box-shaped shell theory. The preliminary structure parameters are achieved through the theory calculation. To improve the transport-ability, manufacture-ability and assembly-ability, the large vacuum vessel is divided into three segments. In course of structure design and analysis of the vessel, the 3D model of the phased vacuum vessel is established. And the weakest part of the vessel is chosen as analysis and optimized object. Through structure parameters optimizing and analysis simulation, the final required dimensions of the phased vacuum vessel is acquired, which sets up the solid basis for the successfully building of the electron beam welding equipment.
