Abstract
The Vacuum Vessel (VV) system is an essential component of Keda Torus for eX- periment (KTX), and various scenarios might take place on it. The VV’s supports should be adequately strong to stand against various loads on VV, which might happen in extreme scenarios. Therefore, the design of VV supports is verified in a single extreme scenario and is subsequently optimized in this report. The numerical simulation based on Finite Element theory is performed as the major method for analysis and optimization. The electromagnetic force in previous analyses serves as the load for the mechanical analyses of supports. During the optimization, the stresses of the VV supports decrease remarkably after introducing cotters. Finally, the optimum design has been worked out. It satisfies the requirements regarding the strength and convenience in assembly.
