【Abstract】 The super conducting Toroidal Field (TF) coil system of HT 7U is a very important part of HT 7U superconducting tokamak device, which has rather complex structures. In order to design the mechanical structure of TF system, it is very necessary to analyze the mechanical characteristics at the working temperature (Liquid Helium temperature). But the structure of this device is very difficult to experiment on directly because of its complex structures. In this paper, the stress distribution of cross section of TF straight area under electromegnetic force is analyzed by using finite element method. The influence of fillet radius of cable jacket on stress distribution is also analyzed. And some results are given, which will help to analyses the mechanical behavior of HT 7U tokamak device.更多还原
