Abstract: Vacuum vessel is the location for the operation of plasma
as one of the key component for HT-7U superconducting Tokamak device.
During it operation the vacuum vessel will endure not only the
electromagnetic force but also the pressure of boride water and the
thermal stress owing to the 250 °C baking out. Firstly the
electromagnetic force under the plasma disruption and vertical
displacement event is analyzed using the numerical analysis method. And
secondly the stress distribution and displacement for the vacuum vessel
is analyzed employing COSMOS and NASTRAN finite element software. Some
valuable theory basis and analysis method can be provided for the vacuum
vessel of the semblable superconducting tokamak device.
Key words: Tokamak Vacuum vessel Numerical analysis
