Abstract:

In order to acquire the anti-seismic capability of ITER external bypass, response spectrum method has been carried out to study the seismic performance through finite element software ANSYS Workbench. Maximum equivalent stress, directional deformation and reaction force of fixed supports of the external bypass structure are analyzed under the design seismic spectrum provided by ITER organization. The analysis results show that the maximum equivalent stress is not more than 8.3MPa, and the maximum directional deformation is not more than 2.6mm. The results above indicate that the external bypass structure can meet anti-seismic requirements. In addition, the results also provide reference for the foundation design of the external bypass, as well as make a contribution to the follow-up seismic design work.
