The Institute of Plasma Physics Chinese Academy of Sciences (ASIPP) has announced a project to design a 14 T MRI magnet with a 900 mm warm bore and comprised of Nb3Sn Rutherford cables, the homogeneity of the magnetic field is better than 0.5 ppm in a 22 cm diameter spherical volume. The diameter of main coil is about 4 m and the total weight is about to 130 tons. This article describes structural design of 14 T MRI suspension system. A global finite element model is created based on the design geometry data to investigate the mechanical property of the suspension system under the seismic load.
