英文摘要	The design of a 14 T MRI system was recently announced by the Institute of the Plasma Physics Chinese Academy of Sciences. This system is operating at 4.5 K and 1848 A to produce a magnetic field of 14 T. Because of the high magnetic field and high working current of the system, the 14 T MRI magnet is subjected to huge electromagnetic load and mechanical load during the operational period. The preload structure of MRI is used to overcome the coil gravity and eliminate the relative gap between the coils. In this paper, the preliminary structure design of 14 T MRI system is introduced, and the mechanical properties of preload structure and support structure are evaluated. Through the finite element analysis, the preload structure meets the material strength, and the design is reasonable.
