Abstract In order to improve the efficiency and stability of large-scale flywheel energy storage systems, a thrust bearing which consisted of 16 superconducting shoes and 8 small orifice restrictors that were composed of static pressure tiles was designed, combined with superconducting magnetic force and hydrostatic fluid force. Firstly, an analysis model was established based on superconductor local model and hydrostatic fluid equation. And then, performance indexes such as stiffness of the composite bearings were analyzed by decoupling method, and the composite bearings were optimized. The results show that the composite bearings may ensure stable suspension and maintain high rigidity, and the power loss is within the acceptable ranges.

Key words： flywheel energy storage superconducting magnetic force thrust bearing hydrostatic fluid force performance analysis stiffness
