【Abstract】 On the basis of the commercial finite element software ANSYS and the Bean critical state model,this paper simulated and analyzed the magnetic field and levitation force of a new-style high temperature superconducting(HTS) hybrid magnetic bearing system which is composed of a cylindrical superconductor,a permanent magnet and a superconducting coil.The effect which influenced the value of the levitation force in HTS hybrid magnetic bearings was researched,and the levitation force was also measured in experiments.The result shows that the simulation is nearly consistent with the experiment,and it is convenient and feasible to use the software for simulation.The result is relatively exact and reliable which will be an effective reference for design and optimization of HTS hybrid magnetic bearings.更多还原
