Design of Hybrid Suspension System of Superconducting and Electrostatic Suspension

A new structure of superconducting suspension system is proposed based on a method used to calculate the magnetic field in a thin clearance between superconducting blocks. Force characteristic of the passive superconducting suspension system is analysed. Based on the existing structure of superconducting suspension system, an electrostatic suspension system is introduced to obtain high suspension stiffness. Details of the hybrid suspension system are introduced and the corresponding controller is also described. This paper provides a theoretical guidance for the next experiment, and also has reference to designing high stiffness suspension system.
