摘要
Abstract
Stiffness characteristics reflect the stability of superconducting magnetic bearing,which is one of the main evaluation indexes of the overall performance of high temperature superconducting magnetic bearing.In order to explore the radial bearing structure with better stiffness characteristics,the author simulated and designed three different types of radial bearings through COMSOL software,compared and analyzed the electromagnetic characteristics of radial bearings with different structures,and then analyzed the force and stiffness characteristics.The results show that the magnetic flux density around the radial bearing of the permanent magnet with larger thickness and uniform structure is larger,the magnetic field gradient is stronger,and the stiffness characteristics are better.The radial bearing of this structure can be used in the subsequent design.关键词
