Title:
HIGH-TEMPERATURE SUPERCONDUCTING MAGNETIC SUSPENSION DEWAR FOR INCREASING DAMPING AND SUSPENSION FORCE, AND WIDTH CALCULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/246453
Kind Code:
A1
Abstract:
The present invention provides a high-temperature superconducting magnetic suspension dewar for increasing damping and a suspension force, and a width calculation method, which relate to the technical field of high-temperature superconducting pinning magnetic suspension. The dewar comprises an outer box body, wherein an inner box body is fixedly connected inside the outer box body by means of a connection column, the inner box body is of a cavity structure, a cavity of the inner box body is used for containing liquid nitrogen, a superconducting bulk material is arranged at the bottom of the cavity of the inner box body, the inner box body is in communication with the outside through a liquid nitrogen filling pipe, and the outer box body is made of a conductive material. In the present application, by means of the outer box body of the magnetic suspension dewar, which is closest to a permanent magnet track, has a larger magnetic field gradient at a position where the dewar is positioned and has the largest opposite area with the permanent magnet track as an apparatus for increasing system damping, compared with stainless steel materials in the prior art, damping of the magnetic suspension dewar can be significantly increased, and a vibration attenuation capacity of the magnetic suspension dewar can be improved.
