High-temperature superconducting (HTS) magnetic levitation (maglev) Dewar capable of increasing damping and levitation force and width calculating method thereof

A method for calculating a width of a high-temperature superconducting (HTS) magnetic levitation (maglev) Dewar capable of increasing damping and levitation force, comprising:

• (a) acquiring parameter information of a permanent magnet rail;
• (b) performing static magnetic field distribution calculation according to the parameter information by using a finite element analysis software to obtain a simulation result;
• (c) acquiring, according to the simulation result, a magnetic field distribution state of the permanent magnet rail on a cross section of the permanent magnet rail;
• and
• (d) calculating a width of an outer container of the HTS maglev Dewar according to the magnetic field distribution state and a preset magnetic field gradient range;
• wherein the HTS maglev Dewar comprises the outer container and an inner container;
• the inner container is provided inside the outer container, and is fixedly connected to the outer container through a connecting column;
• the inner container has a cavity configured to accommodate liquid nitrogen;
• a bottom of the inner container is provided with a bulk superconductor;
• the inner container is communicated with outside through a liquid nitrogen feeding pipe;
• and the outer container is made of an electrically conductive material.
