1. 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.
