1. A testing platform for evacuated tube high-temperature superconducting magnetic levitation (HTS maglev), comprising:
an evacuated tube;
a supporting platform assembly;
a model train; and
a gantry;
wherein one end of the evacuated tube is closed, and the other end of the evacuated tube is provided with an isolation door;
the supporting platform assembly is arranged in the evacuated tube; a permanent magnet track and a stator winding are arranged on the supporting platform assembly; and the permanent magnet track is configured for researches of dynamic characteristics of a train passing another train running in opposite direction;
a mover and a cryogenic dewar are arranged at a bottom of the model train; a plurality of superconducting bulks are provided in the cryogenic dewar; the stator winding and the mover are configured to be energized and coupled to generate a driving force to propel the model train forward; the plurality of superconducting bulks are configured to cooperate with the permanent magnet track to generate a levitation force; and a side wall of the model train is made of a metal material;
the gantry is arranged on the supporting platform assembly; a permanent magnet is arranged on an upright post of the gantry; and the permanent magnet is configured to be coupled with the model train to form an eddy current on a body of the model train; and
the number of the stator winding is two, and the mover is arranged between two stator windings.
