摘要： A dynamic simulation test platform for ultra-high-speed evacuated tube magnetic levitation (maglev) transportation includes an evacuated tube having a transition section and a vacuum section, a vacuum maintaining system, a motor supporting platform, and a model train. One end of the evacuated tube is provided with a first isolation door, and the other end is closed. A second isolation door is provided inside the evacuated tube. The vacuum maintaining system is connected to the transition section and the vacuum section. The motor supporting platform is provided in the evacuated tube and extends outside the transition section. The motor supporting platform is provided with a stator winding and a permanent-magnet track. A mover and a cryogenic dewar are provided at a bottom of the model train. The cryogenic dewar is provided with a superconducting bulk. A test method using the test platform is further provided.

摘要： A testing platform for evacuated tube high-temperature superconducting magnetic levitation (HTS maglev) under a high-speed operation state, including an evacuated tube, a supporting platform assembly, a model train and a gantry. The supporting platform assembly is arranged in the evacuated tube, and is provided with a permanent magnet track and a stator winding. A mover and a cryogenic dewar are arranged at a bottom of the model train, and multiple superconducting bulks are arranged in the cryogenic dewar. A side wall of the model train is made of a metal material. The gantry is arranged on the supporting platform assembly, and permanent magnets are arranged on upright posts of the gantry. A testing method using the testing platform is also provided.
