Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a high-temperature superconducting maglev train synchronous landing system and a field cooling method. Background technique [0002] In the course of the development of social civilization, human beings have never stopped pursuing speed. The maximum commercial operating speed of high-speed trains has reached 350 km / h. Further speed increase will be limited by the adhesion force of wheels and rails. Maglev trains use magnetic force to achieve contactless Support and guide, so as to obtain higher operating speed. Japan's low-temperature superconducting electric maglev train has achieved the highest test speed of 603 km / h, and the "hyperhigh-speed rail" in the United States has realized the manned test in a low-pressure pipeline for the first time, and its theoretical speed can reach 1,000 km per hour. The test prototype vehicle rolled off the production line in Qingdao. In addition, t...
