Problems solved by technology

At present, the relevant devices and field cooling technology are mainly based on small-scale, basic experimental research in the non-free suspension state. In the application of high-temperature superconducting maglev trains, there is a lack of automatic control systems dedicated to field cooling of high-temperature superconducting maglev trains. The technical solution adopts standard parts support or non-synchronous lifting mechanism to manually locate and lift the spatial position of the suspended Dewar, which has a large position control error. At the same time, it is difficult to ensure the cooling of the synchronous lifting field under the distributed placement of the suspended Dewar

Abstract

The invention discloses a synchronous landing system and a cooling method for a high-temperature superconducting maglev train. The synchronous landing system comprises a synchronous landing unit and an auxiliary support mechanism. In the field cooling process of high-temperature superconducting maglev trains, this application can realize synchronous field cooling of multiple suspended Dewars, effectively improve the positioning accuracy between the suspended Dewars and the permanent magnet track, and suppress vertical and lateral positioning errors and non-synchronization The unbalanced load-carrying performance distribution, suspension force attenuation, lateral drift and rollover caused by field cooling have improved the distribution, suspension guidance performance, stability, reliability and safety of high-temperature superconducting maglev trains with large loads. It has important application value in the fields of electromagnetic launch and maglev transportation.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a synchronous take-off and landing system and a field cooling method for a high-temperature superconducting maglev train. Background technique [0002] In the development of social civilization, human beings have never stopped pursuing speed. The maximum commercial running speed of high-speed trains has reached 350 km / h. Further speed increases will be limited by the adhesion of wheels and rails. Maglev trains use magnetic force to achieve non-contact. support and guide, so as to obtain higher running speed. Japan's low-temperature superconducting magnetic levitation train has achieved a maximum test speed of 603 km / h, and the "Hyper High 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 1000 km per hour. The test vehicle was rolled off in Qingdao. In addition, the high-temperature super...
