Problems solved by technology

However, the manufacturing process of this high-temperature superconducting maglev experimental vehicle is complex, costly, and huge in size, so it cannot be popularized in general university laboratories and exhibition halls, so many people cannot see the demonstration of the train running with their own eyes.
At present, the existing small high-temperature superconducting maglev experimental vehicle model can only give people a perceptual understanding, which is far from satisfying the detailed understanding of the system by teachers and students in universities and key middle schools. Therefore, it is very necessary to have a set of high-tech vehicles. A multi-functional device for teachers, students and the general public to understand various technologies related to the superconducting maglev train system

Description

technical field [0001] The invention belongs to the technical field of magnetic field and magnetic demonstration devices, and in particular relates to a high-temperature superconducting maglev train experiment and demonstration device. Background technique [0002] Traditional railway trains rely on various types of locomotives such as steam, fuel oil, and electric power as traction power, and the interaction between wheels and rails serves as running guidance. The railway line bears pressure and rolls along the rails with the help of wheels. The maglev train relies on the unique characteristics of "same-sex repel and opposite-sex attract" to hold up the vehicle, so that the entire train is suspended on the track, guided by electromagnetic force, and directly converted into electrical energy by using a linear motor. A means of transportation that propels the train forward. The prominent advantages of maglev trains are fast speed, light noise pollution, low energy consumptio...
