How do foreign countries study maglev trains?

The theoretical preparation time of maglev train has a long history. In fact, magnetic levitation technology originated in Germany. According to records, as early as 1922, German engineer Herman Qiangsuo put forward the principle of electromagnetic levitation, and applied for the patent of maglev train in 1934. However, after the 1970s, the economic strength of the world's industrialized countries has been continuously strengthened, and it has become more and more obvious to improve the transportation capacity accordingly to meet the needs of their economic development. Since then, Germany, Japan, the United States, Canada, France, Britain and many other developed countries have begun to plan to develop maglev transportation systems. So far, Germany and Japan have made remarkable progress in the research of magnetic levitation system.

Maglev railway with constant conductance was studied in 1962, and superconducting maglev railway was studied in the early 1970s. 1972, the experiment of superconducting maglev train with a speed of 50 kilometers per hour was successful for the first time. 1977, the top speed reached 204 kilometers per hour in February, and increased to 5 17 kilometers in February. Until June 1982, 1 1, the manned test of maglev train was successful. 1995, the maximum speed of manned maglev train reached 4 1 1 km during the test. The first phase of Japan 18.4 km long test line was completed as early as 1996.

1968 maglev railway research in Germany. At the beginning of the research, constant conductance and superconductivity were both important. 1977 successively developed the test vehicle with the attraction of the permanent magnet and the repulsion of the superconducting electromagnet, and the maximum speed during the test can only reach 40 kilometers per hour. Later, I decided to concentrate on developing maglev railway. The test line with a total length of 3 1.5km was built in Emsland, 198l was completed, and 1982 started the unmanned test. By 1983, the speed reached 300 kilometers per hour, 1984, and the speed reached 400 kilometers per hour.

Britain began to study maglev railway from 1973, but Britain was one of the first countries to put maglev railway into commercial operation. In April, 1984, a 600-meter-long maglev railway between Birmingham Airport and Intertenar Station was officially opened to traffic. ]
