Is maglev a new type of transportation?

Maglev train is a new type of vehicle consisting of train, contactless magnetic bearing, magnetic guidance and linear drive system. Maglev train is a modern high-tech rail transit vehicle, which realizes non-contact suspension and guidance between the train and the track through electromagnetic force, and then draws the train by electromagnetic force generated by linear motor. 1922, German engineer HermannKemper put forward the principle of electromagnetic levitation, and then applied for a patent. Since 1970s, with the strengthening of the economic strength of industrialized countries, Germany, Japan, the United States and other countries have successively carried out research and development of magnetic levitation transportation systems to improve their transportation capacity and meet the needs of their own economic development and people's lives. Among them, Germany and Japan have made great achievements. China's first maglev train (purchased from German) started operation in Shanghai in June 2003. 20 15- 10 Changsha maglev line, the first domestic maglev line in China, was successfully put into trial operation. 2065438+May 23, 2009 10: 50, China 600 km/h high-speed maglev test prototype rolled off the assembly line in Qingdao.
