Maglev train is a kind of train driven by magnetic levitation force, which realizes non-contact suspension and guidance between the train and the track through electromagnetic force, and then the train is towed by electromagnetic force generated by linear motor.
Because of the magnetic force of its orbit, it is suspended in the air, which reduces the friction. Unlike other trains, they need to touch the ground when walking, and are only resisted by the air. The speed of high-speed maglev trains can reach more than 400 kilometers per hour, and most of the medium and low-speed maglev trains are the fastest ground vehicles with a speed of 100 to 200 kilometers per hour.
The history of maglev train;
1922, German engineer Herman Qiang 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.
On June 5438+ 10, 2003, the first maglev train in China (purchased from German) started running on the Shanghai maglev line. 20 15 10 Changsha maglev line, the first domestic maglev line in China, was successfully put into trial operation. 2065438+June 2008, the first commercial maglev version 2.0 train in China rolled off the assembly line at CRRC Zhuji Electric Locomotive Co., Ltd.
202 1, 65438+February, 14, Xingguo, the first maglev empty rail vehicle in China, rolled off the assembly line in Wuhan.
