High-speed maglev vacuum pipeline train! Controllable navigation! Stable suspension and safe parking

Rail Transit Exhibition News Recently, China's independent research and development of high-speed maglevVacuum tube trainsThe project successfully completed an important system integration test in Datong, Shanxi Province. This marks another key step in the field of ultra-high-speed ground transportation technology in China.

According to Science and Technology Daily, the test was carried out in a 2-kilometer-long low-vacuum pipeline in Datong. Although the official did not disclose the specific test speed, it said that the test results were in line with expectations. During the test,Superconducting magnetic levitationThe vehicle realizes controlled navigation, stable suspension and safe stop, and its trajectory is highly consistent with the theoretical trajectory.

This test focuses on verifying large-scaleVacuum environment, superconducting navigation and control technology, and system coordination in a low vacuum environment.The person in charge of the project said: "This test has improved the overall technical maturity of the system and laid a solid technical foundation for the next stage of testing. "

The project is jointly developed by the Shanxi Provincial GovernmentChina Aerospace Science and Industry CorporationJointly developed by the company, it aims to achieve a maglev train that "flies" on the ground at a speed comparable to that of an airplane. Full size of the itemTest lineConstruction began in April 2022 and was completed in November 2023, integrating aerospace and railway technologies. Earlier this year, the development team announced that it had broken the previous speed record of 623 km/h.

It is reported that this ultra-high-speed train is expected to connect many large cities in China in the future. For example, it could reduce travel time from Beijing to Shanghai from more than four hours to just 90 minutes by high-speed train.

This innovative technology aims to overcome two major problems faced by conventional rail transport: friction between the wheels and the tracks, and air resistance to the train body. Friction is eliminated through magnetic levitation technology, which uses magnetic push and pull to guide, accelerate and decelerate trains. At the same time, running in a low-vacuum pipe can greatly reduce air resistance and noise.

While there is still a long way to go to realize this future technology, China's continued breakthroughs in this area are encouraging. In contrast, United States entrepreneur Elon · Musk's Hyperloop One company, which once actively promoted similar projects, has closed at the end of 2023.

China's progress in high-speed maglev vacuum pipeline train technology not only demonstrates China's innovation ability in the field of cutting-edge science and technology, but also provides a Chinese solution for the innovation of future transportation modes. With the continuous maturity of technology, we have reason to believe that this "future train" will bring new possibilities for the development of transportation in China and even the world.
