Wang Zugang completed the full-scale superconducting electric suspension test on behalf of the domestic high-speed flying car
Science and Technology ** Beijing, March 4 (Reporter Jiaoyang) China's first maglev test line with completely independent intellectual property rights - high-speed flying car Datong (Yanggao) test line has recently successfully completed the full-scale superconducting electric suspension test. On the 4th, Wang Zugang, deputy manager of the Shijiazhuang Project Department of Fengqiao Company of China Railway Sixth Bureau, revealed the news to the science and technology reporter.
High-speed flying car refers to the ultra-high-speed low-vacuum pipeline maglev transportation system, which has the characteristics of faster, more convenient, more comfortable, safer and more economical and controllable. When the train is running in a closed environment with a special vacuum pipe line, the superconducting maglev technology will help the train to disengage from the ground, greatly reducing friction and air resistance, so as to achieve a speed of more than 1,000 kilometers and hours of "near-earth flight".
According to Wang Zugang, the full-scale superconducting electric suspension test completed by the Datong test line verified the key technologies such as the coupling dynamic analysis and control of the "vehicle-pipe-line" complex system, the stable suspension of the large-mass supernavigation vehicle, the high-power traction transmission, and the safety collaborative control of the whole process, refreshed the maximum sailing speed of the domestic full-scale superconducting electric suspension, improved the overall technical maturity of the system, and laid a solid technical foundation for the follow-up higher speed test of the high-speed flying car. The next step will be to carry out vacuum pumping and vacuum state sports car tests in an orderly manner.
The Datong test line is located in Yanggao County, Datong City, Shanxi Province, with a total length of 2 kilometers in the first phase of the project, of which the vacuum pipeline is the main project of the test line, which is connected by several single pipelines. The diameter of each single-section pipe beam is 61 meter, 30 meters long, during construction, the overall geometric size error must be less than 2 mm, to ensure that the inside of the pipe beam reaches a long-term vacuum state during operation.
