On January 25th, at the expert review meeting of the 600 km / h high-speed maglev transportation system technical plan, the technical plan for the 600 km / h high-speed maglev transportation system passed the expert review, which marked the country led by CRRC Sifang Co., Ltd. The key research and development project "Key Technologies of High-Speed Maglev Transportation System" has achieved important initial results. It is estimated that a high-speed maglev vehicle with a speed of 600 kilometers per hour will be developed in 2020, and the 5km test line verification will be completed, which will fill the gap of domestic high-speed maglev trains.
The high-speed maglev transportation system is composed of maglev vehicles, ground traction control, operation control, line track systems, etc., involving many disciplines and specialties, and is a highly technically difficult system project.
As a new cutting-edge rail transit technology, the advantages of high-speed maglev have been paid more and more attention to by many countries. Developed countries such as Germany and Japan have developed a variety of maglev transportation schemes along different technical routes. Japan ’s superconducting maglev technology has achieved a test speed of 603km / h, Germany ’s maglev technology has a maximum test speed of 505km / h, and the world ’s first commercial high-speed maglev line operating at a speed of 430km was built in Shanghai, China, but at a speed of 600 Kilometers of high-speed magnetic levitation system and its engineering application are still blank in China.
At present, the highest operating speed of the high-speed rail is 350 km / h, the economic speed of aviation cruise is 800 ~ 1000 km / h, and the high-speed maglev transportation system with a speed of 600 km per hour can fill the speed gap between high-speed rail and air transportation. High-speed magnetic levitation can be used for long-distance transportation and fast commuting. It is especially suitable for three modes of transportation, namely, "commuting" transportation with large economic scale, high synchronization, and strong integration. The economic scale is large and complementary. "Similar urbanization" transportation between large cities with high demand for coordination and the large-scale development of the "corridorized" transportation between the eastern and western central cities with large differences in economic scale and balanced development needs.
According to reports, the high-speed maglev transportation system technical plan passed the review, which means that the next step can enter the construction design, which has important node significance. According to the project plan, a prototype will be developed in 2018, and a high-speed maglev vehicle with a speed of 600 kilometers per hour will be developed in 2020. The 5km test line will be verified and integrated demonstrations will be conducted to lay the foundation for the application and industrialization of high-speed maglev engineering.
