China’s 600 Km/h High-Speed Maglev Test Sample Car Successfully Tested
On June 21, a reporter from the Beijing Youth Daily learned from CRRC Sifang Co., Ltd. that the 600-km/h high-speed maglev test prototype developed by it was successfully tested on the maglev test line of Tongji University in Shanghai. This marks an important new breakthrough in my country’s high-speed maglev research and development.
Since the project started in July 2016, after nearly four years of scientific and technological research, the project team broke through the key core technology of the high-speed maglev series and successfully developed a test sample vehicle. After ground debugging and static testing, the vehicle entered the line dynamic operation test. The first test run. For the first time, the test sample vehicle was jointly debugged by the system, and dynamic operation tests were carried out under various working conditions, including different track beams and turnouts, small curves, ramps, zone switching, etc., and completed more than 200 test points in seven major projects. The key performances such as suspension guidance, speed measurement positioning, vehicle-rail coupling, ground traction, and vehicle-ground communication have been fully tested.
According to Ding Sansan, the person in charge of the subject of high-speed maglev and deputy chief engineer of CRRC Sifang Co., Ltd., high-speed maglev is a strong coupling system including four major systems including vehicles, traction power supply, operation control communication, and line and track. It can initially verify the interface relationship and coupling characteristics between high-speed maglev systems under dynamic conditions, providing support for the verification and optimization of key performance of the system and core components.
According to reports, the research and development of the high-speed maglev project is progressing smoothly. At the same time as the successful trial run of the test sample car, the development of five marshalling project sample cars is also steadily advancing. According to the plan, the prototype system of the high-speed maglev project with a speed of 600 kilometers per hour is expected to be rolled out by the end of 2020, and a full set of high-speed maglev technology and engineering capabilities will be formed. In the future, through the construction of a high-speed maglev demonstration project and related operations such as 600km/h line operation, this technology can promote the continuous innovation and industrialization of this technology, and promote the development of my country’s high-end equipment manufacturing upgrades and strategic emerging industries.
As an emerging high-speed transportation mode, high-speed maglev has the advantages of high speed, fast, safe and reliable, strong transportation, comfortable and punctual, green and environmental protection, and low maintenance costs. It has a variety of application scenarios, and can be used for long-distance transportation, that is, “corridor” traffic, forming high-speed corridors between large hub cities or urban agglomerations, promoting inter-regional collaborative development; and suitable for short- and medium-distance passenger transportation, that is, “commuting” “, “Urbanization” transportation, used for commuting in big cities or intercity connection of neighboring cities in urban agglomerations, creating a half-hour to 1-hour economic circle, and promoting the development of “integration” and “co-urbanization” of metropolitan areas and urban agglomerations .
The high-speed maglev of 600 kilometers per hour fills the speed gap between high-speed rail and air transportation, and can form a more reasonable, efficient, flexible and convenient multi-dimensional transportation structure for aviation, high-speed rail, high-speed maglev and urban traffic, to meet the needs of different people.
