China News Service Qingdao, June 21 (Reporter Yang Bing, Hu Yaojie) CRRC Sifang Co., Ltd. announced on the 21st that the company has undertaken a successful test run of a high-speed maglev test vehicle with a speed of 600 kilometers per hour, which marks the development of China's high-speed maglev research and development. Made important new breakthroughs.
The development of a high-speed maglev transportation system at a speed of 600 kilometers per hour is a key special topic of the "Advanced Rail Transit" national key research and development plan of the Ministry of Science and Technology. The project is organized by CRRC, CRRC Sifang Co., Ltd. is responsible for the technology, gathers domestic high-speed rail and maglev resources, and collaborates with more than 30 companies, universities, and research institutes to tackle the key problems. The purpose is to overcome the core technology of high-speed maglev and develop independent The intellectual property rights high-speed maglev engineering system with a speed of 600 kilometers per hour has formed China's high-speed maglev industrialization capability. Since the project was launched in July 2016, the project team has broken through the key core technologies 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 for the first time.

According to Ding Sansan, the person in charge of the subject of high-speed maglev and the deputy chief engineer of CRRC Sifang Co., Ltd., high-speed maglev is a strong coupling system including four major systems of 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.
CRRC Sifang and Tongji University and other research units carried out this experiment. On the maglev test line, the test sample car was tested for the first time in joint system, and carried out dynamic operation tests under various working conditions, including different track beams and turnouts, small curves, ramps, zone switching, etc., completed more than 200 seven major projects This project has conducted comprehensive tests on key performances such as suspension guidance, speed measurement positioning, vehicle-rail coupling, ground traction, and vehicle-ground communication.
Ding Sansan said: "Under the multi-operating test conditions, the vehicle's suspension guidance is stable and the operating condition is good. The key technical indicators meet the design requirements and meet the design expectations."
According to reports, the successful trial run of the test sample vehicle achieved a breakthrough from static to dynamic operation, obtained a large amount of key data, and the key performance of the high-speed maglev system and core components was initially verified. Development and optimization provide important technical support. At present, 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, it will promote the continuous innovation and industrialization of the technology, and promote the upgrading of China's high-end equipment manufacturing and the development of 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, which can be used for long-distance transportation, forming high-speed corridors between large hub cities or urban agglomerations, and promoting coordinated development between regions; and suitable for short- and medium-distance passenger transportation, used for commuting in large cities or adjacent in urban agglomerations The inter-city connection of cities will build an economic circle of half an hour to one hour, and promote the development of "integration" and "same urbanization" of metropolitan areas and urban agglomerations.
At the same time, 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 architecture for aviation, high-speed rail, high-speed maglev and urban traffic speed gradients to meet the needs of different people. In 2019, high-speed maglev was included in the national "Outline for the Construction of a Powerful Country" as a frontier key technology. The development of the high-speed maglev transportation system at a speed of 600 kilometers per hour will become an important supplement to China's high-speed transportation, help the implementation and promotion of the strategy of a powerful transportation country, and enrich China's modern comprehensive transportation system to achieve continuous leadership in China's rail transportation technology and seize international competition The strategic commanding height has great and far-reaching significance.
