 New breakthrough! Successful test run of Chinas 600 km high-speed maglev test sample vehicle


The research and development of high-speed maglev transportation system with a speed of 600 kilometers per hour is a key special subject of advanced rail transit under the national key research and development plan of the Ministry of science and technology. The project is organized by CRRC, and is in the technical charge of CRRC Sifang Co., Ltd., which gathers domestic high-speed rail and magnetic levitation resources, and cooperates with more than 30 enterprises, universities and scientific research institutes to tackle key problems. The purpose is to overcome the core technology of high-speed magnetic levitation, develop a high-speed magnetic levitation engineering system with independent intellectual property rights, and form Chinas high-speed magnetic levitation industrialization capacity. Since the start of the project in July 2016, after nearly four years of scientific and technological research, the project team has broken through the key core technology of high-speed maglev series, and successfully developed a test sample vehicle. After the ground commissioning and static test, the vehicle entered the dynamic operation test of the line, the first test run.

According to Ding Sansan, project leader of high-speed maglev and deputy chief engineer of CRRC Sifang Co., Ltd., high-speed maglev is a strong coupling system including four systems of vehicle, traction power supply, operation control communication and line track. Through the line test of sample vehicle, it can preliminarily verify the interface relationship and coupling characteristics between various systems of high-speed maglev under dynamic conditions, which is the key part of the system and core components Performance verification and optimization provide support.

CRRC Sifang cooperated with Tongji University and other research units to carry out the test. In the Maglev Test line, the test sample vehicle is debugged for the first time, and the dynamic operation tests under various working conditions are carried out, including different track beams, turnouts, small curves, ramps, district switching, etc., and more than 200 test points of seven major items are completed, and the key performance of suspension guidance, speed measurement and positioning, vehicle rail coupling, ground traction, vehicle ground communication, etc. are comprehensively tested.

Under the condition of multi working condition test, the vehicle suspension guidance is stable, the operation condition is good, all key technical indicators meet the design requirements, and meet the design expectations. Ding Sansan said.

The successful test run of the sample vehicle achieved a breakthrough from static to dynamic operation, obtained a large number of key data, and preliminarily verified the key performance of the high-speed maglev system and core components, providing important technical support for the development and optimization of the subsequent high-speed maglev engineering sample vehicle.

It is reported that the R & D of high-speed maglev project is progressing smoothly at present, and the development of 5-car marshalling project sample vehicle is steadily advancing. According to the plan, the prototype system of high-speed maglev project with a speed of 600 km / h is expected to be offline by the end of 2020, which will form a complete set of high-speed maglev technology and engineering capacity. In the future, through the construction of High-speed Maglev Demonstration Project and the operation of 600 km / h line, the continuous innovation and industrialization of the technology can be promoted, and the development of Chinas high-end equipment manufacturing upgrading and strategic emerging industries can be promoted.

As a new high-speed traffic mode, high-speed maglev has the advantages of high-speed, fast, safe and reliable, strong transportation force, comfort and punctuality, environmental protection, low maintenance cost and so on. Its application scenarios are rich, which can be used for long-distance transportation, i.e. corridor transportation, forming high-speed corridors between large-scale hub cities or urban agglomerations, promoting coordinated development among regions; it can also be used for medium and short-distance passenger transportation, i.e. commute, urbanization transportation, commuting in large cities or intercity connection of adjacent cities in urban agglomerations, creating half-hour to one hour economy Circle, to promote the integration and urbanization development of metropolitan areas and urban agglomerations.

In 2019, high-speed maglev, as a key cutting-edge technology, was listed in the national outline of building a powerful transportation country. The development of high-speed maglev transportation system with a speed of 600 kilometers per hour will become an important supplement to Chinas high-speed transportation. It is of great and far-reaching significance to help the implementation and promotion of the strategy of building a strong transportation country, to enrich Chinas modern comprehensive transportation system, to realize the continuous leading of Chinas rail transit technology, and to seize the strategic commanding point in international competition.
