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.

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.

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. The high-speed maglev with a speed of 600 km / h fills the speed gap between high-speed rail and air transportation. It can form a multi-dimensional traffic structure with more reasonable, efficient, flexible and convenient air, high-speed maglev and urban traffic speed gradient to meet the travel needs of different people. 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.
