Zhongxin Finance, April 23. According to the China National Railway Group Co., Ltd. (hereinafter referred to as the National Railway Group), a few days ago, my country's independent research and development, the world's leading new Fuxing high-speed comprehensive inspection train went online.
For the first time in the world, the open-track intersection with a single train speed of 435 kilometers per hour and a relative speed of 870 kilometers per hour and a tunnel crossing with a single train speed of 403 kilometers per hour and a relative speed of 806 kilometers per hour were successfully realized. law.
As a new technology verification platform for high-speed EMUs, the car participated in the preliminary test of the development of CR450 EMUs. On April 12, in the Badong-Wanzhou section of the Zhengzhou-Chongqing high-speed railway, it successfully achieved a single-train speed of 403 kilometers per hour in the tunnel and a relative intersection speed of 806 kilometers per hour; On April 21, the Puyang-Zhengzhou section of the Jinan-Zhengzhou high-speed railway successfully achieved a single-train speed of 435 kilometers per hour on the open line and a relative intersection speed of 870 kilometers per hour, setting a world record for the speed of the high-speed EMU train on the open line and the tunnel.
This marks the full launch of the "CR450 Science and Technology Innovation Project" included in the national "14th Five-Year Plan", which will provide the most important technical support and guidance for the development of the CR450 EMU, and will also provide the most important support for the construction of the 350 km/h safety standard demonstration line and guarantee.
The person in charge of the Science and Information Department of China National Railway Group introduced that the new Fuxing high-speed comprehensive inspection train adopts 9 new technologies such as eddy current braking, carbon ceramic brake disc, permanent magnet traction system, and active control pantograph independently developed by my country. It is composed of EMUs and 4 trailers, which enhances the safety, reliability, efficiency and economy of EMU trains. The overall performance has reached the world's leading level, filling a number of domestic technical gaps.
The above-mentioned person in charge pointed out that the world-leading new Fuxing high-speed comprehensive inspection train was put into operation and a series of scientific experiments were successfully carried out, which verified the performance of the new technology equipment, explored the boundary conditions for the operation of the EMU under higher speed conditions, and further enriched and expanded the The basic theoretical research results and engineering practice experience of my country's high-speed railways are of great significance for improving the self-reliance and self-reliance of railway technology and consolidating my country's leading position in the world of high-speed railways.
