Key technologies of high-speed passenger transport equipment at speeds of 400 kilometers per hour and above

Recently, the key special management office of the "Advanced Rail Transit" (hereinafter referred to as the "Special Office") of the High-tech Center organized experts to conduct a mid-term inspection of the "Key Technology of High-speed Passenger Transport Equipment with a Speed ​​of 400 km / h" led by CRRC. A total of more than 40 people participated in the meeting, including the Jilin Provincial Department of Science and Technology, experts from the special group, peer experts, project lead list, main members of participating units, and relevant members of the special office.

This inspection uses a combination of meeting and on-site inspection. At the meeting, the special office introduced the principles and objectives, contents and procedures of the mid-term inspection. The person in charge of the project reported on the overall progress of the project, the highlights of the project, the organization and management, the implementation of funds and the follow-up work plan. The expert team inspected on-site the relevant technical achievements obtained by the project lead unit, as well as the manufacturing, R & D test platforms and equipment of complete vehicles and key components. The expert group evaluated the overall progress of the project, made recommendations on the project's innovation, implementation progress, collaborative research, and demonstration application conditions, etc., and pre-judged whether the project's goals could be successfully achieved. Expected effect. At the same time, the person in charge of the Science and Technology Department of Jilin Province said that follow-up will give strong support to the smooth development of the project.

At present, the project team has determined the overall technical plan for high-speed passenger transport equipment with a speed of 400 kilometers per hour and above. The system carried out key technology research on wheel-rail relationship of different lines, gauge-changing mechanism, safety inspection, etc., for the first time put forward the overall technical scheme of gauge-changing bogies; developed a prototype of active noise reduction control for business seats; and built an algorithm for assisted driving / Equipment test platform, completed the high-speed train energy-saving optimization control strategy and driver assistance driving device development, and conducted a preliminary test of the line. The project will form a prototype of a 400 km / h high-speed train and a prototype of a variable-structure bogie, which will further improve the capacity of China's rail transportation industry to be put out.
