At 9:30 on August 9th, a red and white sky rail train with 56 stars suspended under the blue track and slowly drove out. The permanent magnet maglev rail transit project test line - "Red Rail" jointly completed by the industry, the National Rare Earth Functional Materials Innovation Center and other units was officially completed in Xingguo County, Ganzhou City.
"Red Rail" is the world's first permanent magnet maglev rail transit system engineering test line built so far. The completion of the test line marks the birth of a safe, convenient and efficient new standard rail transit system with medium and low speed and medium and low volume. Has completely independent intellectual property rights.
Where is the new "red track" of innovation
"As the pioneer of the international rare earth permanent magnet maglev track system and the explorer of the combination of permanent magnet maglev technology and rail transit, 'Red Track' is expected to become a quality, personalized, intelligent, low-cost and cost-effective throughout the life cycle. The 'Red Rail' covers a number of strategic emerging industries such as new materials, rail transit, artificial intelligence, wireless communications, intelligent manufacturing, and motor drives." The completion site, Secretary of the Party Committee of Jiangxi University of Science and Technology, Chief Expert of Red Rail Technology Yang Bin introduced.
It is understood that the "red track" consists of six parts: rare earth permanent magnet suspension system, linear motor traction drive system, intelligent positioning and communication signal system, operation control and safety assurance system, track support and traction power supply system, and vehicle equipment system.
"Red Rail" realizes zero-power suspension and low-power operation; no exhaust emissions and electromagnetic radiation are generated during operation, and no harm to human body and environment; application of 5G communication, Beidou positioning, intelligent sensing and other information technologies, deep interconnection and Intelligent integration of physical information such as trains, passengers, environment, equipment, etc.; independent right of way, without interference from other means of transportation; low system energy consumption and operation and maintenance costs, and 90% of materials can be recycled.
The main line of the test line built this time is about 800 meters long, all of which are steel structure elevated lines.
The maglev train is composed of 2 cars, with a passenger capacity of 32 seats and a capacity of 88 people. The maximum design running speed is 80 kilometers per hour.
What is the future of the next-generation transportation system?
The reporter learned that the test line is known as the "red track" because it is located in Xingguo County, the old revolutionary area "General County".
The maglev train is named "Xingguo", and there are 56 stars on both sides of the train, which means to pay high tribute to the 56 founding generals of "General County".
Xu Guoxue, general manager of the Air Rail Division of China Railway Science and Industry Group, told reporters that from the "air rail" to the "red rail", the bogie changes from tires to permanent magnets, without consuming electricity, the vehicle can be suspended through the characteristics of permanent magnets, zero friction run.
In order to solve the key problem of the constant change of the permanent magnet suspension height during the running of the train, the R&D team developed a floating eccentric shaft guide wheel structure to make the permanent magnet suspension air rail safer and more intelligent.
Li Xinsheng, member of the Standing Committee of the Party Committee and Vice President of China Railway Group Co., Ltd., said that China Railway has provided a package of comprehensive solutions for the survey and design, equipment manufacturing, engineering construction and operation and maintenance of the "Red Rail" project.
"The completion of the 'Red Rail' test line is not only an active exploration of the project parties to thoroughly implement the national 'transportation power' strategy, but also opens a new milestone for my country to build a multi-level, integrated, intelligent and modern rail transit network. It has added new momentum to the development of the old revolutionary base." Li Xinsheng said.
"'Red Rail' will lead green transportation and low-carbon travel, reconstruct high-quality development of new industrial ecology, and have broad development prospects." Yang Bin said.
According to reports, the Ministry of Science and Technology has included the "Low-cost medium and small volume maglev passenger and cargo transportation system technology and equipment" project in the "14th Five-Year Plan" key project of "Transportation Equipment and Intelligent Transportation Technology", which is planned to be launched in 2024. year start.
