The world's first rare earth permanent magnet maglev rail transit project test line completed

8月9日9时30分，一列披着56颗星星的红白空轨列车悬浮在蓝色的轨道下缓缓驶出，由江西理工大学牵头，与兴国县人民政府联合中铁六院、中铁工业、国家稀土功能材料创新中心等单位共同完成的永磁磁浮轨道交通工程试验线——“红轨”在赣州市兴国县正式竣工。

Led by Jiangxi University of Science and Technology, a red-and-white skytrain draped in 56 stars pulled out of the sky at 9:30 PM on August 9, floating under the blue track. The permanent magnet maglev rail transit project test line -- "Red Rail", jointly completed with Xingguo County People's Government, China Railway Sixth Institute, China Railway Industry, National Innovation Center for Rare Earth Functional Materials and other units, has been officially completed in Xingguo County, Ganzhou City.

“红轨”是迄今为止建成的世界首条永磁磁浮轨道交通系统工程试验线，试验线的建成标志着一个安全、便捷、高效的中低速、中低运量的新制式轨道交通系统诞生，具有完全自主知识产权。

"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, which has completely independent intellectual property rights.

创新“红轨”新在哪儿

What's new about the "red Track" of innovation

“作为国际稀土永磁磁浮轨道系统的开拓者、永磁磁浮技术与轨道交通相结合的探索者，‘红轨’有望成为一种全生命周期成本低、性价比优的品质化、个性化、智能化交通运输系统，‘红轨’涵盖新材料、轨道交通、人工智能、无线通信、智能制造、电机驱动等多个战略性新兴产业。”竣工现场，江西理工大学党委书记、红轨技术首席专家杨斌介绍道。

"As the pioneer of the international rare earth permanent magnet maglev rail system and the explorer of the combination of permanent magnet maglev technology and rail transit, the 'Red rail' is expected to become a quality, personalized and intelligent transportation system with low life-cycle cost and excellent cost performance. The 'red rail' covers a number of strategic emerging industries such as new materials, rail transit, artificial intelligence, wireless communications, intelligent manufacturing and motor drive." At the completion site, Yang Bin, Party secretary of Jiangxi University of Science and Technology and chief expert of red rail technology, said.

据了解，“红轨”由稀土永磁悬浮系统、直线电机牵引驱动系统、智能定位与通信信号系统、运行控制与安全保障系统、轨道支撑与牵引供电系统、车辆装备系统等六大部分组成。“红轨”实现了零功率悬浮、低功耗运行；运行过程中不产生废气排放和电磁辐射，对人体和环境无伤害；应用5G通信、北斗定位、智能传感等信息技术，深度互联和智能融合列车、乘客、环境、设备等实体信息；有独立路权，不受其他交通工具的干扰；系统能耗和运维成本小，90%的材料可以循环利用。

It is understood that the "red rail" 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 system, track support and traction power supply system, vehicle equipment system and so on. The "red rail" realizes zero-power suspension and low-power operation. No exhaust emissions and electromagnetic radiation are produced during operation, and no harm is done to human body and environment. The application of 5G communications, Beidou positioning, intelligent sensing and other information technologies, deep interconnection and intelligent integration of train, passenger, environment, equipment and other physical information; Having independent right of way, free from interference by other means of transportation; The energy consumption and operation cost of the system are small, and 90% of the materials can be recycled.

此次建成的试验线正线长度约800米，均为钢构高架线。磁浮列车采用2辆编组，载客能力为坐席32个、定员88人，最高设计运行速度为80千米每小时。

The length of the completed test line is about 800 meters, all of which are steel structure elevated lines. The MAGLEV trains are arranged in groups of two, with a passenger capacity of 32 seats and a seating capacity of 88, and a maximum designed running speed of 80 kilometers per hour.

新一代交通运输系统前景在哪儿

What are the prospects for a new generation of transportation systems

记者了解到，该试验线因处于革命老区“将军县”——兴国县，被誉为“红轨”。磁浮列车命名为“兴国号”，两侧车头标有56颗星星，寓意为向“将军县”56位开国将军致以崇高的敬意。

Reporters learned that the test line is in the old revolutionary base area "General County" - Xingguo County, known as the "red track". The maglev train is named "Xingguo", with 56 stars on both sides of the front, which means to pay high respect to the 56 founding generals of "General County".

中铁科工集团空轨事业部总经理徐国学告诉记者，从“空轨”到“红轨”，转向架由轮胎变成永磁铁，无需耗费电能，通过永磁特性即可实现车辆悬浮，零摩擦运行。为了解决列车行驶过程中永磁悬浮高度不断变化的关键难题，研发团队研制出可浮动偏心轴导向轮结构，让永磁悬浮空轨更安全、更智能。

Xu Guoxue, general manager of air rail division of China Railway Science and Engineering Group, told reporters that from "empty rail" to "red rail", the bogie becomes a permanent magnet from the tire, which does not need to consume electric energy, and can realize the vehicle suspension and zero-friction operation through the permanent magnet characteristics. In order to solve the key problem that the permanent magnet suspension height changes constantly during the train running, the research and development team developed the floating eccentric shaft guide wheel structure to make the permanent magnet suspension air rail safer and more intelligent.

中国中铁股份有限公司党委常委、副总裁李新生表示，中国中铁为“红轨”项目的勘察设计、装备制造、工程施工和运行维护提供了一揽子综合解决方案。“‘红轨’试验线的竣工不仅是项目各方深入贯彻国家‘交通强国’战略的积极探索，而且为我国构建多层次、一体化、智能化、现代化轨道交通网开启了新的里程碑，也为革命老区的发展增添了新动能。”李新生说道。

Li Xinsheng, a member of the Standing Committee of the CPC Committee and vice president of China Railway Corp, said the company has provided a comprehensive package of 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 by all parties involved in the project to thoroughly implement the national 'transportation power' strategy, but also opens a new milestone for the construction of a multi-level, integrated, intelligent and modern rail transit network in China, and adds new impetus to the development of the old revolutionary base areas." "Li said.

“‘红轨’将引领绿色交通与低碳出行，重构高质量发展新产业生态，具有广阔发展前景。”杨斌说道。

"The 'red rail' will lead green transportation and low-carbon travel, reconstruct the high-quality development of new industrial ecology, and has broad development prospects." "Yang Bin said.

据介绍，科技部在“十四五”“交通载运装备与智能交通技术”重点专项中，将“低成本中小运量磁浮客货运输系统技术与装备”项目列入了项目指南，计划于2024年启动。

According to the report, the Ministry of Science and Technology has listed the project of "Technology and equipment of Maglev passenger and cargo transport system for low cost and small volume" in the key special project of "Transportation Equipment and Intelligent Transportation Technology" in the 14th Five-Year Plan, which is scheduled to start in 2024.
