Commercial maglev enters "2.0 era"
China's first commercial maglev version 2.0 train ran 160 kilometers per hour on the Changsha Maglev Express on April 28, and successfully completed the speed test of the highest design speed. This test has once again set a world record for the operation speed of low and medium-speed maglevs with short stators, marking a major success for China's independent maglev technology in the mid-speed field. China's commercial maglevs have entered the 2.0 era.
In June 2018, based on the experience of development and operation, CRRC Zhuji Corporation and Hunan Maglev Technology Research Center led the joint development of more than 20 units to develop China's first commercial maglev version 2.0 train. Compared with the "Maglev 1.0" version of the commercial operation of the Changsha Maglev Express Line launched in May 2016, the suspension capacity of the 2.0 version increased by 6 tons, the traction power increased by 30%, and the speed increased by 60%.
Tong Laisheng, Director of the Maglev Research Institute of CRRC Corporation, introduced that the Maglev version 2.0 train was developed in accordance with commercial operation standards and tested and verified on the commercial operation line. Its maximum operating speed has reached the design level, and all vehicle operating indicators are Complying with the requirements of the standard indicates that China's medium-speed maglev transportation system already has engineering application conditions. The speed measurement process overcomes major technical difficulties such as medium-speed suspension stability, axle-bridge coupling, and shoe-rail coupling, and overcomes the difficulties of high test risk, no successful case reference, and short night skylight operation time.
Liu Youmei, academician of the Chinese Academy of Engineering and director of the expert committee of CRRC Zhuzhou Machinery Co., Ltd. said that at present, China has established a completely independent intellectual property commercial maglev system from technology research and development, manufacturing, test verification to commercial operation.
It is reported that the maglev version 1.0 train at a speed of 100 kilometers per hour is suitable for urban areas, and the maglev version 2.0 train at a speed of 160 kilometers per hour is suitable for transportation between the central city and the satellite city. At present, CRRC Zhuji Machinery Co., Ltd. is taking the lead in accelerating the development of a maglev version 3.0 train with a speed of 200 kilometers per hour for intercity traffic.
