News from this site on March 30, according to "China Maglev" news, at 15:06 pm on March 29, 2024, China Railway Construction led the investment and construction, The Qingyuan maglev train designed by China Railway Fourth Institute, operated by Qingyuan Maglev Transportation Co., Ltd., and designed and manufactured by CRRC Changchun Rail Passenger Vehicle Co., Ltd., conducted a speed test on the uplink line of the Qingyuan maglev tourist line between Hudiewan and Changlong, Achieved a maximum operating speed of 132.9km/h.

## This site inquiry and learned that Qingyuan City's Magnetic Floating Travel Line is Guangdong's first low -speed magnetic floating tourist route. km, connecting the Guangqing intercity Yinzhan Station and Qingyuan Chimelong Scenic Area , with three maglev stations: Yinzhan Station, Hudiewan Station, and Maglev Chimelong Station. The special line train is composed of 3 cars and can achieve 3 3 In heavy-duty operation, the vehicle design speed is 120km/h.

This time it was carried out in the Hudie Bay-Changlong section The train's maximum operating speed test and overspeed protection test at structural speed were conducted to verify that the Qingyuan maglev train can reach the design speed of 120km/h, and that under the 120km/h operating speed, traction and braking , suspension and other system performance meet the design requirements.

During the speed test, the train was running at a design speed of 120km/h, then accelerated to 125km/h, 128.7km/h, and finally exceeded the design structural speed to 132km/h, or even 132.9km. /h. This process involves traction, braking, suspension, dynamic performance, etc. Everything is normal and can meet the requirements of the vehicle technical specifications. The test was successfully completed.

CRRC Tangshan Company stated that the Qingyuan maglev train uses normal conduction electromagnetic levitation and short stator linear motor traction technology, with a magnetic track gauge of 1860mm and a design speed of 120km/h. The train adopts a centralized two-point suspension control system, excellent aerodynamic streamlined design, and a safe and reliable pure hydraulic braking device. It relies on the electromagnetic attraction generated by the normally conductive magnets "held" under the rail row and the rail row to make the train float. Starting from about 8-10mm, it is driven by a linear motor, without vibration and friction between the wheel and the track; it has the technical advantages of "small turning radius and strong climbing ability" and the cost-effective advantage of "low engineering cost and low operation and maintenance cost". As well as green and environmentally friendly advantages such as safety, low carbon, and low noise, the vehicle has completely independent intellectual property rights throughout the entire industry chain, and its technical indicators are at the forefront of maglev transportation .

The above is the detailed content of The Qingyuan maglev train has a maximum operating speed of 132.9km/h. For more information, please follow other related articles on the PHP Chinese website!
