At the Berlin International Rail Transit Technology Exhibition held in Germany, CRRC Sifang (5.410, -0.01, -0.18%) officially released a new generation of carbon fiber subway vehicle 'CETROVO'.
The biennial InnoTrans is considered to be the most important and comprehensive railway and rail transit industry achievement exhibition in the world. At the real car conference held on the same day, Chinese Ambassador to Germany Shi Mingde, China CRRC President Sun Yongcai, German technical expert Hu Fenbach, China's vice president of CRRC Wang Jun, general manager of CRRC Sifang Co., Ltd. Ma Yunshuang and others jointly unveiled the new car.
China's CRRC scientist, Ding Wei, deputy chief engineer of CRRC Sifang Co., told reporters that the new generation of subway vehicles uses advanced carbon fiber technology, car body, bogie frame, cab, equipment compartment and equipment body, etc. Material manufacturing is a metro vehicle that uses carbon fiber composite materials on a large scale. 'In particular, it successfully breaks through the key technologies of large-scale complex design of carbon fiber, manufacturing and molding, and realizes the carbon fiber composite material in the vehicle body, the bogie frame, the driver's cab and other vehicle owners. Full application of the load bearing structure'.
According to reports, compared with traditional metal materials such as steel and aluminum alloy, the body, driver's cab and equipment cabin of the new generation of carbon fiber subway vehicles are reduced by more than 30%, and the weight of the bogie frame is reduced by 40%. In order to reduce energy consumption, in addition to carbon fiber lightweight technology, a new generation of subway vehicles is equipped with a new energy-efficient traction system; from the asynchronous motor of the traditional subway to the direct-drive technology of permanent magnet synchronous motor, and using silicon carbide converter, Greatly improve the traction efficiency of vehicles. According to estimates, the new generation of subway vehicles can be more than 15% energy saving.
It is reported that in addition to the use of new materials, the new generation of subway vehicles also have greater applicability, comfort and intelligent experience. Next, a new generation of carbon fiber subway vehicles will carry out type tests and conduct line trial runs.
China CRRC said on the same day that it will further deepen the research and verification and engineering application of carbon fiber materials on 600 km high-speed maglev trains, high-speed EMUs and subways.
