Japanese media said the world's largest railway vehicle manufacturer, China's car group, disclosed a new generation of metro vehicles using carbon fiber reinforced plastic. The car is bold and lightweight to reduce weight by 13%, which will promote the energy saving of vehicle operation.
The vehicle will also promote automatic driving and vehicle informatization to improve convenience and operational efficiency.
At the world's largest railway exhibition, the international Rail Transit Technology exhibition in Berlin (Innotrans), the Chinese car shows the new generation of Metro vehicles ' Cetrovo ' that is being developed, according to the Japan Economic news September 21. At the international rail Transit Technology Fair in Berlin, the Chinese car quartet released a new generation of carbon fiber Metro vehicles ' Cetrovo '.
Xinhua Cetrovo's body, seat, bogie frame and other carbon fiber reinforced plastics were reported. The body itself is expected to lose 35% weight. Rail vehicles generally use aluminum and stainless steel to manufacture the bodywork, but the components will be adjusted in the future to further promote lightweighting.
The ' inverter ', which controls the vehicle, will use silicon carbide (sic) materials with less power consumption, increasing energy efficiency by 15% compared to previous vehicles. Reporters understand, China car President Sun Yongcai at the time of the vehicle unveiling ceremony said, Cetrovo as the world's first all-carbon composite car body subway, embodies a number of modern advanced design concepts and the use of new systems, new materials, structures, new technology, to achieve the vehicle light weight, automatic driving, intelligent operation and intelligence services,
The material revolution and technological upgrading of rail transit equipment will be vigorously promoted. ' Smart train ': Video on Windows.

According to Chinese vehicle scientists, Ting, Deputy chief engineer of China Automobile Sifang AG, Cetrovo car body, bogie frame, driver's room, equipment cabin and equipment body are made of carbon fiber composites, compared with traditional metal materials, the new generation vehicle weight reduction 13%. Ting said that although the manufacturing cost of carbon fiber composites is higher than traditional metal materials, it has obvious energy-saving advantages, and has the characteristics of fatigue resistance and corrosion resistance, which can reduce the maintenance amount during the service period of the train. He also described the Cetrovo as a ' variable ' metro that can be flexibly grouped according to operational needs ' 2+n ' section, which also has a high level of intelligence, can be used to brush video on the windows, and passengers can just touch the window with their fingers and watch the news on the Windows, surf the Web, buy tickets, swipe videos, watch live TV, etc.
Compared with the traditional subway, the new generation of Metro vehicles can adapt to the more severe climatic environment, can be in high temperature and humidity, -40℃ Alpine, 2500 meters high altitude and other complex environment operation. In addition, the vehicle uses advanced noise reduction technology to ride more comfortably.
