The First Carbon Fiber Metro Train Has Officially

　　 The car body of "Carbon Star Express Rail" is mainly black, purple, yellow and blue. The black carbon fiber seats, armrests and cab console inside the car are full of science and technology. Of course, the "black technology" of the "carbon star fast track" is far more than that.

　　 The car body, bogie frame and other main load-bearing structures of the "Carbon Star Express Rail" are all made of carbon fiber composite materials, which is the first commercial passenger carrying application of carbon fiber composite materials on the main load-bearing structure of metro vehicles in the world. Compared with the traditional subway, this carbon fiber subway train has achieved a new upgrade, and has significant advantages such as lighter and more energy-saving, more comfortable to ride, higher strength, less wheel rail wear, and lower operation and maintenance costs.

　　 Lighter and more energy-saving

　　 By using carbon fiber composite materials, the car has achieved substantial "slimming". Compared with traditional metal material vehicles, the weight of the car body is reduced by 25%, the weight of the bogie frame is reduced by 50%, and the weight of the whole vehicle is reduced by about 11%. The car body is lighter, running is more energy-saving, and the running energy consumption is reduced by 7%. Each train can reduce carbon dioxide emissions by about 130 tons every year, equivalent to 101 mu of afforestation.

　　 More comfortable to ride

　　 Thanks to the use of carbon fiber composite materials, the vehicle has better vibration reduction and isolation effects and can drive more smoothly. Active radial bogie technology is adopted for the first time in the field of commercial metro trains, which can actively control the wheels to pass along the radial curve, greatly reducing the "squealing" when passing curves. The noise of curve passing is reduced by 15 decibels, and the noise inside the vehicle is reduced by 2 decibels, making the operation quieter.

　　 Higher strength

　　 Compared with the metal car body, the carbon fiber car body has stronger strength and higher safety factor. At the same time, the bogie frame made of carbon fiber composite material has stronger impact resistance, more fatigue resistance and longer structural life.

　　 Less wheel rail wear

　　 The lighter carbon fiber body reduces the axle load of the vehicle, and reduces the wheel rail force by more than 15%, thus reducing the wheel rail wear. The use of active radial bogies also reduces the wear on wheels and rails.

　　 Lower operation and maintenance costs

　　 The wheel rail wear is less, and the maintenance amount of vehicle wheel set and track is greatly reduced. At the same time, the vehicle applies digital twin technology to build a carbon fiber train SmartCare intelligent operation and maintenance platform, realizing intelligent detection of vehicle faults, intelligent assessment of health status and optimization of repair system, and reducing maintenance costs. Through the adoption of new materials and technologies, the cost of life-cycle maintenance of the vehicle is reduced by 22%.
