China’s next-generation subway train completes trial run through expert acceptance

December 19 news (reporter Wang Wei correspondent Deng Wangqiang) December 17, the Ministry of Science and Technology High-tech Division in Qingdao organized a project acceptance meeting, China Motor Quartet Co., Ltd. led the responsibility of the national science and technology support plan – the next generation of subway train project successfully passed the expert group acceptance. This marks the latest technological achievements in the field of subway trains in China.

At the acceptance meeting, 13 experts and scholars from domestic research institutes, universities and enterprises formed an acceptance expert group to review the project. Through on-site view of the prototype, listen to the project results report and after questioning discussion, the expert group agreed to the project through acceptance.

According to the introduction, the next generation of subway trains is a new generation of subway sdevelopment for future application sdevelopment. Research and development will be launched in 2015, prototype series will be assembled and offline in 2018, and in-plant testing will be completed in June 2019, and the actual operation line Guangzhou Metro Line 8 will be completed in September. From the start of research and development to through acceptance, before and after four years of attack.

The next generation of subway trains adopt a large number of advanced new materials, new technologies, new systems, compared with the traditional subway, with lighter, more energy-saving, more comfortable, more intelligent, more adaptable and other significant technical advantages, representing the future development of subway vehicles technology development, with the “future subway” said.

The body is lighter. The vehicle uses advanced carbon fiber technology, the body, steering frame, driver’s compartment, equipment compartment, etc. are made of carbon fiber composite materials, the first time to achieve the full application of carbon fiber composite materials in the main structure of the train, the vehicle weight loss of 13%.

Run more energy efficiently. A “lighter” body reduces operating energy consumption. At the same time, the use of new silicon carbide permanent magnetic synchronous traction system, pneumatic drag-absorbing design and regenerative braking full feedback and other energy-saving technologies, the overall energy saving of the train reached 30%.

Ride more comfortablies. The vehicle uses new noise-cancelling materials, structures and technologies, reducing noise in the vehicle by more than 5 decibels. At the same time equipped with a fully active suspension system, the train runs more smoothly.

More intelligent. The car has a top operating speed of 140 kilometers per hour, faster than the regular subway, and is fully autonomous. The passenger system is also smarter. The windows are transformed into a touch display, where passengers can surf the Internet, buy tickets, watch the news, swipe video… Not only that, the vehicle adopts advanced intelligent operation and maintenance technology, realizes holographic real-time state monitoring, in-transit early warning and active operation and maintenance, and the vehicle’s operation and maintenance is more intelligent.

More adaptable. Unlike traditional metro fixed formations, the car can be “flexiblely grouped” and can be combined with cars in any range of 2 to 12 knots, improving operational efficiency and reducing operating costs. At the same time, adapt to the more harsh operating environment, can be high temperature cold, high altitude, small curve, large ramps and other conditions.

It is reported that the next generation of subway trains in the actual operation line to complete the line test and operation demonstration, successfully passthe acceptance, with industrialization capacity. In the future, the application of the next generation subway train technology will lead to the re-upgrading of subway vehicle technology in China.
