【Representatives and deputies bring new news】
Science and Technology Daily, Beijing, March 5 (Reporter Xue Yan) On the 5th, Wang Feng, a member of the National People's Congress and vice president of China CRRC Co., Ltd., told a reporter from Science and Technology Daily that the latest CR450 EMU developed in my country has completed the prototype design and successfully launched, and is currently undergoing type tests in the Beijing Ring 188bet app.
Wang Feng introduced that the CR450 EMU technology has achieved comprehensive iteration and upgraded, with an operating speed of 400 kilometers per hour, achieving the fastest in the world.
"In terms of speed, we have made all-round technical improvements in traction capabilities, dynamic performance, bow nets, etc.." Wang Feng said that the traction system of the EMU uses water-cooled permanent magnet traction and uses a new high-stability and reliable bogie. Through multi-system comprehensive technological innovation, the train can continue to operate at a speed of 400 kilometers per hour.
To make the car run fast and steadily, it is inseparable from the support of "multi-level emergency braking control technology". Wang Feng introduced that there are more than 4,000 monitoring points all over the EMU, which can conduct holographic real-time monitoring of key states such as walking parts, vehicle bodies, high-voltage pantographs, train controls, and fireworks.
"Energy saving is also a highlight of the CR450 EMU." Wang Feng said that the train adopts a bogie area cladding structure design for the first time, which greatly reduces the air resistance under high-speed operation. It also uses a large number of lightweight new technologies and new materials to reduce the operating resistance of the entire EMU by 22% and reduces weight by 10%.
Not only that, the EMU also has significant advantages in noise reduction. Wang Feng said that the train used seven new noise reduction technologies for the first time, and the noise inside the car was reduced by 2 decibels, which can provide passengers with a comfortable ride experience.
"At the same time, we have also carried out intelligent transformation of the EMU." He said that at present, the CR450 EMU is generally better than other trains in terms of driving and control, driver intelligent interaction, safety monitoring, and passenger intelligent services.
Wang Feng said that the development of the CR450 EMU has successfully built a technical system of EMU with a speed of 400 kilometers per hour, achieving comprehensive innovation in theory, technology, equipment, standards and management models, and injecting new vitality into promoting the innovative development of world high-speed rail technology.
