China tested the fastest high -speed train in the world

Known as the fastest high -speed train in the world, Cr450 can run at 450 km/h during testing and onions, according to the Chinese Railway Group Company. The engineers at the test center carefully supervise the weight control of the CR450 prototype. To achieve this, they install the sensor on the tracks, transmit weight data in real time for each wheel of 8 wheels on both sides of each ship to the computer system. This allows accurate monitoring and adjustment to ensure optimal performance, CGTN On 23/2 reported.

“While reducing weight, we must ensure the durability of the ship does not decrease. We even need to increase the durability due to running at a higher speed. It is very similar to a person who wants to lose weight while increasing strength. Durable. The process includes structural changes and innovation in materials, “Chen Can, researcher at the Locoa Research Institute and the means of the Chinese Railway Academy (Cars) shall.

In order to reduce air resistance while operating at high speed, the team overcame many challenges such as resonance and heat dissipation and first closed the entire shifting price area below the ship. Ensuring the smooth operation of the entire hull helps minimize the obstacle when operating, according to Ha Dalei, the designer at the Railway Traffic Technical Research Center of Truong Xuan Railway Company. The CR450 prototype has completed the static and dynamic test at low speed in terms of grip, brake force and noise. The next step is to gradually increase the speed in the testing test.

Currently, China is the only country in the world operating high -speed commercial railway at 350 km/h. Next, they will increase the speed of 50 km/h, reaching 400 km/h. According to Zhang Bo, director of the Loco and Motor Research Institute in Cars, since 2018, the research team spent a few years checking technical feasibility, determining reasonable technical standards and reasonable and reasonable technical standards and Overcoming difficulties. On the one hand, the goal is to reach a higher speed and safer operation. On the other hand, they spend a lot of effort to reduce resistance and consume energy, eliminate vibration and noise, and enhance automatic and super light.

The above efforts help the hull smoother, improve aerodynamic and significantly reduce resistance. The CR450 applies many technical measures that causes the resistance to decrease by 22%. According to Zhang, the speed of the high -speed train is not only a technical issue but also the economy and need to consider impact on the environment. However, the speed is still the most obvious factor of the high -speed rail efficiency.
