The speed is 4 times faster than the plane. China's super high -speed rail is about to come out. It only takes 2 minutes from Beijing to Shanghai

Vacuum Magnetic Rail Train Imaging Picture

China's super high -speed rail, which is 4 times faster than the aircraft, is about to come out soon. It only takes only two minutes from Beijing to Shanghai. So what is the reason for China to start researching this action speed faster than the aircraft 4 4 4 4. 4 Double ultra -high -speed flight train?

Beijing Magnetic Suspending Train

China wants to develop and build an ultrasonic speed train with a speed of 4,000 kilometers per hour. The reason is actually very simple: if China can make this ultra -high -speed train form a train network and cover most of China's urban agglomerations, and now in large cities in large cities The subway orbit is seamlessly connected, which will mean that the one -hour activity circle of the Chinese people in the future will greatly increase, which will mean The ultra -high -speed train network will also become another new business card in China after the aerospace, high -speed rail and nuclear power generation system.

Although such a high -speed network can effectively improve the living standards of Chinese people and the economic development capabilities of this country, it is not easy to build such an ultra -high -speed city network; because China cannot use the two magnetic suspension train technology and vacuum pipeline technology The practicality of item technology is that there is no way to build a vacuum pipeline and train operation system that allows the train to run at 4,000 kilometers per hour.

Moreover, if China wants to establish an ultra -high -speed train carrier system, in addition to overcoming the above technical difficulties, it also needs to solve another more troublesome problem: how to ensure that passengers have passengers during the process of accelerating and deceleration in the process of acceleration and deceleration. A good enough experience: Because the train runs at 4,000 kilometers per hour, if the proportion of converted to the speed of sound is 3.3 times the speed of sound, which means that the speed of the ultra -high -speed train at 4,000 kilometers per hour in China is the speed of running. The maximum flight speed of the machine is equal.

If the train needs to turn around under such high -speed operation, even if it is only a small curve like 0.5 degrees, it will also cause great pressure to the passengers' bodies. Then, the influence of the deceleration process on the passenger during the train driving process, as well as the acceleration changes caused by the turning of the train, also need to become the most important problem that researchers need to consider when they are developing and deploying such ultra -high -speed train pipe networks. one.

Especially under the premise that China has gained a lot of experience in the research and development and use of magnetic suspension trains, it is not difficult to push the speed of magnetic suspension trains to the current theoretical limit, but the real question is how to ensure that the vacuum pipeline system can be necessary to be necessary Under the premise of opening and closing, keeping the interior is in a low pressure state, and how people should quickly position the trains in the vacuum when the train is accidentally, and to ensure that the life of the passengers in the train in the tube is presented in a negative pressure state. If these problems can be resolved, China will be able to completely solve all problems how to make the train reach 4,000 kilometers per hour, and in the future, it will gradually put it into reality
