Why is the high-speed railway shaking more and more? Ferruginous peduncle

In the theory of relativity, two high-speed trains run at high speed when they cross. Suppose that one of the two cars is stationary, and the other is passing by at the speed of the two cars. High speed running will produce airflow, which is aerodynamic, airflow

Does the high-speed railway shake more and more?

When the Xi'an Nanjing high-speed railway is approaching Sudong, it runs at a speed of about 300 kilometers per hour. It seems that there is no obvious swing in the carriage before! I feel that there is a problem! As long as the track viaduct is correct and rigorous from design to construction, it should not be a problem West

Why is the speed of the high-speed rail slow when it enters the station, but the high-speed rail pole shakes more severely?

Most sections of China's high-speed railway are built on the subgrade of "Wuzha", which is more unstable than "Youzha". Moreover, the design of high-speed railway body is not as stable as that of France's high-speed railway. If there is a settlement range in the subgrade where the high-speed railway passes, it will cause the car body to shake

Why does the high-speed railway sway from side to side during driving?

Because the rail is uneven, although the error is small, it can still be felt. For example, if the left rail is slightly higher, it will sway to the right. Because the rail is uneven, although the error is small, it can still be felt. For example, the left rail is slightly higher

Why does the high-speed railway shake after passing the house?

The high-speed railway shakes when passing the house because of resonance

Why does the shaking of the train or bullet train when it enters the station become more serious than other times?

Because the speed is slow when entering the station, and the track is curved when entering the station, with superelevation, the car will incline. Before entering the station, you have to cross the turnout, and the high-speed rail pole turnout shakes severely because the speed is slow when entering the station, and the track is curved when entering the station

Why is the shaking feeling of entering and leaving the station by high-speed train lighter than that of ordinary train?

Because the high-speed train runs smoothly, if you don't look outside in the trunk, you can't feel it, and the seats are facing forward, because the high-speed train runs smoothly, if you don't look outside in the trunk, you can't feel it, and there are seats

Why is the subway slower than the high-speed railway, but the shaking amplitude is more severe than the high-speed railway, and the high-speed railway stands on the subway

Thanks for the headline invitation. The reason why the subway is slower than the high-speed railway should be very simple. The subway runs underground in the city for two or three minutes, and dare not run too fast. The high-speed railway is different. The distance between each station is far, so One

Will you get carsick on the high-speed railway

No, the high-speed railway is relatively stable. I'm also super carsick. I don't shake too much. I'm not too dizzy looking out the window

What's the difference between high-speed rail and train?

The difference between ordinary high-speed trains is that they are stable. The high-speed railway runs very smoothly, and the high-speed railway stems basically move forward at a uniform speed. It's not like an ordinary train swaying from side to side at any time. High iron peduncle is accurate. The operation time of the high-speed railway is very accurate. In addition to the shutdown caused by geological disasters, the high-speed railway is based on
