A high-speed train with a speed of 350 kilometers per hour, why is there no seat belt at such a high speed, do you know?

We all know that there are seat belts on planes and cars, but there are no seat belts on high-speed trains. Many people don't understand this reason. Compared with these three means of transportation, taking high-speed rail is more stable, because high-speed trains are stably bound on two tracks, and their stability is better. China's self-developed high-speed rail has reached a world-class level, not only The acceleration is fast and stable, the speed is higher, and its safety performance is better. The world's most advanced ballastless rails are used, so that the high-speed rail can release its speed without fear of derailment.

High-speed rail passengers have done such an experiment. They put a cigarette upright on the table of the high-speed rail. When the train accelerates from a standstill to a high speed of 300 kilometers per hour, the cigarette does not fall down, which is amazing. There are also children who have done similar stability experiments. They used wooden building blocks to build a building with a dozen floors on the small table board of the high-speed rail. When the train was running at high speed, the building block building did not collapse. Stability like this is definitely not possible in cars and airplanes. The stability and balance of high-speed rail far exceed the previous two.

Passengers on the plane must install seat belts, mainly to prevent the impact of airflow, especially to prevent the plane from bumping up and down in turbulent flow. fell, causing personal injury. Everyone knows how to wear seat belts. This is to avoid secondary collisions. When the car collides with the object in front, due to inertia, if the passengers in the car do not wear seat belts, they are likely to hit the front. On the steering wheel or seat, it can even be thrown out.

If you take a high-speed train, the chances of passengers being thrown out and being injured are relatively small, and all high-speed trains use crash-proof seats. Any impact on the seat will automatically retract to avoid damage to passengers. The study found that if passengers are tied to the high-speed rail seats with seat belts, in the event of a serious accident on the high-speed rail, these passengers will be restrained by the seat belts, which will cause more damage. There was such an accident on the German high-speed railway. At that time, only 11 passengers were rescued by seat belts, and 88 passengers were damaged by seat belts. Therefore, installing seat belts on high-speed railways does more harm than good. Therefore, China's high-speed railways Seat belts are removed.
