The same are the locomotives of the train, but the shape of Japan and the mainland is very different, so in the design of the front of the train, who will perform better than the mainland and Japan? In the design of the locomotive of the train, why doesn't the mainland use the same platypus shape as Japan?
High-speed rail technology has now become a famous brand in the world by the mainland and has become the endorsement of Chinese manufacturing. But is the mainland only high-speed rail technology famous in the world? No, the mainland's trains have also been widely recognized by the international community. In terms of the front of the train, the mainland uses a more common bullet.
However, there are exceptions in the front design, such as Japan, where the front of the Japanese EMU looks very new and flat, just like the platypus.
The same is the front of the EMU, which is very different between China and Japan
The train has now become the first choice for many people to travel remotely, not to mention holidays, even if it is an ordinary day, the train station is crowded. For many people, the train is estimated to be very familiar, especially the front of the bullet.
This kind of bullet train is actually still very common, basically no matter which country we go to take the train, the bullet can not run. However, there is one country that is an exception, this country is Japan, if you run to Japan to take the train, you can definitely find that the front of the Japanese train is flat and long, so it is also called "platypus".
So, if you make a comparison between the two different shapes of the continental and Japanese embosses, which one would be better?
The two kinds of moving locomotives in China and Japan, who is better?
In fact, just as the so-called existence is reasonable, the advantages and disadvantages of the two kinds of locomotives in the mainland and Japan actually need to be analyzed on a case-by-case basis. Let's start with Japan. What about the Japanese platypus locomotive? For Japan, in fact, it is not bad, and the trains are all through the tunnel.
Japan's tunnels are different from the mainland, the cross-section is relatively narrow, resulting in high-speed air friction, and then there will be a harsh roar, more importantly, Japan's trains and mainland uses are also different. On the mainland, the use of EMUs is basically long-distance travel. The main purpose of the emergence of Japanese trains is to facilitate the commuting of local residents, so the train station is not very far from the residential area. Such a huge noise will have a great impact on the lives of local residents in Japan.
However, if replaced by a flat and long platypus, it is different, and the 20-meter-long platypus front can expand the friction surface with air, thereby dispersing and reducing noise. Moreover, in the event of an accidental derailment of the train, the Japanese platypus locomotive can act as a pioneer and reduce casualties among passengers.
Let's talk about the mainland, the mainland uses a bullet train, this head of the train can reduce air resistance when entering the tunnel, can reduce various air waves and noise, so that the speed of the train is faster, so we can find that in terms of the speed of the train, Japan's top sky is only 320 kilometers per hour, and the mainland can reach 350 kilometers.
In addition, the use of bullets in the mainland of the EMU, compared with the Japanese platypus, can leave more space, can increase the number of passengers in the EMU, which is the most reflected in the statutory holidays.
In short, the shape of the head of the train in mainland China and Japan is actually not about who is superior and who is inferior, it can be said that in their respective environments, they have their own unique advantages. However, the EMU technology originated in Japan, the world's first EMU is also in Japan, the mainland in the development of EMU, also learned from Japan, I think that when Deng Xiaoping visited Japan, he also experienced the Japanese EMU.
It can be said that when the mainland developed the train, there were Japanese shadows everywhere, so why did the mainland only learn Japan's Shinkansen technology and not even the Japanese EMU locomotive?
Why don't the front of the mainland EMU use the Japanese "platypus"?
Why doesn't the mainland learn from Japan's "platypus" EMU locomotives? The reason is also very simple, first of all, it is not necessary, why Japan wants to design a platypus, it is not because after Japan builds the tunnel, the cross-section of the tunnel is too small, and the cost of rebuilding is too high, so it can only be cut at the front of the train, which is purely helpless.
But does the mainland need to do such a helpless move? In fact, it is not necessary, it is said that at that time, when Japan was too narrow because the cross-section of the tunnel was too narrow, the mainland was still building a tunnel, and after hearing about this incident, the mainland deliberately designed the cross-sectional area to be wider in the construction of the tunnel. Therefore, there is no case of tunnel cross-section being too narrow and making too much noise on the mainland.
Moreover, even if there is noise on the mainland, it is not afraid, because whether it is a tunnel or a train station, it is basically set up in a remote suburb, and it is not as close to a residential area as japan, so in general, there is really no need for a whole "platypus" locomotive.
In addition, Japan's more than twenty meters of platypus locomotive, not only waste materials, but also waste money, but also affect the speed, the only advantage over the bullet is that the noise reduction performance will be better. However, the mainland is sparsely populated, do you need noise reduction? Then, if the front of the car of more than twenty meters is really placed on the mainland train, it can be said that it is useless. On the contrary, the white flowers also flowed away a lot of real money and silver. Therefore, why the continental EMU locomotive is not used and does not learn the Japanese platypus form is also estimated to take into account the economic cost-effectiveness aspect.
summary
In terms of the locomotive of the train, Japan is a platypus, the mainland is a bullet, the two in the end who is superior and who is inferior is actually uncertain, there is a saying how to say, orange sheng Huainan is orange, born in Huaibei is orange, specific problems are actually to be analyzed in detail. However, in terms of aesthetics, I personally feel that the bullets of the mainland are better.
