Chapter 365 The shock brought by the ‘Fuxing’ EMU

Beijing West Railway Station.

At this time, West Station is still under construction.

The entire Beijing-Kowloon Railway will have a total of 209 stations, including 193 stations in mainland China and 16 stations in Xiangjiang.

Almost all train stations need to be rebuilt.

Of course, there are so many sites, which does not mean that all sites need to be stopped.

Having many stops is different from stopping at a few stops.

The construction time of these railway stations is relatively long, and it is normal for the construction to take several years.

At this time, the EMU has stopped on the track.

Unlike before, there was only one locomotive that set off. Now there are two locomotives. Another train is pulled to the capital alone, and then the final assembly is carried out in the capital.

"This train is so beautiful, the lines are very smooth." Everyone couldn't help but marvel.

This "Fuxing" EMU is so beautiful, completely different from domestic trains.

At this moment, just looking at the "Fuxing" EMU, they felt a kind of shock.

Just one glance gives them a "high-end and classy" feeling.

Appearance equals combat effectiveness, this is an iron rule.

There is no one who doesn't like beautiful things, unless that person is not a normal person.

"This aerodynamic design of the locomotive took a lot of effort on my part!" Liu Tao pointed at the locomotive and smiled lightly.

A train of rail transit vehicles in operation has complex coupling relationships.

What is a coupling relationship?

Simply put, it refers to the interaction and mutual influence between things. There are complex influences such as resistance, noise, pressure waves, and micro-pressure waves between the car body and the car body, the car body and the bogie, the car body and the pantograph and other on-board equipment, the wheelset and the track, the train and the line facilities. And the interaction relationship is called "fluid-structure coupling" in the field of rail transit vehicles.

The biggest 'enemy' of a high-speed object in motion is not its own weight but the air. In addition to air resistance, the "lethality" of air to rail transit vehicles also includes aerodynamic noise, tunnel micro-pressure waves, and train surface pressure waves. Air resistance is the main way in which air exerts force on high-speed rail trains.

The running resistance of rail transit vehicles includes two parts: friction resistance and air resistance. Friction resistance is directly proportional to the train speed, while air resistance has a square relationship with the train running speed. When the train's speed increases three times, the air resistance will be nine times the original.

When the speed reaches 250 kilometers per hour, almost 80% of the resistance comes from airflow resistance.

Therefore, the front of the "Fuxing" EMU is pointy, like a dolphin, and the overall lines are very smooth. They are processed by high-precision instruments in order to reduce air resistance as much as possible.

With this streamlined design, the smaller the cross-section of the vehicle, the better, and the overall body is reduced in concavity and convexity.

Excellent aerodynamic design, through technical design such as car body slenderness ratio, car body cross-sectional shape, car body cross-sectional area, diversion type, cockpit inclination angle, etc., allows the train to achieve better performance in surface pressure, aerodynamic resistance, aerodynamic lift, intersection pressure wave, aerodynamic The technical performance is superior in terms of noise and other aspects.

After visiting the entire "Fuxing" EMU, Liu Tao led everyone into the carriage.

When entering the car, everyone was shocked by how clean and bright it was.

"These seats can make people sit more comfortably. They can also be adjusted downwards and rotated 360 degrees." Liu Tao demonstrated, "When the EMU arrives at the terminal, there is no need to make a U-turn by going around. Just use another locomotive and adjust the seat directly in the other direction."

After hearing Liu Tao's explanation, everyone suddenly understood why the Fuxing EMU had two locomotives.

"These windows are not openable and are fully enclosed. The window materials are made of new materials. They are very strong and can reduce noise to a great extent." Liu Tao pointed to the windows.

Although this is just a train, it involves all aspects.

Otherwise, Japan and France would not be the only ones in the world currently.

"According to my calculations, if you place a coin on the edge of the window when the Fuxing EMU is in motion, it will almost never fall over." Liu Tao smiled lightly. Nothing could be more convincing than this.

"How is that possible?" The person in charge of Iron Boss couldn't help but exclaimed.

Liu Tao smiled and said, "Everyone can try it out later."

I took everyone to visit the entire carriage, from beginning to end.

The train lady, train police, conductor, and driving crew all followed, and everyone was deeply shocked by the "Fuxing" EMU.

Then we come to the cockpit, which is completely different from a traditional train. There are 5 display screens on the cockpit, as well as some buttons and operating levers.

Very neat, beautiful, and full of modern technology.

This makes driving a train very convenient.

"This button is the control button for all hatches. Press the button down and it will turn red. All hatches will be closed at the same time. Press the button again and it will turn green. All hatches will be closed. Of course, during operation, unless there are special circumstances, the hatches will be open. , the closing is handed over to the driver in each carriage, and then reported to the cockpit. "Liu Tao pointed to a button, and these buttons have their own functions.

Subsequently, each car lady and car policeman began to perform their duties.

The car lady pressed the button to close the hatches one by one.

Liu Tao personally demonstrated how to drive. No one else knew how to drive except him.

Even the carefully selected drivers and commanders here have never driven.

Liu Tao started the Fuxing EMU and then explained everything.

The Fuxing EMU started running, and the speed was getting faster and faster. The speed of the EMU was displayed on the display screen at any time.

Everyone could hardly hear the clanging sound of traditional trains.

Liu Tao drove the Fuxing EMU very easily.

Many buttons are not used normally, and they are only used in some special situations.

Normal people can drive the Fuxing EMU with a little understanding.

Next, he will spend some time to train two trains so that these two trains can carry out a series of tests on the Fuxing EMU.

After all, he can't invest too much time and energy in this.

He still has more things to do.

"Look, the speed has reached 100 kilometers per hour." Someone exclaimed. Not long after it was started, the Fuxing EMU had reached 100 kilometers per hour without anyone noticing.

It's not that there are no Chinese trains that can reach a speed of 100 kilometers per hour. As early as not long after the founding of the People's Republic of China, the Jiefang steam locomotive developed in 1952 reached a speed of 80 kilometers per hour, and the 'Forward' steam locomotive developed in 1956 also reached a speed of 80 kilometers per hour. In 1957, the 'Construction' steam locomotive manufactured by Dalian Locomotive and Rolling Stock Works reached a speed of 85 kilometers per hour, and the 'Julong' diesel locomotive developed in 1958 successfully broke through 100 kilometers per hour.

The speed of the "Dongfanghong" type 1 diesel locomotive and the Dongfeng type 1 diesel locomotive reached 120 kilometers per hour.

But no locomotive can reach a speed of 100 kilometers per hour as fast as the 'Fuxing' EMU.

Everyone has no feeling at all.
