The rise of a great power: starting with military industry

Chapter 365 The shock brought by the "Fuxing" EMU

Beijing West Railway Station.

The West Station is still under construction at this time.

There will be a total of 209 stations on the entire Beijing-Kowloon Railway, including 193 stations on the mainland and 16 stations in Hong Kong.

Almost all train stations need to be rebuilt.

Of course, having so many stations does not mean that you need to stop at all of them.

Having many stations is different from having a few stops.

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

At this time, the EMU had already stopped on the track.

Unlike the previous departure with only one locomotive, there are now two locomotives. The other locomotive was pulled to the capital separately, and then finally assembled in the capital.

"This train is so beautiful, with very smooth lines." Everyone couldn't help but exclaim in amazement.

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

At this moment, just by looking at the "Fuxing" EMU, they felt shocked.

Just one look gives them a feeling of "high-end, classy and classy".

Appearance is combat effectiveness, this is an iron rule.

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

"The aerodynamic design of this locomotive took me a lot of effort!" Liu Tao pointed at the locomotive and smiled faintly.

There are complex coupling relationships among a running rail transit vehicle.

What is a coupling relationship?

Simply put, it refers to the interaction and mutual influence between things. There are complex resistance, noise, pressure waves, micro-air pressure waves and other influences and relationships between car bodies, car bodies and bogies, car bodies and on-board equipment such as pantographs, wheelsets and tracks, and trains and line facilities. In the field of rail transit vehicles, this is called "fluid-solid coupling."

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

The running resistance of rail transit vehicles consists of two parts: friction resistance and air resistance. Friction resistance is proportional to the speed of the train, while air resistance is proportional to the square of the speed of the train. When the speed of the train increases by 3 times, the air resistance will be 9 times the original.

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

Therefore, the front of the "Fuxing" EMU is pointed like a dolphin, and the overall lines are very smooth. They are all processed by high-precision instruments in order to minimize air resistance.

With this streamlined design, the cross-section of the vehicle is as small as possible, with fewer bumps on the body.

The excellent aerodynamic design, through technical designs such as the body aspect ratio, body cross-sectional shape, body cross-sectional area, flow diversion type, and cabin inclination angle, gives the train superior technical performance in terms of surface pressure, aerodynamic drag, aerodynamic lift, intersection pressure wave, and aerodynamic noise.

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

When entering the carriage, everyone was shocked by its cleanliness and brightness.

"These seats can make people sit more comfortable, and can be adjusted downwards and rotated 360 degrees." Liu Tao demonstrated, "When the EMU arrives at the terminal, there is no need to turn around by detouring. Another locomotive can be used directly, and the seats can be adjusted to the other direction."

After hearing Liu Tao's explanation, everyone suddenly understood why this "Fuxing" EMU has two locomotives.

"These windows cannot be opened and are fully enclosed. The window materials are made of new materials and are very sturdy. They can reduce noise to a great extent." Liu Tao pointed to the window.

Even though this is just a train, it involves many aspects. Otherwise, Japan and France would not be the only countries in the world that have mastered it.

"According to my calculations, if you stand a coin on the edge of a window while the 'Fuxing' EMU is running, it will hardly fall down." Liu Tao smiled faintly. Nothing could be more convincing than this.

"How is this possible?" The person in charge of Tie Lao Da couldn't help but exclaimed.

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

He took everyone on a tour of the entire carriage, from beginning to end.

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

Then we came to the cockpit, which is completely different from that of traditional trains. There are 5 display screens on the dashboard, as well as some buttons and operating levers.

It is very neat, beautiful and full of modern technology.

This makes driving a train very convenient.

"This button is the control button for all the hatches. Press the button down and it will turn red, and all the hatches will be closed at the same time. Press the button again and it will turn green, and all the hatches will be closed. Of course, during operation, unless there are special circumstances, the opening and closing of the hatches will be left to the attendants in each carriage to operate, and then report to the cockpit." Liu Tao pointed to a button. These buttons all have their own functions.

Afterwards, each train attendant and police officer began to perform their duties.

Sister Che pressed buttons and closed the hatches one by one.

Liu Tao personally demonstrated how to drive. Apart from him, no one else knew how to drive.

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

Liu Tao started the 'Fuxing' EMU and then gave explanations one by one.

The 'Fuxing' EMU started running, its speed getting faster and faster, and the display screen shows the speed of the EMU at all times.

You can hardly hear the clanging sound of traditional trains.

Liu Tao drives the 'Fuxing' EMU with great ease.

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

Any normal person with a little knowledge can drive the "Fuxing" EMU.

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

After all, he couldn't possibly invest too much time and energy in it.

He has more to do.

"Look, the speed has reached 100 kilometers per hour." Someone exclaimed. Not long after it started, the "Fuxing" EMU had unknowingly reached a speed of 100 kilometers per hour.

华夏火车不是没有时速可以达到100公里的，早在共和国成立没多久，1952年研制的解放型蒸汽机车速度就达到了80公里/小时，1956年研制的‘前进型’蒸汽机车速度同样达到了80公里/小时。1957年大连机车车辆厂制造的‘建设型’蒸汽机车速度达到了85公里/小时，1958年研制的‘巨龙号’内燃机车速度便成功突破100公里/小时。

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

However, no locomotive can reach a speed of 100 kilometers per hour as quickly as the "Fuxing" EMU.

No one felt anything at all.
