Chapter 296
"This is an electric engine, currently the most advanced in the country."

While watching the installation of the engine, Sima Lili introduced the situation of the engine to Lin Feng.

In fact, the electric engine is simply an electric motor, but the power factor is much higher than that of the electric motor. In other words, it is energy-saving.

The current EMUs have long changed the traditional mode of fast trains relying on the headbands. They generally use a combination of 4 powered cars and 4 unpowered cars, so they are called "groups".

The power of an 8-car EMU can reach 5500 kilowatts, which is equivalent to the sum of the power of 55 1.6-displacement cars.

So when we take the 8-car EMU, we will consume 1.53 degrees of electricity every second, which is enough to use the headlights in your living room for more than ten hours.

The electric engine is not big, and it was installed quickly. Then there are a lot of things such as transmissions, transmissions, brakes, etc., all of which are concentrated at the bottom of the train.

After these hardwares are installed in place, it is the control system.

At this point, Lin Feng couldn't quite understand it. Anyway, looking at the large bundle of thin threads, he felt that people with trypophobia would definitely go crazy.

It took several hours to install and debug the control system. During this time, Lin Feng went to the workshop to continue producing the track, then had lunch, and found a place to take a nap.

At five o'clock in the afternoon, Sima Lili sent someone to call him, saying that it was time for a test drive.

This is definitely the fastest time ever, from start to test run.

He came to the scene enthusiastically and saw various symbols flashing on a 14-inch LCD screen in front of the console.

"Let's get started." Sima Lili's voice was a little hoarse and very calm.It's like this is not developing the world's top locomotive at all, but a tractor.

"All parts are normal and can be started."

Following the command of the commander-in-chief on site, the electric engine that was still exposed to the air made a buzzing sound, and only the frame locomotive moved forward slowly.

It wasn't until after entering the official track that Lin Feng and Sima Lili came to a large monitoring screen together.

"Speed ​​90, all parts are normal! You can continue to increase the speed!"

"Speed ​​190, normal! You can continue to speed up!"

"Speed ​​270, normal!"

"Speed ​​350, normal!"

"Speed ​​500, normal! Start to slow down and stop!"

Lin Fengzheng enjoyed watching it, but the tunnel came to an end.

10 kilometers, less than 2 minutes, the maximum speed is only 500 kilometers per hour, which is still a long way from the planned 2000 kilometers.

Sima Lili looked calm, and various data were made into reports and submitted to her.

After reading the report, she discussed with several people who looked like engineers for a while, and then left the scene with Lin Feng.

"How is it?" Lin Feng asked.

"It seems ideal at first, but just now the fastest is only 500 kilometers. We have reached this speed a few years ago. Now we have to lengthen the tunnel. In order not to waste, we decided to directly open the intercity line from Rongcheng to Fucheng. Channel. It will take two or three days, so let's take a look at the new transmission and brake structure."

Lin Feng thought he could take a few days off, but his wish was instantly dashed.

When the two came to the manufacturing workshop, Sima Lili had someone bring the computer over, and brought up some old drawings to modify on it.

Sitting on a comfortable swivel chair, Lin Feng watched her dazzledly playing with the blueprints. After she finished the simulation operation, she finally printed out a stack of blueprints and handed them to Lin Feng.

"With your material, any design becomes extremely simple." Sima Lili sighed, "To make a reducer in the past, there were too many factors to consider, from material selection to processing, production, and testing. It may take a month to get down, and if it doesn’t work, you have to start all over again, repeating the process over and over again.”

This is research and development, and Lin Feng also knows the general procedure in the process.

For an industrial product, from the proposal of the design concept to the release of the final product, there are too many things that involve various industries.It is absolutely impossible for any one person to complete everything from mechanical processing to iron and steel smelting.

But now, as Sima Lili said, with supramolecular polymer materials, everything becomes so simple.

Lin Feng quickly processed a reducer into shape. After Sima Lili's optimization, this reducer was more than half smaller than the previous one, but its strength and durability increased hundreds of times.

It was already 7 days after a series of improvements were made, and 5 carriages were produced and assembled.A total of 130 kilometers of tunnels from Rongcheng to Fucheng have been completed, and temporary lines have also been erected.

8 carriages are connected together, and various lines are also connected. The huge monitoring screen will automatically switch the signal source for real-time monitoring of the train.

As the saying goes, everything is ready and everything is ready. The atmosphere at the scene is very dignified, and hundreds of technicians keep reporting the completion of the inspection.

"Let's start." Sima Lili said.

"Everything is normal, you can start Test No. 1."

I haven't seen this new locomotive for a few days, and it already has a temporary name. It's not very beautiful, and it's probably Sima Lili who picked it up.

Lin Feng looked at the tumbling and jumping numbers on the monitor screen, and it took only 10 seconds for the speed of the train to rise from 0 to 500 km/h.

Everyone has a strong sense of acceleration when taking the subway, but the EMU does not. That is because the EMU takes a long time to accelerate.

From 10 to 0 in 500 seconds like this can only happen in the laboratory.

"Speed ​​500, everything is normal, continue to speed up!"

The commander-in-chief's voice began to get a little excited, and the current test No. 1 has surpassed the previous results.

"Speed ​​750, everything is normal, continue to speed up!"

"Speed ​​1000, everything is normal, continue to speed up!"

After more than 1000 kilometers, the voice of the commander-in-chief became more and more high-pitched, and Lin Feng's heart also lifted up.

Although for him who owns the universe mall, this level of scientific and technological achievements is already difficult to see, but it is also very pleasant to be able to witness the historical record being broken.

"Speed ​​1200, voltage reduced! Slow down immediately!"

there is a problem?

Before the commander-in-chief's order was executed, a bright spark burst out on the monitoring screen. It was the connection point between the trolley power line and the train. After a puff of green smoke, it could be seen that the trolley line had been blown.

"Go and check immediately."

Sima Lili and several engineers got together again to discuss and study the data.It seemed to them that the malfunction that made Lin Feng's heart beat just now was as common as a routine.

He felt a little disconcerted. He thought he could see a high-speed train with a speed of 2000 kilometers per hour today, but it turned out that he couldn't do it until it reached 1200 kilometers per hour.

"Power supply is the biggest problem," Sima Lili sat down with him, "There is no good solution yet."

After her superficial explanation, Lin Feng understood a little bit.

Because the speed of the train is too fast, the contact point between the power line and the train is easy to produce a tiny gap due to slight vibrations.

Even if it is 1 micron, when the train accelerates and generates a huge current, an arc may be generated, and then cause an accident.

If this problem is not solved well, electric super high-speed trains can only be a plan.
