The Boss of the Yan Family in Siheyuan

Chapter 414 Laying out the Maglev Train

In the days that followed, Yan Jiecheng would meet with leadership experts from each school every day.

Everyone is actually here to explore the bottom line and see if the ministry really wants to develop magnetic levitation technology.

Yan Jiecheng gave everyone reassurance. If there is a big breakthrough in technology, the ministry will naturally adopt it and just let them put it aside.

Yan Jiecheng also has some understanding of the magnetic levitation technology of later generations. The reason why it has not been widely promoted in later generations is mainly because the cost is too high.

The cost of this maglev line is four to five times higher than that of ordinary high-speed rail.

Therefore, it can only be studied as a technology accumulation.

On the 11th, a seminar on maglev train technology research was officially held in the lecture hall of the Academic Conference of the Academy of Railway Sciences.

Not only did Yan Jiecheng and Lao Liu attend the meeting, but leaders from the Science and Technology Commission, the Faculty of Education and other relevant departments also attended the meeting.

A total of more than 300 people attended this meeting, which was considered a very high level.

In addition to the heads of various universities and research institutes, those sitting below are top experts in the industry.

Yan Jiecheng personally presided over this meeting.

At the beginning of the meeting, Yan Jiecheng welcomed the leaders. Then he briefly introduced the current research progress of maglev train technology in various countries around the world.

These materials were collected and compiled by the Academy of Railway Sciences during this period.

Then Yan Jiecheng talked about some of the advantages of maglev trains and possible future development directions.

Finally, Yan Jiecheng announced to everyone: "Comrades, because the maglev train has the advantages of high speed, low consumption, environmental protection, safety, etc., it has a very bright future.

Therefore, our country must also lay out research on this technology.

My recent research found that the theoretical speed of this maglev train is 400 to 500 kilometers per hour, and the superconducting maglev train can reach 500 to 600 kilometers per hour.

Its high speed makes it superior to flying for travel distances between 1000 and 1500 kilometers.

Because it has no wheels, no friction and other factors, it consumes 50% less power than our current most advanced high-speed trains.

在500公里/小时速度下，每座位/公里的能耗仅为飞机的1/3至1/2，比汽车也少耗能38%。

What's more, maglev trains do not rub against the track during operation and emit less noise.

Therefore, this technology is very important to our country’s railway transportation.

This is also an important reason why the ministry has called everyone here this time. We cannot lag behind others in the layout of this cutting-edge technology.

Of course, in order to ensure the smooth progress of the research work.

The ministry has dedicated research and development funds, no less than 1.3 million per year. "

When Yan Jiecheng said this, he saw that the leaders of various schools in the audience looked eager.

Then he said seriously: "Of course, this fund must be earmarked for special use. If there is no progress after taking the money, don't think about applying for it the next year.

The specific application methods for this funding will be issued to each of your institutions by our Academy of Railway Sciences. "

Next, everyone began to discuss the maglev train technology.

Maglev trains are mainly composed of three major parts: suspension system, propulsion system and guidance system.

Although it is possible to use propulsion systems that have nothing to do with magnetism, it is felt that all three functions should be completed using magnetism.

Lao Liu on the side did not understand technology. Seeing everyone discussing in groups, he asked Yan Jiecheng with some curiosity: "Comrade Jiecheng, are there any different ways of levitation on this train?"

He was really curious, and this so-called magnetic levitation really subverted his knowledge.

This train can actually levitate.

Thinking about it is like dreaming.

Yan Jiecheng saw that some of the leaders present looked confused, so he explained with a smile: "This maglev generally has three basic principles.

The first principle is that when the magnetic field near a metal changes, the electrons in the metal move and create an electric current.

The second principle is the magnetic effect of current.

When electric current flows in a wire or piece of metal, a magnetic field is created.

The energized coil becomes a magnet.

The third principle of magnetic levitation is that magnets interact with each other, with like polarities repelling each other and opposite polarities attracting each other.

The maglev train we are talking about is developed using these three basic principles.

At present, the general research and development ideas in the world are the normal conduction magnetic attraction type and the superconducting magnetic repulsion type.

The so-called normally conductive magnetic suction type uses normally conductive electromagnets installed on the bogies on both sides of the vehicle and magnets laid on the line guide rails. The attraction generated under the action of the magnetic field makes the vehicle float.

The gap between the vehicle and the rail surface is inversely proportional to the attraction force.

This suspension method does not require a special landing support device and auxiliary landing wheels, and the requirements for the control system can also be slightly lower.

There is also a superconducting magnetic repulsion type, which installs superconducting magnets on the bottom of the vehicle and lays a series of ring coils on both sides of the track.

When the train is running, current is passed through the coils on the train to generate a strong magnetic field.

The coil on the ground is tangential to the magnetic field of the superconducting magnet on the vehicle, and the two magnetic fields produce a repulsive force.

When the repulsive force is greater than the weight of the vehicle, the vehicle floats.

Therefore, this superconducting magnetic repulsion type uses the relative motion between the superconducting magnet placed on the vehicle and the passive coil laid on the track to generate a levitation force to lift the vehicle body. "

After Yan Jiecheng's introduction, several people nodded, as if they really understood.

However, this principle can generally be understood by people who have studied simple physics.

Except for Lao Liu, everyone here is a senior intellectual and can understand.

The experts in the audience were discussing the guidance method, propulsion method, train kinetic energy and other aspects.

Throughout the morning, the meeting reviewed some technologies for maglev trains.

After eating something simple at noon, the meeting started immediately.

In the afternoon, everyone had some discussions on suspension methods, guidance methods, propulsion methods, train kinetic energy, tracks, vehicles, traction, operation control, etc.

Today's meeting didn't end until seven o'clock in the evening.

Except for Yan Jiecheng, these leaders all returned home. The leaders and experts who came to the meeting basically stayed in the guest house of the Academy of Railway Sciences.

So these people continued the discussion in the guest house conference room in the evening.

Anyway, there are many problems that need to be overcome, and they are not afraid of others taking away the project.

Besides, everyone is good at different things, and when talking, you can also inquire about each other, so as to avoid a collision.

After the meeting, Yan Jiecheng did not leave.

Prepare to meet with daily reporters at the office of the Academy of Railway Sciences.

He needs to reveal some information in the official media.

He specifically reported this matter to the superiors, so the propaganda department asked daily reporters to cooperate with him.

"Leader, the reporter from the daily newspaper is here, do you see it?"

As soon as Yan Jiecheng arrived at the office and took a sip of water, Zhang Tonglai asked.

Yan Jiecheng put down the water glass and said, "Invite them in."

After hearing this, Zhang Tonglai nodded and went out.

After a while, Zhang Tonglai arrived with three people.

A man in his early forties, a good-looking lesbian in her early twenties, and a young man in his early twenties carrying a camera.

As soon as the middle-aged man saw Yan Jiecheng, he quickly said: "Leader, I am Yu Wensheng from the Chinese News Agency."

Yan Jiecheng smiled, shook hands with the other party, and said, "Thank you for your hard work, Director Yu."

Then, Yu Wensheng pointed to the lesbian next to her and said, "This is reporter Yang from the TV station, and this is Xiaonian, the cameraman."

Yan Jiecheng smiled and nodded at the two of them.

He was not in the habit of shaking hands with beautiful women.

This kind of intelligence, as well as a natural charm, seems to be the best at first glance, but it cannot be used to test yourself.

A big cadre like myself cannot stand such a test.

After a few people sat down, Zhang Tonglai poured tea.

The three of them quickly thanked Director Zhang. Then, Yan Jiecheng said: "This time we need your cooperation to send a signal to the outside world."

Seeing the calm expressions on the three people's faces, Yan Jiecheng knew that the propaganda outlet had already explained to them.

So he continued: "The main thing is a report on the seminar we held in the past few days on the development of maglev trains.

Mainly to give these three pieces of information to the outside world.

The first is that our country has begun the research and development of maglev trains.

The second is that I, the chief engineer, believe that testing suspended trains is the future development direction of high-speed rail.

The third is that we are dissatisfied with the existing high-speed rail technology, especially Alstom's technology. "

After Yan Jiecheng finished speaking, Zhang Tonglai quickly handed some information to Yu Wensheng.

Then he said: "Director Yu, these are some videos of our meetings. They are all non-confidential content. You may be able to use them."

Zhang Tonglai handed two more documents to Yu Wensheng and Reporter Yang, and said, "You can take a look at some of the materials we compiled on this matter."

Afterwards, several people discussed it and conducted some interviews with Yan Jiecheng.

It mainly revolves around the issue Yan Jiecheng mentioned before.

The work didn't end until an hour later.

Lu Zhiping, who was waiting in the driver's lounge, received the notice from Zhang Tonglai, so he quickly went out to start the car and drove to the office building to wait.

After this matter was arranged, Yan Jiecheng was about to get off work, so he and Zhang Tonglai sent the three people out.

When he got downstairs, Yan Jiecheng saw a car with a TV station logo spray-painted on the side, and knew it belonged to the three of them.

Yu Wensheng and the other three were frightened when they saw a leader like Yan Jiecheng sending them and others downstairs.

Yan Jiecheng said with a smile: "It's okay, I'm off work too, so I'll go downstairs with you."

Yan Jiecheng glanced at the other party's car and then said, "Okay, it's getting late, so you should go back early."

When Yu Wensheng saw that Yan Jiecheng's special car had parked under the office building, he quickly said: "Boss, you go first, we are not in a hurry."

As for how Yu Wensheng knew this was Yan Jiecheng's special car, it shouldn't be too simple.

After all, ordinary people are not qualified to sit on the big red flag these days.

Besides, no one except the top driver would dare to park the car directly in the middle of the office building.

Yan Jiecheng saw that they were polite and knew what these people were worried about.

Then he smiled and said, "Okay, I'll leave first, and you can rest early."

After Yan Jiecheng finished speaking, the driver Lu Zhiping quickly opened the door.

After Yan Jiecheng was done, Zhang Tonglai specially told Lu Zhiping: "Brother Lu, drive more steadily. The leader did not rest today and may squint for a while on the road."

Lu Zhiping nodded quickly after hearing this, indicating that he understood.

After Yan Jiecheng left, Yu Wensheng greeted Zhang Tonglai, and the three of them got into the car and left.

On the way, reporter Yang looked at Yu Wensheng and said, "Director Yu, this leader looks so young. He looks a few years older than me."

Yu Wensheng glanced at the other party and said in a deep voice: "Xiao Yang, this leader is not an ordinary person.

Considering that we have known each other for many years, let me remind you.

You'd better put away those little thoughts of yours, otherwise you won't know how you will die. "

Yu Wensheng also felt a little disdainful. He had known this reporter Yang for six or seven years.

Although there is nothing to say about my working ability, I always want to reach a higher level.

Now I am in my twenties and have not yet started a family. I just want to find a golden son-in-law.

This matter depends on the person. Is Yan Gong something she can think about?

Yu Wensheng was also born in a compound and knew the background of Yan Jiecheng's family very clearly.

If someone dared to break Hui Chang Kexin's marriage, he couldn't imagine what would happen.

Reporter Yang couldn't help but be stunned when he heard Yu Wensheng's warning.

She knew more or less about her leader's background.

Seeing that the other party was so cautious, he was also a little curious.

Yu Wensheng saw her expression, and he didn't know what the other person was thinking, so he said directly: "Don't be curious, you can't talk about this matter, and I don't dare to talk about it, you understand."

After hearing this, Reporter Yang knew that this was something that could not be done, so he nodded and stopped talking.

During the next few days of meetings, many issues were discussed.

After all, the research and development of maglev trains covers almost all industrial categories.

Materials such as special steel, wires and cables.

Integrated gate commutated thyristors, integrated circuit boards and other components.

High-power converters, safety computers, controllers, suspension racks and other component levels.

The entire system-wide industrial chain of operation control, wireless communications and other equipment also needs to be slowly resolved.

The independent development of key vehicle components such as vehicle bodies, sensors, and electromagnets, as well as the entire vehicle, requires the cooperation of universities and research institutes across the country.

The development of traction power supply system prototypes such as traction transformer and current converter, control, switch station, long stator linear motor, etc. requires the participation of the academic department.

In addition, the development of complete sets of engineering equipment for operation and control communications such as central subsystems, zone control, and vehicle-to-ground communications requires the joint efforts of various computer institutes across the country.

The research institutions in the ministry are enough for all line tracks with different structures, such as new track beams, switches, and functional parts.

As the discussion deepened, we discovered that there were more things that needed to be studied from scratch.

The week-long meeting finally ended, and the heads of these units went back immediately.

I started to prepare to apply for project approval. After all, the ministry only has more than 100 million yuan in funding for this job a year. So many units are watching, and if it is slow, I may not even be able to drink the soup.

The news that Yan Jiecheng wanted has been broadcast in newspapers and on TV.

Within a few days, the work on receiving Alstom's technology was progressing smoothly.

Yan Jiecheng did not expect that he would even send a special letter to Xiaori, hoping to cooperate in the field of maglev trains.

To put it simply, they provide funding for China's research, and both parties share the research results.

Yan Jiecheng was very confused about this matter.

It can only be said that it is too difficult.

On the one hand, Yan Jiecheng wanted other people's funds, but on the other hand, he didn't want to share the results.

In this matter, Yan Jiecheng knew that he had to make a choice.

Cooperation is not impossible, but the details need to be communicated carefully.

You must know that the maglev train technology that has dominated today's small days is one of the best in the world.

If China cooperates with it, it is very likely that the domestic technical route will follow the footsteps of Xiaotian, and it will never escape the technical trap of Xiaotian.

This kind of thing is what Yan Jiecheng is most worried about.

You know, the little ones these days are really strong.

This year their economy surpassed Maozi and became the second largest economic power after Yingjiang.

The Plaza Accord has not yet been signed, the yen has not appreciated significantly, and Xiaoli products are sold all over the world.

The self-esteem of the entire small nation was greatly satisfied.

The society is also very stable, with abundant supplies, and the environment has returned to cleanliness after excessive pollution.

It can be said to be the golden age of small life.

Therefore, facing such a small day, Yan Jiecheng had to be cautious.

Yan Jiecheng had no choice but to decline the matter.

In recent years, the country with which the country has had the most international dealings has actually been a small country.

Everyone is wary of dealing with Xiaoli.

After all, who knows that these countries have basically no integrity and their moral bottom line is almost zero.

So I'm afraid of being cheated.
