Originally, I wanted to mention my own plan, but the other person didn't ask, so Yang Fan couldn't just ask. At the invitation of Sun Baoguo, I simply sat down and listened first.

The meeting continued.

Yang Fan just sat there listening carefully, and didn't say a word, but gradually, his brows frowned slightly.

This is not right!

The technicians at Dongjiang Shipyard will focus on such as disassembling a segmented part, cutting a part, and then replacing and reinstalling the bearing mount.

This definitely won't work.

The worst of the worst.

Not only is the workload huge, but the quality is also difficult to guarantee. Especially cutting some segmented parts is completely destructive, and even if weld in the future, it will be difficult to evaluate the impact on quality.

Listen, listen, Yang Fan's brows frowned even more violently, and his originally calm face became a little serious.

He thought to himself that it must be corrected and stopped. As the chief designer of the 054 ship, no one knows better than Yang Fan. It is impossible for them to do this.

Just as he was thinking that he would directly interrupt their discussion and wait a little longer, Sun Baoguo finally noticed the change in Yang Fan's face.

He also knew something might have happened, so he immediately asked, "Chief Yang, is there anything wrong with it?"

With this question, the entire conference room became quiet, and almost everyone looked over and waited for Yang Fan to speak.

Yang Fan nodded softly, looked at everyone again, and said in a loud voice: "I heard your discussion and felt something was wrong. There were some wrong directions in your discussion, which were almost all destructive. This would have an impact on the quality of the first ship, and I don't agree."

What!

The direction is wrong!

Chief Secretary Yang disagrees!

Many technicians at Dongjiang Shipyard were heartbroken. If this didn't work, they really had no better way.

Then what should I do?

Sun Baoguo may also have this concern, "Chief Yang, if this is not the case, there may be no better plan."

Yang Fan looked at everyone again and said loudly: "I have a plan, do you want to listen?"

What!

Chief Commander Yang has a plan!

Suddenly, many people were surprised!

Especially Sun Baoguo, the surprise in his heart became even stronger. He knew Yang Fan. Since Chief Secretary Yang said this, this plan must be good and should be able to solve the problems he is currently facing.

Very good!

Sun Baoguo's face suddenly changed, from worrying and a little seriousness to relax and happy. In other words, it was originally covered with clouds, but now it is clear all of a sudden.

"Chief Yang, tell us what plan to adopt."

Yang Fan said modestly: "This is the solution I personally think of. If anything is wrong, everyone is welcome to correct me."

Still so modest.

Those who know Yang Fan think so in their hearts that Chief Teacher Yang is humble.

After looking at the blackboard placed in the corner not far away, Yang Fan said loudly: "Push the fast blackboard first."

Immediately, two young technicians stood up and quickly pushed the blackboard over and placed it directly in front of the conference room as required. Everyone could see the blackboard.

Yang Fan walked over, picked up a pen, and did not write anything on the blackboard first, but said straight to the point: "I thought about it for a long time, and I think the best solution is to add an eccentric bushing into the eccentric bearing seat."

What!

Add an eccentric set!

Many people are puzzled, especially the technicians at Donghai Station in Dongjiang Shipyard, who had proposed such a plan before, but were rejected.

Wang Bo, the technical director of Donghai Station, Dongjiang Shipyard, plucked up his courage and reminded: "Chief Yang, if you adopt this plan, the risk is very high, especially involving complex calculations."

yes!

It seems that it is simply adding an eccentric bushing, but it is not simple.

Because this bearing seat is a force-bearing component, the main shaft of the power system relies on the bearing to rotate inside and output huge power, which involves complex mechanical calculations.

Of course, Yang Fan knew this and said clearly: "That's right, it does require complex calculations, such as the matching interference between the bushing and the bearing seat, the size of the bushing, etc., all of which need to be calculated."

"I've done some calculations and now I'll calculate them again for everyone. If there is any error, anyone can point it out."

After saying that, I picked up a pen and listed the first calculation formula on the blackboard.

At this time, everyone knows why we have to bring a blackboard.

The conference room was very quiet.

Everyone's eyes were all focused on this blackboard.

While Yang Fan was speaking, he listed the calculation formulas. The complex calculation process was decomposed into several steps by Yang Fan, and the explanation was thorough and everyone could understand it.

After understanding it, I gradually admired it. Chief Manager Yang could do such a complicated calculation, as if he was easy to do.

This is amazing!

As the calculation progressed, the more and more eyes of admiration were seen. After such calculations, almost all the technicians were impressed.

The blackboard is full of writing, all of which are calculated formulas, and the entire calculation process is clear.

admire!

Some people almost promising.

The calculation was completed, and Yang Fan also finished the explanation, and he put down the pen in his hand.

At this moment, everyone was still immersed in the strong shock, and the conference room was still very quiet.

After a few seconds, Sun Baoguo spoke up to break the silence. He said with admiration: "Chief Yang, great, amazing!"

"I know you have a high level, but I didn't expect that there would be such a high level. Others think it's very complicated and there is no calculation at all. It's simply a pediatrician for you."

Yang Fan smiled modestly.

Wang Bo was first shocked, then deeply admired. He was a senior designer and knew the difficulty.

He asked himself that he was not at this level, which was also the reason why he strongly denied the plan to add bushings. After reading Chief Yang's calculations, all he had left was admiration.

After such careful and scientific calculations, there will be no problems. By adding a complete set, it is the best solution to the problem.

We can only look up to Chief Secretary Yang’s level, which is so great. Wang Bo admired him very much and thought so.

Gradually, the conference room became lively.

The technicians who came to their senses could no longer help but discuss.

"Chief Yang is awesome. Such a complicated calculation is completed like this."

"I think it's best to solve the problem in this way, saving time and effort."

"Great, the problem has finally been solved."

“…”

The technicians talked so easily and happily, and the big problem that bothered them and brought them great pressure seemed to have been solved.

Sun Baoguo also felt relaxed. Looking at the lively and noisy conference room, he smiled happily and did not stop everyone's discussion, but gave enough time.

After about two or three minutes, it felt almost done. Sun Baoguo stood up and raised his hand to press down. Gradually, the conference room became quiet again.

Everyone looked at Yang Fan and Sun Baoguo.

The plan was decided, but some places felt it was necessary to remind you again. Yang Fan said: "I have calculated the size of the bushing. You should quickly make this bushing. The matching amount of it with the bearing seat is relatively large. What kind of assembly technology do you plan to use."

There are many kinds of assembly processes like this.

Which craft is the best? Yang Fan had the answer in his mind, but he did not say it. Instead, he wanted to listen to what Dongjiang Shipyard said first.

Faced with the inquiry, the director of the Technical Department of Dongjiang Shipyard stood up and replied: "Considering the large amount of interference and to ensure quality, I think the best way to cool it with liquid nitrogen."

We all know about thermal expansion and contraction.

This processed bushing will shrink after being soaked in liquid nitrogen and cooled, and the size will become smaller. It is estimated that it can be easily placed in the bearing seat at room temperature. When the temperature of the bushing returns to room temperature, it will lock with the bearing seat, forming a very strong cooperation relationship.

In a long-term working state, the bushing and bearing seat cannot move at the position and must form a steadily coordinated. Yang Fan has calculated the amount of interference.

After hearing what the minister said, Yang Fan nodded with satisfaction, "Yes, it is the best assembly process to cool it with liquid nitrogen and then put it in the bushing. What to do next? It seems that I don't have to worry about it."

The minister said confidently: "Please rest assured Chief Teacher Yang, we will definitely do the next thing well and there will be no more problems."

Yang Fan felt relieved.

Sun Baoguo also breathed a sigh of relief.

Since the plan has been decided, the meeting will be terminated immediately, and the entire Dongjiang Shipyard will also take action. The first thing is to do is to manufacture the bushing.

Sun Baoguo invited: "It takes some time to manufacture the bushing, and it will take the afternoon to install the bushing as soon as possible. Chief Master Yang, let's go for dinner first."

When he raised his hand and looked at the time, Yang Fan was slightly surprised, "Oh, it's already noon, time passes so fast."

At the invitation of Sun Baoguo, Yang Fan and others walked out of the conference room and prepared to go to lunch. Followed by several technicians in charge of Donghai Institute, or the head of the technical department of Dongjiang Shipyard.
