Spark

Chen Nian made an appointment with Wang Jiancheng to meet in the discussion area of ​​the library, but when he arrived, he found that Wang Jiancheng was already discussing with Qiao Mai.

He didn't go to disturb, but stood quietly behind, listening to their discussion.

".So the excavator he wants, the most important thing is the all-terrain capability, and at the same time, the volume should not be too large."

"We must ensure that it still maintains basic functional integrity, safety and reliability within an extremely narrow operating range, while taking into account efficiency."

"This is not a simple requirement. No wonder there are none in China now."

"Look at the sketch I drew. To achieve the functionality he said, it is impossible to just change the chassis like you said."

"The whole machine is going to be reconfigured, including the cab, the engine bay, the transmission and so on and so forth."

"The core technical difficulties are not only hydraulic pressure and transmission, but also system engineering design."

It was Qiao Mai who spoke, and beside her was a sketch drawn with a pencil. Chen Nian glanced over it, and found that the sketch was actually very similar to those all-terrain excavators he had seen in later generations.

Of course, there is an essential difference between "concept drawings" and "drawings". It doesn't mean that things can be made with sketches.

But even so, Qiao Mai has fully demonstrated her strength.

It's as if I drew the blueprint of F-22.

Wang Jiancheng, who was sitting next to Qiao Mai, looked at the blueprint and said:

"You're right, but there should be a solution, right?"

"For example, the hydraulic system problem you mentioned, in fact, the complexity of the hydraulic system design of the all-terrain engine has not increased much."

"It's gone up a lot!"

Qiao Mai interrupted his words decisively, and then explained:

"You don't think it's going up much, that's because I didn't mark the hydraulics needed for the positioning system."

"To put it bluntly, if your excavator wants to be used on mountainous terrain, how can it be firmly nailed to the rock wall and the mountain road is the problem."

"Could it be possible that you want to make a rope, and every time you move, someone manually smashes the positioning stake in?"

"So, fixing the system is important."

"According to the current general design, we either use positioning piles or claw-type positioning modules. No matter which of the two are designed, a huge amount of hydraulic system design is involved."

"Even every bending joint requires a set of independent hydraulic equipment. The operation logic and performance requirements of each set of equipment are different. How can it be so simple?"

Hearing Qiao Mai's words, Wang Jiancheng sighed slightly disappointed.

Then, he turned his attention to another keyword marked on the paper, the transmission system.

"What about the transmission system? Is this difficult?"

". I don't know how to say it. If we have high requirements, we need to use high-power AC servo motors and apply them to hydraulic presses."

"The purpose of this is to replace the structure of ordinary induction asynchronous motors, simplify the structure of the hydraulic system of the hydraulic press, save energy and improve performance."

"This is the basis for the miniaturization of this all-terrain excavator."

"Of course, we can also maintain the original asynchronous motor design, but in that case, we must start from other aspects to reduce the size of the entire excavator."

"As you said just now, our goal is to reduce the volume to less than 4X4, which belongs to miniature excavators. Anyway, it is very difficult."

"It is not necessary to reduce the volume so much. My main consideration is that the construction area is small. If there are other ways to overcome this problem, then the volume is not uncompromising."

"Isn't the problem just that I can't think of other ways?"

Chen Nian listened to their discussion with great interest, and secretly sighed in his heart:

Sure enough, the world of Xueba is different from that of most ordinary people.

Although the two people in front of them had a certain background, none of them had ever been in contact with an excavator.

Just relying on this limited information, it is really amazing to be able to draw so many conclusions that can be said to be completely correct

However, relying on the two of them, it is still a bit too whimsical to design the required all-terrain excavator.

You have to do it yourself!

Chen Nian patted Wang Jiancheng on the shoulder. The latter looked back and immediately gave up his seat, motioning for Chen Nian to sit down.

"Senior, we haven't discussed it for long, do you want to tell you what happened before?"

Chen Nian shook his head and replied:

"No need, I just listened to it for a while, and I basically understand it."

"So now, the difficulties you sort out are mainly concentrated in the three parts of the positioning system, hydraulic pressure and transmission, and electronic control, right?"

Qiao Mai nodded, rubbing his head while saying:

"To be honest, we are doing our best to discuss this now. It is still very difficult to achieve any results."

"After all, we can't solve the servo motor problem."

"Then what if it can be done?"

Chen Nian asked.

"Ah? Can it be done? How can it be done?"

Qiao Mai subconsciously repeated Chen Nian's words, with some suspicion in his tone.

".I'm just giving you an example. Have you ever thought about solving this problem yourself?"

Chen Nian looked at Qiao Mai expectantly.

In fact, from his point of view, for Qiao Mai, to participate in the main work of the Yishan project but only be a marginal handyman, it is better to be fully responsible for a small equipment design as he is now.

Although it may not be so amazing in scale and not so conspicuous in personal resume, it will definitely not be worse than participating in the main work in terms of training one's own ability or the "significance" of the project itself.

Qiao Mai is obviously aware of this.

So he wanted to know how Qiao Mai would choose.

After hesitating for a moment, Qiao Mai replied:

"I want to solve it, but the problem is, I don't know if I'm capable enough."

"My main worry is that if I really start this project, if there is no result in the end, won't it make others' hopes come to nothing?"

"After all, this is not a scientific research project, this is one."

"Firefighting project."

Chen Nian added.

"That's right, it's the firefighting project. I'm afraid that we are not capable enough to put out the fire."

"Try it."

Chen Nian couldn't help but come to a conclusion. Afterwards, he took the sketch drawn by Qiao Mai and said:

"Then let's start with the most basic part, let's talk about the power system first."

In the next few hours, Qiao Mai felt as if he had entered a new realm.

She never thought that the process of R\u0026D and design could be so simple.

In most cases, Chen Nian has already given a key hint just after a question is asked, and then, he uses his existing knowledge to quickly improve it.

And Wang Jiancheng on the side was not idle either. While summarizing and recording the discussions between the two, he put forward a few corrective suggestions from time to time, erasing the contradictions or conflicts in the design he proposed one by one.

Under such a division of labor, the efficiency of discussions is frighteningly high.

Even, before the library closed, they had fixed the problems with two major systems in this excavator.

——

Of course, the way to solve the problem does not mean that it is actually manufactured, or that there are blueprints, and that it can be put into production, but that a correct, standard and absolutely usable idea has been established.

Even if there is a correction later, the magnitude will not be too great!

Is this really the correct way to open a project?

She could clearly feel that if she was a driver, every previous project was to advance in the dark on the winding mountain road where the fingers could not be reached.

My own limited knowledge system is the car lights that guide the way. Even if I have them, they can only illuminate a narrow area in front of me.

But the existence of Chen Nian is like the reflective road signs on both sides of the highway, directly outlining the entire road.

——

And more importantly, the light reflected by the road sign is not the light emitted by itself, but from the lights of his own "car".

In other words, Chen Nian has never once guided in a way beyond his own knowledge system.

What kind of monster is this.

Even with the mentor, I have never had such an experience.

Being able to do this step can only explain one problem, that is:

Chen Nian's overall knowledge structure, including experience, has already achieved a crushing lead on himself.

She looked at the young man of the same age as her with piercing eyes, and for a moment she didn't know what to say.

On the contrary, Wang Jiancheng, as soon as he saw the results, had already started his free-for-nothing bragging.

"Fuck. Senior, is there anything else you don't know?"

"It's okay to be an airplane, you can do AI, and now you can even do an excavator?"

"What does my mother say now, can we take this directly to Sanyang Factory?"

Hearing his words, Chen Nian shook his head and replied:

"How could the Sanyang factory understand that it should be handed over to the mechanical and electrical department first, and let them come up with a complete design drawing, and then hand it over to the machinery factory below for processing."

"I'm not sure if your Sanyang factory has enough processing capacity, but it's okay to let XCMG come if it doesn't work."

"Anyway, give them a try first."

Instead of directly handing over the technology and design to XCMG, the electromechanical institute exported it to Sanyang Factory. Chen Nian actually had his own considerations for making this decision.

That is, if all technologies are concentrated in large enterprises like XCMG, the vitality of the sinking market will be seriously damaged.

It is even possible that those township enterprises and small private enterprises will collapse one by one due to the so-called "technical suffocation".

Especially under the premise that I have already determined to detonate the financial crisis in advance.

Therefore, the "technical sinking" of non-key modules is an inevitable path.

Even if they don't do that well, as long as they do, there is hope.

After confirming the follow-up plan, the three of them left the library together and went to the night snack exploration outside the school to have a late night snack.

Throughout the whole night, Qiao Mai never took his eyes off Chen Nian, and Chen Nian even felt a little scared when he saw it.

But throughout, the conversation between the two never strayed from what they were doing.

Namely, excavators.

From the perspective of passers-by, this is indeed a very strange phenomenon.

Two young boys and girls in their prime are sitting together, the girls' eyes are obviously full of affection, and they are eager to talk, but they are discussing various mechanical principles that people can't understand

Is this an ambiguous way of the new era?

But if you look at it from the perspective of a person who has personally experienced it—such as Chen Nian's perspective, he is actually very clear about one thing.

That is, it was not himself, but the excavator that made Qiao Mai feel affectionate.

When she looked at herself, she might be seeing an all-terrain excavator with a strong and powerful arm, a wide and far-reaching bucket, four firm positioning axes, and two indomitable crawlers. .

A few days later, under the comprehensive guidance of Chen Nian, Qiao Mai successfully completed the design of the first version of the all-terrain excavator.

Subsequently, her design was submitted to the Electromechanical Institute, which was optimized, archived and filed, and finally sent to the Changshun County Party Committee.

At this time, due to the full launch of the Yishan project, the name of the Civil Affairs Office has begun to become a little scary.

Therefore, as soon as the order was received, the county party committee assigned Wang Limin and Wang Qing to Sanyang Machinery Factory.

However, Liu Maocai did not receive the news. When he saw the two of them, he still showed an attitude of impatience and helplessness.

"Two, you really don't need to look for me, I really can't help it"

"If you come to me again, then I will have to go to Secretary Chen."

"Don't worry, I'm not going to sue, I just want to clarify the situation."

"Otherwise, how long will we have to toss around this time?"

"Director Liu, you will definitely be able to do it this time."

Wang Qing interrupted him with a smile all over his face.

"I've already said what it means to be able to do it. You can't take it for granted. We don't have that technology!"

"And what if you have?"

With that said, Wang Limin stepped forward in a timely manner, took the words and said:

"Director Liu, you haven't received the notification yet, but I guess the State-owned Assets Supervision and Administration Commission will contact you soon."

"Your factory has been selected and included in the large-scale construction machinery development project of Yishan, and is responsible for the research and development of all-terrain excavators."

"At the same time, the corresponding technical documents have also been prepared and will be issued after the final confirmation is completed."

"You don't have to worry about technical problems anymore, someone has solved it for you——your factory, you just need to make good use of the technology."

Liu Maocai opened his mouth wide in surprise.

He could understand every word of Wang Limin's words, but when they were linked together, he was completely dumbfounded.

what's the situation?

Mountain moving project?

The item that made the evening news and took up two full minutes?

How could a broken state-owned machinery factory in a remote area of ​​my own be suddenly selected?

Moreover, there are still people who provide technology.

How big of a pie must it be to hit him on the head?

His gaze turned to Wang Qing.

At this moment, he suddenly felt that this man was a bit mysterious.

At this time, Wang Qing had exactly the same thoughts as him, and he also felt that his cousin, Wang Jiancheng, was somewhat mysterious.

——

Of course, Wang Jiancheng's attitude towards Chen Nian is also the same in Xigong University.
