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 bother, but stood quietly behind him, listening to their discussion.

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

"We had to make sure that it was in a very narrow operating area, and still had to keep the basic functions intact, safe and reliable, and at the same time efficient."

"It's not a simple request, and it's no wonder that there is no one in the country right now."

"You look at the sketch I drew, to achieve the functionality he said, it is impossible to just change the chassis as you said."

"The whole machine had to be rearranged, including the cab, the engine compartment, the transmission, and so on."

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

It was Qiao Mai who spoke, and she had a simple drawing drawn with a pencil in her hand, Chen Nian glanced over and found that this simple map was actually very similar to the all-terrain excavators he had seen in later generations.

Of course, there is an essential difference between "concept maps" and "drawings", and it does not mean that with simple drawings, things can be made.

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

It's as if you had drawn the drawings of the F-22 yourself

And Wang Jiancheng, who was sitting next to Qiao Mai, said while looking at the drawings:

"You're right, but there should be a way to fix it, right?"

"For example, the problem of the hydraulic system mentioned by you, 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 him categorically, and then explained:

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

"To put it bluntly, if you want to use this excavator in the mountains, how can you make it firmly nailed to the rock wall and nailed to the mountain road."

"Could it be that you want to make a rope, and every time you move, let people manually smash the positioning pile into it?"

"So, it's important to fix the system."

"According to the current universal design, we either use positioning piles or hook jaw positioning modules, no matter which of the two, they are designed to design a huge number of hydraulic systems."

"Even every bending joint requires a set of independent hydraulic equipment, and the operating 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.

He then turned his attention to another key word marked on the paper, drivetrain.

"What about the drivetrain? Is this difficult? ”

I don't know how to say it. If we have high requirements, then 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 hydraulic system structure of hydraulic presses, save energy and improve performance."

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

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

"As you just said, our goal is to reduce the volume to less than 4X4, which belongs to the mini excavator, and it's difficult anyway."

"I don't have to reduce the volume so much, I mainly consider the small construction area, if there is another way to overcome this problem, then the volume is not uncompromising."

"Isn't the problem that I can't think of any other way?"

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

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

Although the two people in front of them have a certain correlation in their backgrounds, none of them have been seriously exposed to excavators.

It is really amazing that with this limited information, so many conclusions can be drawn 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 all-terrain excavator they need.

You have to do it yourself!

Chen Nian patted Wang Jiancheng's shoulder, and the latter looked back, immediately gave up his seat, and motioned for Chen Nian to sit down.

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

Chen Nian shook his head and replied:

"No, I've been listening to it for a while, and I basically understand it."

"So now, the difficulties you have sorted out are mainly concentrated in the positioning system, hydraulics and transmission, and electronic control, right?"

Qiao Mai nodded, rubbing his head and said:

"To be honest, we're doing our best to discuss this now, and it's still very difficult to achieve anything."

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

"What if it can be done?"

Chen Nian asked.

"Huh? Can you do it? How? ”

Qiao Mai subconsciously repeated Chen Nian's words, with some doubt 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's eyes with some expectation.

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

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

Qiao Mai is obviously aware of this, too.

So he wanted to know what 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 concern is that if I do start this project, if it doesn't come to fruition, won't it be a dash to other people's hopes?"

"After all, it's not a scientific project, it's one."

"Firefighting project."

Chen Nian added.

"That's right, it's a firefighting project. I'm afraid we don't have enough power to put out the fire. ”

"Give it a try."

Chen Nian couldn't help but make a conclusion, and then, he took the simple drawing drawn by Qiao Mai and said:

"Let's start with the basics, let's talk about the powertrain first."

For the next few hours, Jomai felt as if she had entered a whole new realm.

She never imagined that the process of development and design could be so simple.

In the vast majority of cases, a question has just been thrown, Chen Nian has already given a key hint, and then he uses his existing knowledge to quickly improve it.

Wang Jiancheng on the side was not idle, he summarized and recorded the discussion between the two, and at the same time 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 the discussion is frightening.

Even, before the library closed, they had already solved the problem with the two main systems in this excavator.

Of course, the way to solve the problem is not to say that it has actually been made, or that there are drawings and can be put into production, but that the correct, standard and absolutely usable thinking has been established.

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

Is this the real way to open a project?

She could clearly feel that if she was a driver, every previous project was to move forward in the dark on the winding mountain road where she couldn't see her fingers.

His own limited knowledge system is the headlights that guide the way, and even if there is, it can only illuminate a narrow area ahead.

But Chen Nian's existence is like a reflective road sign 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 its own "car".

In other words, Chen Nian has never been guided in a way that surpasses his own knowledge system.

What kind of monster is this?

Even with the mentor, I have never experienced this myself.

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

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

She looked at the young man of the same age as herself in front of her with blazing eyes, and she didn't know what to say for a while.

However, Wang Jiancheng, the first time he saw the results, he had already begun to tout that he didn't want money.

"Damn. Senior, is there anything you won't know? ”

"Even if you do airplanes, you can do AI, and now you can even do excavators?"

"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 can the Sanyang factory understand that it will be handed over to the mechanical and electrical institute first, let them come up with perfect design drawings, 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 really okay to let XCMG come."

"Anyway, let's give them a try"

Instead of directly handing over the technology and design to XCMG, but letting the mechanical and electrical institute output it to Sanyang Factory, the reason why this decision was made, in fact, Chen Nian also had his own considerations.

That is, if all technologies are enriched 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 fall in pieces because of the so-called "technological suffocation".

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

Therefore, the "technology sinking" of non-critical modules is the inevitable path.

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

With their plans for the next step decided, the three of them left the library together and had a late-night snack at the Late Night Snack Exploration outside the school.

Throughout the night, Qiao Mai's eyes never left Chen Nian, and he even saw that Chen Nian's heart was a little hairy.

But from start to finish, the conversation between the two did not deviate from what they were doing.

That is, excavators.

From the perspective of passers-by, this is indeed an extremely strange phenomenon.

Two young boys and girls in the prime of their youth sit together, the girl's eyes are obviously full of affection and desire, but they are discussing various mechanical principles that people can't understand

Is this some kind of new era ambiguous way?

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

That is, it was not himself who made Qiao Mai affectionate, but the excavator

When she looked at herself, she probably saw an all-terrain excavator with strong and powerful arms, a wide and far-reaching digging bucket, four unswerving positioning axes, and two indomitable tracks

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

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

At this time, due to the full launch of the project to move mountains, the name of the DAO has begun to become a little intimidating.

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

And Liu Maocai did not receive the news, and when he saw the two, he still showed an impatient and helpless attitude.

"You two, you really don't have to look for me, I really can't help it"

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

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

"Otherwise, this trip is one trip at a time, when do we have to toss it?"

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

Wang Qing interrupted him with a smile on his face.

"What do you mean it must work, I said it, this thing can't be solved by taking it for granted, we don't have that technology!"

"And what if you have one?"

As he spoke, Wang Limin stepped forward in a timely manner, took over and said:

"Director Liu, you haven't received a notice yet, but I estimate that soon, the SASAC will contact you."

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

"At the same time, the corresponding technical documentation has been prepared and will be issued after the final confirmation."

"You don't have to worry about technical problems, someone has helped you solve -—— your factory, you just need to use the technology well."

Liu Maocai opened his mouth wide in astonishment.

He could understand every word of Wang Limin, but when it was connected, he was completely confused.

What's the situation?

The Mountain Moving Project?

The project that was on the evening news and took up a full two minutes?

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

Moreover, there are people who provide technology

How big a pie does this have to be on your head?

His gaze turned to Wang Qing.

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

At this time, Wang Qing's thoughts were exactly the same as his, and he also felt that his cousin, Wang Jiancheng, was a little mysterious.

Of course, far away in the Western University of Technology, Wang Jiancheng's attitude towards Chen Nian is the same
