Chapter 165: Which one is better? (4k)
Lou Xiao'e hung on Gao Zhendong's neck, nodding her head repeatedly, and Gao Zhendong followed her head little by little: "Yes, yes, yes, you do your thing, and I will learn from mine, hehe. "
Mother Lou looked at her angrily and funny: "Don't be ashamed."
Lou Xiao'e curled her mouth, with a proud look on her face, and then giggled.
Father Lou and mother Lou also laughed when they saw her look.
The Lou family could not be more satisfied with Gao Zhendong. He has good conditions in all aspects, and his personality and behavior are also very good. There is nothing good to say about Lou Xiaoe and the Lou family.
The only thing is that it is a bit pitiful, being alone.
Put aside this sad thing, this is not half a son-in-law, this is a whole son-in-law.
After the matter was discussed, Gao Zhendong and Lou Xiaoe were tired for a while and left Lou's house.
Lou Xiao'e chased him out, stood up on tiptoes and held Gao Zhendong's face, stamped him with a few big seals, and then ran home giggling.
The next day, Gao Zhendong, who was in high spirits during happy events, ran to the confidential room and sent out a confidential document.
As for the wedding, Gao Zhendong kept his word and left it to the Lou family to handle it.
Part of the equipment has already been assembled and debugged in the single crystal furnace laboratory, such as the power supply and part of the furnace body.
Some electric actuating mechanisms are also arriving one after another, but this part cannot be assembled and debugged until the main furnace body is installed.
Yu Yuncheng, another silicon monocrystal boss in the group, is also working very hard. There are many conditions here that he wants but does not have, and there is also a lot of new knowledge and theory. For him Also a huge improvement.
The atmosphere in the entire scientific research group is very good. As long as the progress is extremely smooth, the prospects are bright, and everyone is looking forward to the project, you can't find a few projects where the atmosphere is not good.
Now Gao Zhendong is basically responsible for the principles, routes, initial design, and the detailed design of some of the subsystems of his major. Of course, someone will do the other things properly in case he is stumped. , will come to Gao Zhendong to solve the problem.
This greatly liberated Gao Zhendong himself, and he could do other things.
In fact, this situation is very common. It is the operating mode of a normal and healthy scientific research team. From the top to the bottom, each performs his or her duties and exerts his or her own strength for one direction.
Otherwise, in his previous life, Gao Zhendong saw those scientific research experts, how could they produce so many results? Even though they may not have been in the project team for a long time and did not do many things personally, their importance may be Much more than working in the laboratory every day.
At the Grassland Tractor Factory, Mr. He quickly received confidential information from Gao Zhendong.
Confidential channels, in addition to confidentiality, are also faster than ordinary communication channels.
Mr. He opened it and saw the No. 3 Steel Rolling Plant. He was overjoyed and looked forward to the stars and the moon. This was something he had been waiting for.
This is not to say that Mr. He just relies on "waiting, relying, and asking" to do his work, but since a matter has a clear solution channel with excellent results, then wasting time and manpower to do it is obviously a waste of time and manpower. There's something wrong with the brain.
The country is still very poor, and the little resources are not wasted like this.
Mr. He opened the material excitedly and read it carefully.
Although he had already seen the catalog of this book before, when he saw the actual content, he was still excited and a little shocked.
So complete!
I quickly flipped through this manuscript. The whole book starts with the basic indicators and requirements. These indicators and requirements alone are what Mr. He and others did not consider completely when they considered artillery bi-stability before. .
Director Gao is a great talent!
Waiting for the theoretical analysis of the disturbance chain later, and then determining the model, parameters, identification, analysis, optimization, etc. of the drive chain based on the disturbance chain, this made Mr. He feel a little overwhelmed.
It’s not that I can’t accept it, but that Director Gao really gave too much.
The whole book is full of various theories and formulas, which made Mr. He realize that don’t read the rest for now. I really can’t understand it for the time being. I’d better start with the simplest indicators and requirements. Look at it.
Fortunately, the second-generation tank has not yet been demonstrated, and the entire research and development work has plenty of time. Otherwise, it would be really fun to get the cheats but not be able to get the results because you don’t understand them.
Looking at the first part, Mr. He was already in a dilemma. Which of the three bistable systems should be used?
Hydraulic? Electro-hydraulic? Fully electric drive?
The three methods each have their own advantages and disadvantages, which made him tangled.
However, he is open-minded and rough by nature. After struggling for a while, he stopped struggling. I shook him off and let the superiors deal with it.
It’s not that he is unwilling to face the problem head on, but that this thing is related to the route of the entire system, and it really takes someone at the top to determine it.
To give a simple example, if I choose a full electric drive, will there be any problem with the power of the engine?
I choose full fluid, can the car body be arranged?
Thinking of this, Mr. He put away Gao Zhendong’s artillery system stabilization manuscript and ran directly to Mr. Luo.
"Mr. Luo, I received the bistable book from Director Gao, but there is a problem."
In the circles of the 5DL bosses of Prairie Tractor Factory, when it comes to Director Gao, then There is no one else but one: Director Gao Zhendong of the Third Rolling Mill in Beijing.
Mr. Luo raised his eyebrows: "What? Can't you solve the problem?"
"Yes! It's very possible. But there are many ways to solve the problem, and it's not easy for me to choose."
After that, he talked about the problems he encountered. After Mr. Luo listened to Mr. He's words, Question, looked at the manuscript, waved his hand, and started a meeting!
It’s not that they relied entirely on Gao Zhendong’s book without any accumulation. 5DL originally had a vertical monostable, but after seeing more possibilities in the book, it turned out that the vertical monostable The driving principle is not so fragrant.
Soon, several sub-system bosses gathered together in Mr. Luo’s office.
Knowing that this small meeting was held because of Mr. He's affairs, the boss in charge of maneuvering laughed and said: "Old He, you are very proud of the foreign aid you have received recently. You can't do it." Mr. He He laughed and said, "Yes, yes, I have too many things to choose from, so I ask for your help."
If he behaves like this in a few decades, everyone will probably start to curse, Versailles, Lao He.
When everyone arrived, Mr. He repeated his problem and finally said: "Comrades, this is the situation. My current problem is to conduct pre-research on the bi-stable system of the next generation tank. When the time comes, which one should I choose among full-liquid, electro-hydraulic and all-electric?”
When the boss in charge of maneuvering heard this, he laughed and scolded: “Damn it, I don’t know anything about full-liquid here. You don’t mind using full fluids here.”
The walking and suspension system is different from the bistable. The “three-fluid” system composed of hydropneumatic suspension, hydraulic transmission, and hydraulic control is the current walking and suspension system. The highest goal is a top-level technical problem that can only be imagined but is difficult to achieve. Even after twenty or thirty years, it has not been completely solved.
Fortunately, these "three liquids" are fundamentally the icing on the cake. Without them, several core elements of the tank can be realized.
Mr. He smiled and said: "My requirements here are low."
The boss in charge of maneuvering thought about it and started to talk about business: "To be honest, the power is not as good as my engine. It’s not a problem. If it is driven by hydraulic pressure, it still needs a power pack to provide power. No matter what system is used, the power difference is not big, it is just that the output method is different.”
Guan. He didn't say anything. This matter has little to do with his protection of this place for the time being.
The boss in charge of the car body has something to say: "If it is full fluid, it will indeed have some impact on the layout of the space inside the car. The advantage of full fluid is that the technology is simple and reliable, but it also suffers from noise, efficiency, heat dissipation, and maintenance. There are certain problems with safety and maintenance costs. It is actually a trouble in itself to leave enough space for the maintenance of the hydraulic device in the car body. ”
Speaking of this, Mr. Guan is no longer sleepy: "Another problem with full liquid is that it is easy to catch fire after battle damage, and the secondary effect is not low. Although with the help of Director Gao, there is hope for a breakthrough in the fire extinguishing and explosion suppression system. , but we can’t rely entirely on this.”
Well, others can help with fire suppression and explosion suppression, but the problem we are discussing here is that their help is a bit too thorough.
Mr. Luo thought for a while and asked Mr. He: "What are your own ideas?"
Mr. He grinned broadly: "My own idea is, of course, to develop a full electric drive, and Director Gao’s manuscript also contains a lot of design principles and schematics about all-electric drive components.”
Mr. Luo said with a smile: “Director Gao’s major is automation, and he is a little more electrical automation. It’s not surprising that the examples inside use electricity.”
The CEO of Motomobility sighed for a while: "Have I even designed an example for you? If you want me to see it, Lao He, you can just get it right in one step and develop an all-electric drive."
Mr. Guan also nodded: "Me too. This idea, all-electric drive, has no secondary effects, and it is much simpler for me to protect it. I don’t need to consider the secondary effects caused by the hydraulic drive of the bi-stable system.”
The car body is also much simpler. I think this direction is good: "If it is all-electric, the size of the motor and actuator should be much smaller, the overall layout will be much simpler, and the all-electric drive efficiency is much higher than hydraulic."
Mr. Luo Listen, everyone agrees with this, so why bother?
He turned to Mr. He: "Everyone has this opinion, and you may also be inclined to this. So what are you worried about?"
Mr. He did not hesitate: "The all-electric drive is technically difficult and has low reliability. According to my existing technical means, I can only use analog acquisition and control for the all-electric drive. But in harsh environments, the temperature drift of the analog system Problems such as serious, inherently inconsistent component performance and difficulty in acquisition and transmission will bring a lot of trouble. ”
“For example, poor accuracy in adjustment control and poor consistency between cars lead to complicated production and debugging, which is a little more complicated. The control method is difficult to realize, etc."
Hearing this, Mr. Luo was curious: "With so many problems, why does Director Gao still prefer all-electric drives in his book?"
"Because Director Gao's entire set of technical routes is easier to implement accurately using electronic control. Unlike me who rely on empirical methods to deduce and design, a considerable part of Director Gao's work is based on mathematical formulas for modeling, derivation, and design, so other The result can guide both full-hydraulic and electro-hydraulic, but it is naturally more compatible with electronic control."
After Mr. He finished speaking, he added: "To be honest, there are many things in this book that I don't know about for now. I still can’t understand it, it requires some advanced mathematics skills.”
Mr. Luo sighed: "A genius, but too genius."
Just when everyone was hesitant, Mr. Guan, who was the first to deal with Gao Zhendong, asked a question: "Lao He, Do you think Director Gao’s style will give you a technical route that you can’t implement or that is full of flaws?”
Hearing this, Mr. He’s eyes lit up, it must be Lao Guan? , he was the first to come into contact with Director Gao, and he was the most familiar with Director Gao’s style.
Mr. Luo nodded: "Yes, with Director Gao's style, he usually strives to be simple and direct, and solve problems from principles. He has never proposed a completely unrealistic way without realizing the basics. "
The boss of Mobility also echoed: "It makes sense, even if it is the power part that he is least familiar with, the idea of the power package he proposed is based on the existing technical conditions."
Mr. He thought for a while: "Actually, the entire route has been explained very clearly. It's just that my own technical ability is limited, so I feel ashamed."
Mr. Luo shook his head: "Maybe it's because , in his opinion, what you lack is not only in the category of tank gun stability, so he didn’t mention it here. In other words, he thought you knew.”
After saying this, several other people couldn’t bear it. He couldn't help but burst into laughter.
When Mr. He heard this, he thought it made sense, so he simply came to the bottom of the pot and said: "You see what I am struggling with here, let's just ask Director Gao to come over. Mr. Luo, what do you think?"
"Well, that makes sense. If possible, ask him to come over and have a look on the spot, and then give you suggestions or solutions based on the conditions you have. This is the best. Besides, it's not troublesome to bother people so much. It’s time to invite Director Gao over as a guest, haha.”
As soon as Mr. He heard this, he immediately took action: "Then I'll call him right now and ask him to come over."
Mr. Luo stopped him: "I'm afraid you can't invite him. It's not that he is too arrogant. But the important work at his hands may not stop. If you ask me, it will be difficult for Director Gao to coordinate and handle the work at hand."
"Ah, what should I do?"
< br>Mr. Luo stretched out a finger and pointed at the top of his head: "We will ask the National Defense Working Committee to coordinate the invitation for him. The National Defense Working Committee will contact the 17th Machinery Department. In this way, once the trip is made, Director Gao will not have to go and coordinate with him himself. All parties involved in his work coordinated their own time, and it also seemed that we valued him."
Everyone thought that Mr. Luo's approach was good, and the matter was decided.
The leader of the National Defense Work Committee was not surprised when he received a call for help from the Prairie Tractor Factory. He also knew Gao Zhendong's achievements and attainments in this area. After all, he had attended more than one meeting related to Gao Zhendong recently.
Not to mention the infantry fighting vehicle that he and Gao Zhendong promoted together.
"Well, your idea is good. Although Comrade Gao Zhendong is young, it's great that you can put aside your dignity and age issues and take the initiative to ask for advice. This is the attitude of seeking truth from facts to solve problems. I will do this. Process.”
