Chapter 337
The various experts of the virtual demon cave are breaking through little by little around these difficult tasks...
At the beginning, there were more than a dozen experts and scholars in various fields, each opening the mountain gate, setting up flagpoles, recruiting troops, forming large and small research institutes, vowing to be the first to win these task rewards!
As a result, if they do not study, they will just study, and once they study, endless difficulties and obstacles will emerge, and they will be extremely depressed and almost vomit blood....
Professor Wan Shen, who has a long reputation in Xinlongguo, specializes in the development of giant machinery, and once served as one of the main scientists of the heavy and giant machinery development team such as Xinlongguo's ultra-large diameter shield machine, super-large mobile mold frame bridge machine, largest bucket wheel excavator, and largest hydraulic excavator, led the establishment of a research institute to prepare to specialize in the development of 30-meter ultra-giant wide cold rolling mill.
In his opinion, although the development of this wide cold rolling mill is difficult, but no matter how big it is, it can still be difficult to surpass the shield machine and the mobile mold frame bridge machine?
You know, the shield boring machine he participated in the development of more than 18 meters in diameter and more than 180 meters in length, which can not only realize 7,000 meters of ultra-long-distance continuous boring without tool change, but also solve the worldwide problem of "ten tunnels and nine leaks" in the working environment of ultra-large diameter shield boring machine under high water pressure, realize the modern industrial miracle of tunnel boring construction without leakage, and add a sharp weapon to the construction of high water pressure and ultra-long distance tunnel boring project in Xinlongguo!
Not to mention that oversized mobile formy bridge machine!
With the blessing of the super-large mobile mold frame bridge making machine, the bridge construction of the new dragon country has become a miracle in the history of world industry, and all kinds of bizarre and difficult bridges have been born and shocked the world!
Let's just say that the reason why the new dragon country can become an infrastructure maniac, the innovation of construction machinery, technology and means is an important prerequisite, and these scientists have made great contributions to this!
Therefore, Professor Wan Shen, who has a fruitful and brilliant resume, is fully confident in the successful development of a super giant wide cold rolling mill!
Moreover, he also has a faint unspeakable ambition, that is:
to do the best!
It is necessary to come up with a model of more than 60 meters, the kind of basic model that is only 30 meters, too dish, not interesting!
However, ideals are always plump, and reality is often a slap in the face!
Just one main engine bearing completely stumped his team!
Bearing is the most important part of mechanical equipment with rotation function, its main function is to support the rotating body of the machinery, reduce the friction coefficient during its movement, to ensure its rotation within the allowable accuracy range, according to the different friction characteristics of moving parts, bearings can be divided into rolling bearings and sliding bearings two categories.
In fact, bearings appeared very early, and the time may be beyond people's imagination!
Archaeological findings show that as early as 8,000 years ago, slow-wheel pottery appeared in China, which confirms the appearance of ceramic roulette from the side. Ceramic roulette is a tool for shaping pottery through stable rotating wooden discs, stone discs or other flat working surfaces, which is the earliest and most primitive bearing!
However, because the material used by the early ancestors to make ceramic wheels is wood, it cannot be preserved to the present, so we can only speculate that its appearance and structure should be on a wooden base, through the lubricated bearings, carrying the wooden disk at high speed.
The Book of Poetry also records the life scene of people lubricating bearings from about 1100-600 BC, simply put, it is the process of a person holding the grease produced by fat meat to continuously provide lubrication for vehicle bearings.
By the time of the Qin and Han dynasties, bearings had changed from wood to metal, and were widely used in various vehicles, city gates, suspension bridges, or other rotating devices!
It can be seen from the two Chinese characters of "bearing" that this component has two main functions, one is rotation, and the other is loading!
What is difficult for Professor Wan Shen's team now is the problem of carrying capacity!
At present, the world's most load-bearing bearings can bear about 30 tons of weight, of course, this number is a bit exaggerated, because the bearing design can not only look at the load-bearing, but also calculate the bearing life, comprehensive consideration of load, impact pressure, speed and other working conditions, after the calculation to meet the design life can be.
However, a rough calculation can know that to cold roll the steel embryo into a steel plate, the weight of the rolling steel plate is very amazing, not to mention the load-bearing roller located in the lower part of the steel plate, it needs to withstand the pressure of the working roller and the weight of the steel plate, and the pressure on the bearing can be imagined!
What restricts the bearing carrying capacity is the material, so in order to completely solve this problem, you have to turn to material science experts!
At present, the general raw materials for the manufacture of bearings are bearing steel. Bearing steels have high and uniform hardness and wear resistance, as well as high elastic limits. The uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, the distribution of carbides and other requirements are very strict, is one of the most stringent steel in all steel production, but this steel has undergone unknown people's continuous research, the current material properties have almost reached the limit, to improve its strength and performance on a large scale, it is not easy to estimate!
There was no way, Professor Wan Shen could only recruit troops in the Magic Cave Club and hire experts in material science to join the group....
The difficulties are not only limited to the materials of the parts, but also the design of structural design, drive mechanisms, transmission devices, cushioning and resonance disaster reduction, etc., and the whole list can be a long list....
Now Professor Wan Shen understands that this thing is much more difficult than shield machines and bridge erecting machines, and the fields and disciplines involved are getting bigger and bigger!
Professor Wan Shen sometimes jokes with his colleagues in his research institute that the task of the Great Devil King, like a footcloth for a woman with small feet, does not seem to be a big deal, but if you really want to untie it, you will find that the longer and longer it pulls, the more flavorful it is!
Another expert also shook his head and smiled bitterly, more like peeling an onion, peeling layer after layer, layer by layer, layer by layer, endlessly, and spicy eyes....
In his institute, there are several experts in materials science and electronics, who were transferred from the 301 Institute to the 801 Academy of Sciences, and they have a sense of déjà vu about the current scene, as if the continuous controllable nuclear fusion research of that year is this smell!
At that time, the predecessor of the 301 Institute, the Institute of Zhonghai Physics of the Academy of Longkes, also felt that nuclear fusion was not a big deal, they had been studying on it for 15 years under the leadership of Academician Li, and as a result, the technical materials of the Great Demon King were on the table, the more complex the research, the bigger the stall, and more and more researchers were assembled, until finally, the Zhonghai Physics Institute was crowded like a vegetable market!
Isn't this also true of today's ultra-wide rolling mills?
They immediately told the story of the Zhonghai Institute of Physics to Professor Wan Shen, and the old Wan who listened to it shrugged his eyebrows!
Fooled!
Just know that the Great Demon King will not be so kind, and release a task with such a rich reward for points out of thin air, so that everyone can take advantage of him!
Now that he knows that the Great Demon King has such a previous conviction, he doesn't need to think about it, and he knows that this task is only based on the strength of their research institute, and it is estimated that he does not want to complete it independently....
......
With the increasing number of experts aware of this problem, various large and small research institutes began to merge according to different research goals, and finally formed 5 large-scale research institutes, and it is precisely because of this integration and concentration of forces that the research speed of each project has been further accelerated, and each key link and difficulty has been overcome little by little, and slowly began to show signs of success!
As the initiator, Kong Bai is now fully engaged in the overall structure planning and design of the "Aerospace Multi-purpose Strategic Platform", and is drawing drawings with Dabai and Erbai day and night!
The drawings he drew this time are not the same as any previous drawings of any project!
Compared with the huge and complex "space-space multi-purpose strategic platform", the drawings drawn by those previous projects, including the overall facility for continuous controllable nuclear fusion, are all "small dishes"!
As mentioned earlier, the "space-space multi-purpose strategic platform" technology that Kong Bai exchanged from the system is only the basic structure of a outer space facility, what kind of functions need to be realized inside, and secondary development and further design are needed on the basis of this technology!
Simply put, the technology exchanged to him by the system is like a rough house with only a preliminary overall structure, and if he wants to achieve what kind of function in this house, he needs to design, transform and plan and build by himself!
What Kong Bai is doing now is to carry out complex interior decoration for mankind's first "Battlestar Galactica"!
In Kong Bai's plan, this "space fortress" will realize the functions of space elevator, space gas station, space material transfer and storage center and turnover station, space maintenance station, astronaut training base and so on.
In order to achieve such complex and diverse tasks and functional requirements, Kong Bai needed to design various facilities inside Battlestar Galactica to the smallest on the basis of optimizing the space layout.
These designs not only include the reasonable layout and distribution of power supply, water supply, oxygen supply, heat supply and other various loads inside the "Battlestar Galactica", but also need to design complex external equipment, equipment in the wall, internal devices, connectors, various lines, pipelines, transfer points, etc., but also consider factors such as air tightness, water tightness, insulation, heat insulation, radiation protection and so on in these designs, and there are many key nodes to an outrageous degree!
It's just that, in fact, it's nothing, relying on the wisdom of the super crowd and the terrifying computing power of Dabai and Erbai, it is not too laborious, the most critical problem is that this "space fortress" is located in a vacuum, and the problem of disaster control and isolation between cabins must be comprehensively considered!
What do you mean?
That is to say, while completing the overall functional design and layout, it is also necessary to consider how the "Battlestar Galactica" can respond to and control the scope of disaster losses in a timely manner once it is hit by meteorites or other flying objects, missile attacks, cosmic high-energy particles, radiation of rays, etc., and establish escape and rescue channels, continuous and infectious losses, establish isolation areas or safety cabins, and so on!
According to Kong Bai's design requirements, in the case of 66% of the overall loss of "Battlestar Galactica", the unhit part still requires the supply of basic elements such as water, electricity, gas, heat, and food to maintain basic survival, so that the surviving people, or artificial people, can maintain at least 72 hours of survival in this safe area in order to wait for the arrival of external help!
Space exploration and travel are extremely dangerous, so they must be achieved with all aspects in mind, without the slightest negligence!
Many times, when the accident does not occur, it is impossible to see which aspect of the overall design is defective, but once one day unfortunately happens, every small negligence or defect is a fatal thing!
Such a design work, without the wisdom of the super crowd and the help of Dabai and Erbai, is absolutely desperate, and even with their help, Kong Bai feels a little tired!
The most unacceptable thing is that this design involves the whole body, once a defect or bug is found, major surgery is required, and the workload is as large as starting from scratch!
Figuratively speaking, it is like a box pushing game, if you want to move a certain box inside to a specific position, then you have to move almost all the boxes!
Every time Kong Bai finishes designing, the overall design scheme will be simulated through super crowd intelligence, simulating the various systems in the cabin, the establishment and maintenance of the biosphere, the balance of the life support system, the load of various pipelines, etc. under various working conditions and known cosmic ray radiation.
Every time such a test can find big and small problems, especially for the first time, on the entire "Battlestar Galactica" perspective, the red dots that mark the anomaly are everywhere, dense, and even make Kong Bai have the urge to smash something....
And then there's the big side modification!
Soon, Kong Bai found that this modification is more laborious than starting from scratch, especially all kinds of pipe lines that are as dense as spider webs, moving here, moving there, and then changing and changing, it becomes a mess, it is better to completely overturn and start again!
So, Kong Bai was helpless, sighed deeply, the fist in his hand loosened and tightened, tight and loose, and finally made up his mind to completely start from scratch!
And then the second time it was much better!
It's not that the abnormal red dots are much less, but Kong Bai's mentality in the face of this setback is much better!
Kong Bai re-examined his design concept and original intention, and felt that he was too perfectionist, as the first step of human beings to step into outer space on a large scale, his design concept was too advanced, and he wanted to do everything perfectly, and he might end up with one or the other.
As a result, Kong Bai began to feel distressed about the deletion function of adding flesh pain, and every time he deleted an item, he had to hesitate for a long time, just like that, the difficult design work staggered forward between this back and forth limit pull, and time slipped away unconsciously....
In the blink of an eye, it's May.
Unlike the virtual magic cave that is full of busyness and quiet years, the outside world is now cloudy and full of gunsmoke, and the tension between the beautiful and the new dragon has reached a hair-trigger tension!
