Now that the direction has been determined, the results will naturally be obtained soon.
Soon a report was placed in front of Chen Xin.
Foam metal is indeed a very good material, with a certain degree of strength and ductility. The internal foam-like structure allows it to absorb the energy caused by impact like ordinary foam materials. It has a wide range of application prospects.
But in construction, this material is more commonly used in laminated composite materials and is not used alone.
After all, even if the strength of foam metal materials is not bad, the static force that a piece of foam metal and a solid metal ingot can withstand is obviously greater than the latter.
It is not that foam metal cannot be used for support, such as aircraft fuselages and oil well platforms far away from the shore. Thin-walled cylindrical shells are easily damaged when subjected to load. However, if the shell is supported by a continuous foam metal coil, the structure is much weaker than the same structure. diameter and size of the unreinforced center shell for greater strength.
But that is a special application environment, which is different from the high-strength and lightweight materials required for the dome support structure.
But Chen Xin didn't mind this. The strength of the foam metal material was not enough to be used as the main material, which did not mean that this material could not be used.
Because the foam metal material itself is not used as a separate material.
"Using foam metal materials as filling, and then using other high-strength materials as the skeleton, can we create support parts that meet the support requirements of the dome structure and at the same time reduce costs?" Chen Xin elaborated on his ideas and asked other people.
"Theoretically it should be possible, but whether it can be done specifically needs to be tested, and the specific material selected must also be tested." A researcher in materials science responded to Chen Xin's inquiry.
Hearing this answer, Chen Xin nodded and said: "Then go do it, do experiments when necessary, do tests when necessary, and give me a result as soon as possible."
———————————————
Although Chen Xin did not provide additional help for this matter, these researchers themselves quickly came up with a feasible solution.
"After testing, we determined that using high-strength materials as the skeleton and foam metal materials as the filling can indeed replace the original high-strength lightweight steel. Although the total weight of the dome is still 30% heavier, the strength and weight can already meet the design Requested." A researcher submitted their test report to Chen Xin.
After Chen Xin upgraded the supercomputer of the scientific research center, everyone in the entire scientific research center no longer uses paper, but uses tablet computers to directly transfer files, which also makes the entire scientific research center look full of science fiction.
Chen Xin quickly browsed the report submitted by the other party, turned to the final result and took a serious look at it before asking: "The total weight of the dome has increased by 30% compared with the original. Can this weight meet the design requirements? Can you confirm with the design department? Have you passed?"
"It has been confirmed. The results given by the design department are based on our current plan. The safe range of the total weight of the dome is 45% more than the original weight. If key parts are reinforced and structurally optimized, this value can be enlarged. To 60%, with our current plan, we can already meet the requirements." The researcher replied to Chen Xin, with a hint of uncontrollable excitement on his face.
"What about cost?" Chen Xin was not surprised that the new plan could meet the requirements in terms of structural strength and weight. He was more concerned about the cost issue.
The researchers obviously understood that the cost issue was the main reason why they came up with this plan, so they replied: "The cost of our current plan is about 60% lower than the original design, which can fully meet the above mentioned requirements of affording two seats at the same time. Requirements for Dome City Construction.”
After hearing what the researcher said, Chen Xin nodded with satisfaction and said to him: "In that case, submit this report to the design department and modify the design drawings according to this plan. I hope to see the revised results as soon as possible. design drawings.”
"Yes, academician, we will complete it as soon as possible." The researcher nodded and then left Chen Xin's office.
After the researchers left, Chen Xin leaned back on his chair and let out a sigh of relief.
He reached out and clicked twice on the desktop of his desk, called up the design drawing of the dome city, and projected it. Chen Xin said to himself: "Since the cost of building the dome city is no longer a problem, then it can be done according to the My previous idea was to build city clusters.
A dome is a city area, and multiple domes are connected to form a 'big city'.
Hmm... It seems that there is no need for multiple domes. One big dome and several small domes can form a city when combined. The big dome can be used as the main functional area and the small domes as residential areas..."
Chen Xin was talking to himself, and the projection on the table was changing with his thoughts.
"Academician, in terms of urban planning and construction costs, a large dome and several small domes attached to the large dome are a more suitable solution." A voice sounded in the office, and at the same time a blue female face appeared on the floor. On the new desk.
This is the artificial intelligence that Chen Xin installed after upgrading the supercomputer of the scientific research center. In addition to providing computing power support for all research departments and researchers of this scientific research center, she is also the general manager of this scientific research center.
Through the cameras and other electronic equipment installed in the scientific research center, it can be said that the entire scientific research center is under her control, and Chen Xin shared part of her control authority with this artificial intelligence, allowing her to follow the predetermined instructions. Set good rules to handle various affairs of the scientific research center.
It can be said that except for things that must be confirmed and handled by Chen Xin personally, all large and small things in the scientific research center are now handled by this artificial intelligence. She is equivalent to Tang Tang's role, but compared to Tang Tang, the artificial intelligence The efficiency and triviality of handling things are far superior.
Of course, artificial intelligence will also be a bit rigid in handling things. It will only strictly follow pre-set programs and rules and is not as flexible as humans.
As for why she made suggestions to Chen Xin, it was because Chen Xin turned on her auxiliary function and asked her to calculate the cost-effectiveness of her ideas.
"Xiyao, calculate whether the structure can support the dome if it is built according to this structure." Chen Xin adjusted the projection on the table and gave new instructions to the artificial intelligence.
"Yes, academician." After accepting Chen Xin's instructions, Xiyao started a new calculation.
