Doomsday Bunker Upgrade

Now that the direction is determined, the results will naturally be obtained soon.

Soon a report was put in front of Chen Xin.

Foam metal is indeed a very good material, with certain strength and ductility, and the internal foam-like structure can make it absorb the energy brought by impact like ordinary foam materials, and its application prospects are very broad.

But in construction, this material is more used in laminated composite materials, and will not be used alone.

After all, even if the strength of the foamed metal material is not bad, the static force that a foamed metal and a solid metal ingot can bear is obviously greater than the latter.

Foamed metal is not that it can’t be used as support. Like airplane fuselages and oil well platforms far from the shore, thin-walled cylindrical shells are easily damaged when subjected to loads. However, if the shell is supported by continuous foamed metal coils, the structure is similar The diameter and size of the unreinforced center shell has greater strength.

But that is a special application environment, which is not the same as the high-strength and light-weight materials required for the dome support structure.

But Chen Xin didn't mind this. The strength of the foamed metal material is not enough to be used as the main material, which does not mean that this material cannot be used.

Because the foamed metal material itself is not used as a separate material.

"Using foamed metal materials as the filling, and then using other high-strength materials as the framework, can we create supports that meet the support requirements of the dome structure while also reducing the cost?" Chen Xin expounded his own ideas and asked other people.

"In theory, it should be possible, but whether it can be done or not, it needs to be tested, and the specific material selected must also be tested." A material science researcher responded to Chen Xin's inquiry.

Hearing this answer, Chen Xin nodded and said, "Then do it. We should do experiment and experiment, we should do test and test, 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 set of feasible solutions.

"After testing, we determined that using high-strength materials as the framework and foamed metal materials as fillings 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 meet the design requirements. Requested." A researcher submitted their test report to Chen Xin.

After Chen Xin upgraded the scientific research center's supercomputer, the entire scientific research center now does not use much 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 before asking: "The total weight of the dome has increased by 30% compared to the original. Can this weight meet the design requirements? You confirm with the design department. Have you passed yet?"

"It has been confirmed. The result given by the design department is to adopt our current plan. The safety range of the total weight of the dome is 45% more than the original weight. If the key parts are reinforced and the structure is optimized, this value can be enlarged. To 60%, with our current plan, it can already meet the requirements." The researcher replied to Chen Xin, with a trace of excitement on his face.

"What about the cost?" Chen Xin is not surprised that the new scheme can meet the requirements in terms of structural strength and weight. He is more concerned about the cost issue.

The researchers obviously understood that the cost issue was the main reason they came up with this plan, so they replied: “The cost of our current plan is about 60% lower than the original design, and it can fully meet the requirements mentioned above. Requirements for the construction of a dome city."

Hearing what the researchers said, Chen Xin nodded in 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 changes as soon as possible. Design drawings."

"Yes, academician, we will finish it as soon as possible." The researcher nodded, and then left Chen Xin's office.

After the researchers left, Chen Xin leaned back on the chair and let out a sigh of relief.

Reaching out and tapping twice on the desk top, he called up the design drawing of the dome city and projected it out. Chen Xin said to himself: "Since the cost of the dome city construction is no longer a problem, it can be done according to My previous idea was to build a city cluster.

A dome is an urban area, and multiple domes are connected to form a ‘big city’.

Hmm... it seems that there is no need to use multiple domes. A large dome and several small domes are combined together to form a city. The large dome can be used as the main functional area, and the small dome can be used as a residential area..."

Chen Xin muttered to himself, and the projection on the table changed 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 rang in the office and a blue female face appeared in Chen. On the new desk.

This is the artificial intelligence installed by Chen Xin after the supercomputer upgrade of the scientific research center. In addition to providing computing power support for all research departments and researchers in this scientific research center, UU Reading www.uukanshu.com is also the scientific research center. The big housekeeper.

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. Set up rules to deal with the affairs of the scientific research center.

It can be said that in addition to the things that must be confirmed and handled by Chen Xin, the research center is now handled by this artificial intelligence. She is equivalent to Tang Tang's role, but compared to Tang Tang, artificial intelligence The efficiency and triviality of handling things are far superior.

Of course, artificial intelligence will be a little bit dull when dealing with things, and will only proceed in strict accordance with pre-set procedures and regulations. It is not as flexible as humans.

As for why she made suggestions to Chen Xin, it was Chen Xin who opened her auxiliary function and asked her to calculate the cost-effectiveness of these ideas.

"Xiyao, calculate whether the structure can support if the dome 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.
