Chapter 827

Now that the direction has been 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 a certain degree of strength and ductility, and the foam structure can make it absorb energy from the impact just like ordinary foam material, and its application prospect is very extensive.

However, in construction, this material is more used in laminated composites and will not be used alone.

After all, even if the strength of the foam metal is not bad, but a foam metal and a solid metal ingot, the two can withstand the static is obviously larger.

Foam metal can not be used as a support, such as aircraft fuselage and offshore platform, thin walled cylindrical shells are easily damaged under load. But if the shell is supported by continuous foam metal coils, the structure has greater strength than the unreinforced center shell with the same diameter and size.

However, it is a special application environment, which is different from the requirements of high-strength and light materials required for dome support structures.

But Chen Xin did not mind. The strength of foam metal material is not enough to be used as the main material, which does not mean that this material can not be used.

Because foam metal material itself is not used as a separate material.

"Filling with foam metal materials, and then using other high strength materials as skeletons, can produce supporting structures that meet the requirements of dome structure and reduce costs at the same time?" Chen Xin elaborated his ideas and asked others.

"Theoretically, it should be possible, but whether it can be done or not needs to be tested, and the specific material selected should also be tested." a researcher in materials science replied to Chen Xin's query.

Hearing this answer, Chen Xin nodded and said, "let's do it. It's time to do experiments, tests, tests, and give me a result as soon as possible."

———————————————

Although Chen Xin did not provide additional help in this matter, the researchers themselves quickly came up with a feasible scheme.

"After testing, we determined that using high strength material as skeleton and filling with foam metal material can really replace the original high-strength steel. Although the total weight of the dome is still 30%, the strength and weight can meet the design requirements." a researcher submitted their test report to Chen Xin.

After Chen Xin upgraded the supercomputer of the scientific research center, everyone in the whole scientific research center now doesn't use paper much, but uses tablet computers for direct file transmission, which also makes the whole scientific research center look full of science fiction.

Chen Xin quickly browsed the report submitted by the other party, turned to the final result, took a serious look, and then asked, "the total weight of the dome has increased by 30% compared with the original, which can meet the design requirements? Have you confirmed with the design department?"

"It has been confirmed. The result given by the design department is that with our current scheme, 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 scheme, the requirements can be met." the researcher replied to Chen Xin, There was an uncontrollable excitement on his face.

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

The researchers clearly understand that the cost problem is the main reason why they came up with this scheme, so they replied: "the cost of our scheme is about 60% lower than the original design, which can fully meet the above requirements of bearing the construction of two dome cities at the same time."

Hearing what the researchers 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 scheme. I hope to see the modified design drawings as soon as possible."

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

After the researchers left, Chen Xin leaned back on his chair and breathed a sigh.

Reach out and click twice on the desktop of the desk, call out the design drawing of the Dome City and project it. Chen Xin said to himself: "since the construction cost of the dome city is no longer a problem, it is entirely possible to build the urban agglomeration according to my previous idea.

A dome is an urban area. When multiple domes are connected, it is a 'big city'.

Well... It seems that there is no need for multiple domes, one large dome and several small domes. Together, they are also a city. The large dome can be used as the main functional area and the small dome as the residential area... "

Chen Xin was talking to himself, and the projection on the table was changing with his ideas.

"Academician, in terms of urban planning and construction costs, a large dome and several small domes attached to the large dome are a more appropriate scheme." a voice sounded in the office, and a blue female face appeared on Chen Xin's desk.

This is the artificial intelligence installed by Chen Xin after upgrading the supercomputer of the scientific research center. In addition to providing computational support to all research departments and researchers of the scientific research center, she is also the housekeeper of the scientific research center.

Through the cameras and other electronic devices installed in the scientific research center, it can be said that the whole scientific research center is under her control, while Chen Xin shares part of her control authority with the artificial intelligence, so that she can handle all the affairs of the scientific research center according to the preset rules.

It can be said that in addition to the things that Chen Xin must personally confirm and deal with, the large and small things of the scientific research center are now handled by this artificial intelligence. She is equivalent to the role of Tang Tang Tang, but compared with Tang Tang Tang, the efficiency and trivial degree of artificial intelligence in dealing with things are much better.

Of course, artificial intelligence will be a little rigid in dealing with things. It will only be carried out in strict accordance with preset programs and rules. It is not as flexible as human beings.

As for why she made suggestions to Chen Xin, Chen Xin opened her auxiliary function and asked her to calculate the cost performance of her 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 issued a new instruction to artificial intelligence.

"Yes, academician." after accepting Chen Xin's instruction, Xiyao began a new calculus.
