The car passed by Kangka, He Tao also proposed to go to the construction site of the new city to have a look, Guan Fei as he wished, and drove on the road between the two mountains to the new city.

The tour bus behind also followed, and did not go directly to the military subdivision on the main road.

When he arrived at the construction site of the new city, He Tao looked straight at it, tens of thousands of people started work at the same time on a construction site, such a huge construction scale has rarely been seen in China in the past two years. The speed of construction of the new city also amazed him.

From the report, he knew that the first project of the university town, in addition to the main project of the teaching building, the student dormitory, laboratory building, gymnasium, etc. have not yet been completed.

But the words are always dry, and when he saw a large campus covering an area of thousands of acres, the transplanted grass, flower beds, artificial lakes, rockeries, pavilions, tennis courts, circular sports fields, as well as student dormitories, libraries, and large indoor gymnasiums that can accommodate thousands of people, he still showed a shocked expression.

When he looked up at the teaching building that had been built to the eleventh floor, and there was still one floor to be capped, his expression was extremely serious.

It can be said that this is a school that will be opened immediately.

The scale of 2,000 acres is limited by the urban topography, and it is much smaller than many universities in China that often cost tens of thousands of acres. However, many universities in China are comprehensive universities, and one university contains two comprehensive disciplines of arts and sciences, and there are many departments below.

The planning drawings designed by Guan Fei are aimed at a specific discipline for each university. Not counting the School of Economics and Management, the School of Medicine, all universities are pure science and engineering!

After coming out of the school, they went to see the construction of residential areas and commercial areas.

Looking at a small high-rise building with twelve floors in the entire community, and more than two elevators in each building, he was even more moved.

This is a high-end residential area, even provincial and municipal cadres in China still live in government compounds. Maybe the room size is bigger, the living environment is better, but no one can live in the elevator apartment!

When he heard that this was only the first batch, it was an ordinary apartment building, and high-end villas would be built on the bank of the river in the future, he was even more speechless.

If such conditions are really completed, it is really not worse than that of developed countries abroad.

When they passed by a sewer pipeline construction site under construction, He Tao was so excited that he also went in to watch it.

He found that it was more of an underground pit than a sewer.

The sewers, which are three meters wide and two meters high, are buried deep underground, and the top of the tunnel is fifteen meters above the ground. In the whole tunnel, various pipes of different thicknesses are fixed in an orderly manner. There are sewage pipes up to half a meter thick, and there are also water pipes of twenty or thirty centimeters, with electrical pipes on the left wall and telephone lines on the right wall. Every 10 meters, a support column will be set up in the center of the tunnel.

All the lines are concentrated in this passage, which is convenient for staff to inspect and maintain at any time. If something goes wrong, it's also very easy to repair and replace.

They stopped and stopped all the way, getting out of the car from time to time to take a closer look, and it was not until the afternoon that they arrived at the location of the military sub-district.

This time, He Tao didn't have the opportunity to express his feelings about Guan Fei's simplicity.

The army divisions, brigade headquarters, and companies have all moved into new barracks, and the valley of about one square kilometer has been divided into a regular checkerboard pattern by a group of brand-new buildings. Dozens of three-storey barracks are stacked on top of each other, each with its own separate courtyard for gathering troops and giving lectures.

The barracks were not only a place for the soldiers to rest, but also a place for learning and recreation.

In each barracks, a large conference room and a small conference room were set up. There is also an activity room of about 200 square meters, which is divided into a badminton court, a volleyball and basketball indoor sports field. There is also an open space on the side, where a table tennis table made by the wooden factory of the military sub-district is placed.

In the large conference room, he also saw a wide curtain and projector rolled up – which also doubled as a small cinema!

Such comfortable conditions have nothing to do with simplicity, they are simply great, and compared with the best army barracks in the country, they are not bad at all, and they are still exceeded!

The soldiers I saw along the way were all in good spirits, and from time to time I heard bursts of laughter from the soldiers.

From this laughter, it can be seen that the fighters are very satisfied with the current conditions. Good living and living conditions, in turn, promoted the soldiers' sense of belonging to this fighting collective. The momentum of the development of the military sub-region has also made these soldiers full of confidence in the future development of the military sub-region and willing to obey the arrangements of their superiors. The preferential treatment policies for soldiers in the army, such as training in veterans' skills and the distribution of packages, have further tied the soldiers' future closely to the military sub-divisions, and their fighting courage and will and determination have been greatly enhanced.

If the last time people came to the capital, they saw the possibility of the future development of the military sub-district, then He Tao now, through his observation, this possibility has been transformed into a real thing.

It is enough to understand this.

On this trip, what they, especially the two old professors, Zhao Wenliang and Fan Zhe, wanted to know most about the current technical strength of the military sub-district.

Originally, they thought that they would not see much until the factories were officially opened. Who knows, before they arrived at the technical school, they made new discoveries.

At that time, the car was about to pass through a small valley when a very loud knocking sound was heard from inside, which was continuous.

"What kind of place is this? Why does it seem so noisy? ”

Seeing that the tourist bus stopped behind, Guan Fei just got off the jeep that was reversed, and was pulled by Fan Gong and asked.

It just so happened that a liberation truck drove in, and through the open rear panel of the compartment, several steel workpieces could be seen on it. The surface of the workpiece is dark in some places, as if it has been burned by fire.

"This is freshly heat-treated?" Fan Zhe's eyes were very poisonous, and he could see at a glance that this was a workpiece that had just been heat-treated.

"That's right! This is where we stress reliev, rough-machined workpieces, sent for heat treatment, and then hammered for a long time by a vibratory stress hammer to relieve the internal stresses of the workpiece. "There's nothing to hide," Guan Fei said generously.

"Eliminate internal stress with a vibratory hammer!" Fan Zhe's eyes lit up at once.

Stress is the internal deformation of an object due to the inability to move after being subjected to external forces such as impact and burning.

It's as if a person is struck and can shrink into a ball. Various materials such as steel and wood will also change internally after being subjected to external shocks, and the stronger the blow, the greater the change. These deformations, in turn, will gradually stop after a long time, which is called stress relief.

In ancient times, people knew that freshly cut wood could not be used directly, because firewood would be twisted and deformed after shrinking and drying. Therefore, the ancients would leave the cut wood for a year or two, so that the inside of it had been completely eliminated from moisture, and the deformation was completed, before it was processed and made into ship boards, furniture, etc.

The same goes for steel.

In the early days, when the accuracy requirements were not high, there were generally only links such as lathe production, and the steel needed to be stress-relieved. If there is no strain relief equipment, when the strain relief is made, some parts of the equipment may be deformed, which will reduce the work efficiency of the machine, increase the wear and tear consumption, seriously reduce the service life of the machine, and even completely scrapped.

In order to eliminate stress, the traditional method is the aging method, that is, as with wood, it is left in the open field, exposed to the sun and rain, and let it sit for a long time to release its internal stress.

This method works well, but it is too time-consuming.

For example, in a machine tool factory, to build a machine tool, it must smelt the required steel and alloy castings several years ago, and then let it sit to relieve stress. After the stress is eliminated, in the initial processing link, due to the violent collision of the tool on the material, new stress will be generated, so it is necessary to stand again.

Each time it stands, it takes months for the short ones to take years for the long ones.

Therefore, when the machine tool factory receives an order, if it is not to buy its finished products, but to redesign the production, there is no suitable part at hand that has been relieved of stress, then it may take five or six years from the receipt of the order to the completion of the final production, which can be described as quite a long time!

In the event of an emergency, such a lengthy stress treatment simply cannot meet the needs of the market.

The development of human science and technology is progressing with demand.

The need to quickly eliminate internal stresses in solid materials to meet flexible production needs led to the study of this aspect.

This research began in the sixties, due to the slow progress, limited research methods, and too long waiting time for verification results, after more than ten years, a relatively reliable and rapid method of stress relief was found, that is, the vibration method.

Isn't the stress generated by the impact, then we apply a certain force to it in the corresponding position to help it quickly release the stress, which is the research idea of the vibration method.

There are studies in this area abroad, and China is naturally following up quickly.

However, due to the impact of unrest, limited investment, and low level of automation, the progress of domestic research is very slow. Foreign countries have basically summarized the laws of vibration method and began to promote it in some industries, while the domestic ones are basically still hovering at a low level and cannot be practical.

What is now used in China is mainly the statute of limitations method and heat treatment method. The aging method takes a long time, needless to say, the heat treatment method is to put the workpiece into the kiln and burn it at the appropriate temperature, which is also a method of fighting poison with poison.

However, the heat treatment method is very difficult to relieve the stress in some special positions, and after heat treatment, the workpiece is deformed greatly, and it is necessary to carry out a processing. This processing may generate new stress, so it is a helpless choice with large investment, high energy consumption and not very satisfactory effect.

Fan Zhe is a senior engineer of the Mechanical Design and Research Institute, and he is naturally familiar with the vibration method.

"Can you go in and have a look?" His face lit up and he asked excitedly.

"Absolutely!" Guan Fei led the way with a smile, Fan Zhe was impatient to follow behind, Zhao Wenliang and the others didn't know anything about the vibration method, but they had nothing to follow over to watch the excitement.

Zhao Zhonghua is in charge of civil affairs, and after the construction of the new city is completed, he will play the same role as the mayor, so he comes to the technical school more often. The valley was stacked with heat-treated workpieces, and he knew it, and he had seen it, and he had seen the noisy thing, and he had heard a brief explanation of what it was for.

Because he was used to it, and to avoid the sound of the dead man, he rarely came here again.

But at this moment, seeing Fan Zhe's expression like a pervert seeing a beautiful woman, he unconsciously muttered in his heart: Could it be that noisy thing is actually a good thing?

He Tao didn't understand this, but he would observe words and looks, and as soon as he saw Fan Zhen's excited expression, he knew that Guan Fei had something good in his hand.

"What is that ......, strain relief?" He was very studious, chased after Professor Fan Zhe, and asked shamelessly.

After Fan Zhe's dancing and impassioned explanation, he understood.

Not only did he understand, everyone else understood. He Tao's face was flushed, and he felt that the blood on his body was surging upward.

Stress relief!

This technology is too important, too critical!

If this technology is available, then China can manufacture high-precision lathes, equipment, tank engines, fighter planes, and warships in large quantities according to needs......

"This vibration...... Is the vibration stress relief method your own technology? He immediately let go of Fan Zhe, grabbed Guan Fei and asked.

“…… It's intelligence ......"

"your intelligence monger!" Before Guan Fei finished speaking, he was blocked back by He Tao angrily, "I don't care if you bought it from an intelligence dealer, do you have this technology?" Not all at all? How long does it take to relieve the internal stress of a component? ”

Well, next time I'll say it's on the road!

Guan Fei regretted the disappearance of a good excuse, shook his head and explained to him: "Your question is not scientific!" The time required to relieve the internal stress of a component is related to its size, structure, and processing method. For large equipment parts, it takes a long time to relieve stress, and at the same time, the processing method is different, and the internal stress deflection size of the material is also different. I can only tell you a rough way that it takes several days to relieve the stress of a lathe bed......"

"I want this technology!" He Tao didn't wait for him to finish speaking, and cut the railroad to the end.

Just kidding, a few days, compared to years when the statute of limitations is often years, this little time is like nothing.

Don't be a fool with such good technology!

"I can sell a sub-vibration meter made in China, only 6,000 yuan each! As much as you want, I will give! ”

Guan Fei is also unambiguous and immediately interfaced.

Nonsense, even if Fan Zhe didn't find this thing, he would take the initiative to take them to see it. The circuit structure of this sub-vibration meter is very simple, and the difficulty of vibratory hammer processing is not high. The quotation of 6,000 yuan, the actual manufacturing cost is only 2,000 yuan!

This thing costs tens of thousands of dollars in foreign countries, and the key to its value lies in the setting of vibration frequency waves, which is high-tech!

In order to find a suitable vibration frequency wave, foreign countries spent more than 20 years, constantly perfecting and revising, and it was not until the 80s that it was finally finalized and popularized on a large scale. By the 90s, except for a few high-precision manufacturing, almost all factories used sub-vibration meters to eliminate internal stress on the workpiece.

It was only in the nineties that China began to gradually learn this technology. But at that time, there was already a better strain relief technology, and this thing was very frivolous, and it was sold publicly on the Internet, and there were few buyers.

But in this day and age, it's really a big killer!

To make money, it is not a good thing to sell at a high price, but more importantly, to choose the right time. What people are striving for is the hot technology to make money!
