"Dean Qiao, I have admired my name for a long time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info "Chu River Channel.

"Oh, Boss Chu has heard of me?" Qiao Tianhong said with some surprise.

"Of course, I once read Dean Qiao's scientific research report on the first phase of the Qinghai-Tibet Railway project, and at that time, these were all things that I saw after I found the newspaper. Because I am more interested in railways, I am also more concerned about this aspect of registration. Chu Jianghe explained.

Qiao Tianhong has a lot of research reports and articles on railway lines, which have been published in the People's Daily in a large space, and Chu Jianghe was influenced by some of Qiao Tianhong's thoughts in his previous life.

"It seems that Boss Chu knows a lot about the railway, and I am becoming more and more interested in the concrete sleepers you draw. Qiao Tianhong said with a smile.

Although Qiao Tianhong is now retired, it is inevitable to be a little relieved to hear that some juniors have heard of his articles and deeds.

This is Professor Wang from the Department of Civil Engineering at Shanghai Jiao Tong University and Professor Li from Tsinghua University. Li Xianden continued.

Compared with Director Sun and Qiao Tianhong, Professor Wang is obviously much younger, and he looks like he is in his fifties, but at this age, the people who can be called professors are not ordinary people, they often have their own works and influence in a certain field.

Professor Li is serious among the four, the oldest, should be seventy years old, and his eyebrows are all white.

Although Chu Jianghe was not familiar with these two professors, he did not despise them, these four experts, whether in terms of knowledge or foresight, were not inferior to themselves, and they relied on the memories of their previous lives.

"You may be seated. After the introduction, Li Modern gestured.

Subsequently, Li Modern sat down on the main seat, with four experts on the right, and in addition to Chu Jianghe on the left, there were two employees of Li Modern Company.

After everyone sat down, Li Modern said: "Today, I invite four experts to come to discuss whether the new sleeper drawings drawn by Boss Chu can be used in the line, once it is confirmed that it can be used, we will apply for a patent, and report to the Ministry of Railways for approval by the bureau." ”

As a new type of sleeper, used in the railway, in the eight years, it still needs the approval of the relevant departments of the Ministry of Railways, but the subordinate railway bureau has the right to recommend.

As for applying for patents, under normal circumstances, such patents are applied for in the name of the bureau, ministry or state, and there is no example of individual application, because in the previous research and design, some experts have developed them, and for these new materials and equipment, experts will generally apply for the right to apply for patents for their own state-owned enterprises, and they will receive corresponding rewards.

If Chu Jianghe applies for a patent for a type II sleeper in the name of an individual, this will be the first case in the history of domestic railways.

"Next, we will hand over the time to Boss Chu and the four experts. Li Modern said to make a long story short.

After Li Xiandeng finished speaking, Chu Jianghe had already taken out a stack of papers from his bag, which were all drawn by Chu Jianghe himself, including Type II sleepers and matching sleeper fasteners.

"Four experts, this drawing was left to me by the previous educated youth, because I was very interested in railway things, and I also learned a lot at that time, you can take a look first. "The Chu River channel.

After speaking, Chu Jianghe handed a few drawings to Director Sun and others.

After the four experts took it, they began to look at it, and when Qiao Tianhong was watching, he was still drawing pictures in his notebook, didn't he ask Chu Jianghe a few words.

For the questions asked by Qiao Tianhong, Chu Jianghe answered them all and provided data for Qiao Tianhong.

"Old Qiao, how is it?" Professor Wang asked with a curious expression.

For the stress of the sleeper, Qiao Tianhong is an expert in this area, no matter how the sleeper, first of all, it is necessary to analyze the mechanics and whether it is suitable for promotion.

Qiao Tianhong put down his pen, fell into contemplation, and said: "According to the data provided by Boss Chu, this new type of sleeper does have the effect of buffering the impact of train operation, but I still can't understand the elastic bar fastener you draw, why do you draw this shape instead of other shapes?"

"Dean Qiao, how fast did you calculate?" Chu Jianghe asked.

"80km/h calculation. Qiao Tianhong said.

"Then you use the method of mechanics to calculate the force of the sleeper according to 100km/h, and you see what the result is. Chu Jianghe proposed.

The advantages of type II sleepers are not very obvious in low-speed railways, but once they reach high-speed railways, compared with the new type I sleepers, their advantages will rise rapidly.

Qiao Tianhong and the others were stunned, they didn't know what the purpose of Chu Jianghe's proposal was, but Qiao Tianhong still listened to Chu Jianghe's suggestion, and in less than ten minutes, Qiao Tianhong's calculation was completed, and when he saw the result of the calculation, Qiao Tianhong was stunned.

From the point of view of mechanical calculation, the sleeper designed by Chu Jianghe, the higher the speed of the train, the better the buffering effect, which is extremely rare in mechanics, mainly because the design of this new type of sleeper section just reduces the buffering force of the train.

"How is it possible!" Qiao Tianhong exclaimed, revealing an incredible look.

"Old Qiao, what's wrong?" Director Sun and Qiao Tianhong have known each other for a long time, and he has never seen Qiao Tianhong lose his temper like this, obviously, Qiao Tianhong has made a major discovery, which can be seen from Qiao Tianhong's excited and puzzled expression.

"This new type of sleeper has a good dynamic load buffering effect on the train, and according to the mechanical calculation, it far exceeds the Ia sleeper!" Qiao Tianhong came to such a conclusion.

"So amazing?" Professor Wang looked surprised.

On the opposite side, Chu Jianghe picked up the teacup and drank the tea slowly, this result had long been expected by Chu Jianghe.

Looking at Qiao Tianhong's excited look, Li Modern glanced at Chu Jianghe with admiring eyes, which can convince Qiao Tianhong and Qiao Lao, which is enough to prove that this new type of sleeper is indeed usable.

"Dean Qiao, I will ask you to use the train speed of 160km/h and 200km/h to calculate the force on the sleeper. Chu Jianghe put down the teacup and spoke.

Hearing Chu Jianghe say this, even Director Sun was stunned, Chu Jianghe was so calm, he must be very confident in his own design drawing.

At present, the domestic railway running speed, can drive to 100km/h has been very fast, for the speed of 160km/h, the country is still in the study, can not do all aspects of the promotion, not to say that the speed of the train can not open 160km/h, but to this speed, the train below the rails, sleepers, ballast, bridges, roadbed, there is a great test, really to build such a railway, the investment and construction cost is too high.

In the previous life, the Beijing-Shanghai high-speed railway was built at three times the construction cost of ordinary railways, and it took a lot of money to succeed in China, and there were still many problems left in the later stage.

Not to mention, in the past eight years, it is impossible for China to spend several times the cost of ordinary railways to develop high-speed railways.

Qiao Tianhong did not have the slightest doubt about Chu Jianghe's suggestion, he quickly put pen to paper and began to calculate, with the previous two calculations, this time, it took a lot less time.

After the calculation, Qiao Tianhong couldn't suppress his joy and praised: "Boss Chu, is this new type of sleeper really designed by you? If this sleeper is promoted, the speed and progress of China's railway can be raised to a big level." ”

"Old Qiao, it's really so amazing. Professor Li frowned.

"Elder Li, look at my calculation process and see if there are any problems. Qiao Tianhong handed the paper of his calculation to Professor Li.

After Professor Li and Professor Wang took it, they carefully checked it.

"However, Boss Chu, although this kind of sleeper is very suitable for promotion, once the speed reaches 160km/h, the existing fasteners cannot meet the speed requirements!" Qiao Tianhong put forward the problems found in his calculation process.

This new type of sleeper, for the development of the railway, is indeed suitable, but with the increase of speed, the existing buckle fastener, can not bear the impact of the dynamic load of the train, if this problem is not solved, this sleeper, still can not be promoted.

"Dean Qiao, there is actually an answer to this question, in the drawings I gave you, in addition to the design drawings of the sleepers, there are also a few design drawings about elastic bar fasteners, this kind of fasteners can solve some of the doubts raised by Dean Qiao!"

"Spring bar fasteners?" Qiao Tianhong was stunned, he didn't see the drawings he had just received, he thought that Chu Jianghe had drawn a few drawings of the new type of sleepers, but now it seems that it is obviously not.

"Old Qiao, here. Director Sun handed over the drawings.

After Qiao Tianhong took it, he looked at it carefully, and then frowned, thinking that he had found that he couldn't calculate this kind of elastic bar fastener for a while!

The main thing is that if you are new to this kind of thing, even if you are an old expert, there are times when you miss it.

"Boss Chu, can you help me explain. Qiao Tianhong looked up at Chu Jianghe, without the slightest embarrassment, for research matters, if you don't understand, you don't understand.

"No problem. Chu Jianghe got up and walked over, Professor Wang hurriedly gave up his position, stepped back a seat to the side, and gave way to Chu Jianghe.

At this moment, although the four of them were experts, they admired Chu Jianghe and did not have a trace of contempt.

Chu Jianghe explained the placement of the fasteners to Qiao Tianhong clearly, and then Qiao Tianhong understood the design of the stress point and the radius of the bending arc, because only in this way could Qiao Tianhong carry out the next mechanical calculation.

As for this kind of mechanical calculation, of course, Chu Jianghe can't say that he understands, he can only rely on Qiao Tianhong to calculate, and only the data of the elastic bar fastener provided by himself provides a basis for Qiao Tianhong's calculation.

The more Qiao Tianhong calculated, the more excited he became, because he found that the cushioning force that this kind of elastic bar fastener can withstand is more than ten times that of the existing gusset plate, and once this elastic bar fastener is installed on the railway, the stability of the rail will be greatly improved.

It can be said that the design of the elastic bar fastener makes the dynamics perfectly presented on the railway!

However, in the process of calculation, Qiao Tianhong found another problem, which made his brows tighten. (To be continued.) )
