"Old Qiao, how is it?" Professor Wang and Professor Li were correct, and looked at Qiao Tianhong. Pen "Fun" Pavilion www.biquge.info

"Perfect, this is definitely a genius idea, I never thought that the width of the sleeper would increase by a few centimeters, and the force would change so much!" Qiao Tianhong was surprised.

Mechanics, in ancient China, there are one or two thousand catties of saying, the use of clever words, in fact, is the performance of mechanics to the limit, some designs, make subtle changes, but have unexpected effects.

"Is it okay to travel at 200km/h?" asked Professor Wang.

"160km/h is completely guaranteed, for 200km/h, the sleeper can be fastened no problem, but there is one place where there may be a problem!" Qiao Tianhong frowned.

"Where is it?" asked Director Sun curiously.

If the speed of 200km/h can be guaranteed, it will create the possibility for the development of high-speed railway, once the speed of the train exceeds 200km/h, the requirements for all aspects have changed qualitatively.

If this sleeper can meet the speed of 200km/h is the running speed of the train, it is definitely a booster for the development of domestic railways!

"The rail, when I calculated just now, is to calculate the force of the sleeper with 50 rails, once the train speed is up to 200km/h, the 50 rail is obviously not very adaptable. Qiao Tianhong explained.

The rail is the main component of the railway track, and its function is to guide the wheels of the rolling stock forward, withstand the tremendous pressure of the wheels, and transfer to the sleepers.

Domestic rail models, in the memory of the Chu River, are divided into 38kg/m, 43kg/m, 50kg/m, 60kg/m, 75kg/m rails, in eight years, 38 rails have been discontinued, some slow railways, the use of 43 rails, only some speed of hundreds of railways, the use of 50 rails.

As for the 60 rails and the 75 rails for heavy-haul railways, they have not been produced at all and have not been developed, so when Qiao Tianhong calculates the mechanics of the sleeper, he only calculates according to the existing 50 rails.

Type II sleepers and bouncing fasteners, the most suitable rail, but 60 rails, once the speed of the train exceeds 200km/h, 50 rails will reveal his shortcomings, which is also where Qiao Tianhong raised doubts.

This kind of deficiency can be extracted from the mechanical calculation, and it can't hide the eyes of Qiao Tianhong and others.

"Old Qiao, don't say that the speed of 200, even if it can meet the speed of 160, it is enough, and it is undoubtedly a revolution for the railway industry!" Professor Wang was excited.

As experts in the railway industry, no one is so eager to hope that the railway industry of the motherland can develop rapidly.

"Wang Lao is right, it is good to be able to stabilize the speed of the railway at 160km/h!" Qiao Tianhong also nodded, feeling that he was too demanding.

Hearing the words of the two, Chu Jianghe smiled slightly, for this question, how could Chu Jianghe not expect that the development of bouncing fasteners originally appeared with 60 steel rails, and now he first proposed sleepers and bouncing fasteners, but he never mentioned the rails.

However, for the design drawings of 60 rails, Chu Jianghe has long been ready!

"Dean Qiao, do you think that this problem can be solved by widening the bottom of the rail, increasing the waist of the rail, and widening the head of the rail?"

Hearing Chu Jianghe say this, Qiao Tianhong immediately nodded and said: "Boss Chu is not a connoisseur, and he can see the problem at a glance, indeed this kind of bouncing fastener, in my words, is used on 50 rails, which is a bit wasteful, I always feel that he has not played the biggest role!"

"Actually, I have also considered this problem, I have drawn a drawing of a steel rail here, Dean Qiao, you can see if it is appropriate. Chu Jianghe got up, returned to the seat he was sitting on, and took out the other two drawings from the bag he carried.

Qiao Tianhong was stunned, took it in surprise, only glanced at it, and couldn't take his eyes off it, because the drawings given to him by Chu Jianghe were precisely the design drawings of a rail section!

"This ......" Professor Wang glanced at him, revealing a look of surprise.

"A new type of rail?" exclaimed Professor Li.

Although they were not sure whether Chu Jianghe's new rail drawings could be used, it was enough to prove that Chu Jianghe had long realized the shortcomings of the 50 rails and specially designed another kind of rail.

"Dean Qiao, please calculate whether you can maximize the role of the new sleepers and bouncing fasteners if you use this kind of rail. "The Chu River channel.

Qiao Tianhong looked excited, he used a little trembling hand, and began to calculate according to the new type of steel rail provided by Chu Jianghe, this time, Qiao Tianhong calculated very slowly, and in about fifteen minutes, Qiao Tianhong finally came up with the result.

"Old Qiao, how is it?" asked Director Sun expectantly.

"Perfect, perfect, this new type of sleeper elastic bar fastener is completely tailored for this new type of rail!" Qiao Tianhong exclaimed.

"Old Qiao, that is to say, not only this new type of sleepers and fasteners, but even this kind of steel rail, can also be popularized?" said Director Sun.

"Yes, once promoted, it will definitely be a historic revolution for the railway industry, and China's railways will move to a new height!" Qiao Tianhong was excited.

Li Modern didn't speak, waiting for the conclusion of the four experts, hearing Qiao Tianhong's words, Li Modern's hanging heart finally let go, and he looked at Chu Jianghe's gaze, admiring it even more.

"Old Qiao, can I help Brother Chu apply for a patent for this sleeper and rail?"

"The new type of sleepers and fasteners should be fine, for the new type of rail, I don't think there is such a need, after all, the production of rails, you can't be involved, you can't go to open a steel mill." Director Sun thought for a moment.

The production of sleepers does not require much investment, Li Modern's factory can be manufactured, but the rails are different, the steel mills nationwide are now all state-owned production, and it is impossible for private individuals to intervene, even if Chu Jianghe applies for a patent, the state may not approve it.

"Boss Chu, with all due respect, if I designed this sleeper, I would not apply for a patent, but would dedicate this design to the country. Qiao Tianhong put down the pen in his hand and smiled.

Regarding Qiao Tianhong's thoughts, Chu Jianghe just smiled slightly, and did not reply, now that Chu Jianghe is asking for money, he does not have such a high level of quality as Qiao Tianhong.

As the older generation of the country, he put the interests of the country first, Chu Jianghe can understand, but Chu Jianghe designed Type II sleepers and 60 steel rails in order to make money, not to make a Virgin watch.

"Dean Qiao, I'm really sorry, first of all, I'm a businessman, the reason why I came up with this design is to make a profit, if this design can't bring me profit, I don't need to spend so much effort, and let Modern invite four experts to study the feasibility of new sleepers and fasteners, I hope you understand. Chu Jianghe said apologetically.

"Boss Chu, I understand your thoughts, since you have made this decision, I have no objection, after all, everyone has their own ambitions, and what you said is also the truth. Qiao Tianhong nodded slightly, but it was obvious that when he heard Chu Jianghe's words, Qiao Tianhong showed a trace of regret in his eyes.

"Director Sun, I think this design should be reported to the ministry in the name of the Railway Bureau. Li Xiandeng looked at Director Sun and said.

"Yes, but I want to remind you that even if this design is reported to the ministry, the ministry still has to organize personnel to review it. Director Sun said.

Now only four people think it is feasible, and once these designs are reported to the Ministry of Railways, the Ministry of Railways will organize experts to study and discuss these designs.

After the meeting, Qiao Tianhong pulled Chu Jianghe and asked some doubts, and Chu Jianghe answered them one by one.

During the conversation, Qiao Tianhong was worried that even if Chu Jianghe applied for a patent, he would be copied by others, and Chu Jianghe just smiled at this problem, because in Chu Jianghe's opinion, unless the other party does the same as his own elastic fastener, once the elastic fastener is slightly changed, the force is completely different, and an accident is very likely to occur.

"Brother Chu, you can leave the matter of applying for a patent to me, and I will apply for it in your name first. After lunch, the four old experts went back to the hotel to rest, and Li Moden faced the Chujiang River.

"No problem, what I'm worried about now is that the leaders of the Chutan Railway Bureau will report these designs to the Ministry of Intent?" Chu Jianghe worried.

"It shouldn't be a problem to report, the key is whether the ministry is willing to promote it on a large scale, but before reporting, you must first apply for a patent. Li Modeng said.

Chu Jianghe has no opinion on this matter, with a patent, who will produce it in the future is Chu Jianghe's final say.

Whoever wants to use Chu Jianghe's patent has to give Chu Jianghe a patent fee, and after a year, Chu Jianghe can collect a lot of patent fees.

"Modern, in my opinion, I think it's an opportunity before the ministry agrees. Chu Jianghe said with a smile on the corner of his mouth.

"Opportunity, what do you mean?" Li Xianden frowned slightly, not knowing what Chu Jianghe meant.

"Yes, it is indeed an opportunity, can you contact Director Zhao, I want to meet with him, as for what the opportunity is, it is inconvenient to disclose it now. "The Chu River channel.

Seeing that Chu Jianghe was mysterious, Li Modern didn't care, what he cared about was whether Chu Jianghe's patent could become the first manufacturer, shrugged and said: "Director Zhao will go back to Shenzhen City tomorrow, if I can, I will see if I can arrange for you to meet with Director Zhao tomorrow night, but I can't guarantee that the other party will not see you." ”

"This is no problem, you just need to tell Director Zhao that this matter is related to the development prospects of the Chutan Railway Bureau in the next 20 years, and I believe that Director Zhao should meet with me. Chu Jianghe smiled mysteriously.

"Okay, I'll pass it on to you. Li Xianden nodded.

"You go to work, I still have something to do, I won't bother you in the afternoon, and I will leave the patent application to you." "The Chu River channel.

"Okay, you go get busy, do you want to use the car?"

"No, I have my own car, and if I can in the evening, we can have a meal together. Chu Jianghe said and left Li Modern's company. (To be continued.) )
