King of Industry

  Chapter 949 Speed ​​is undoubtedly the top priority

  In the office, Zhao Guoyang and Sandro had a pleasant chat.

  The two quickly reached an agreement on the issue of salary and treatment.

   And Zhao Guoyang's treatment for the postgraduate students brought by Sandro has also been highly recognized by the other party.

  After he finished speaking, Sandro promised on the spot that at least seven students could be brought to the "Xingtai International" side.

   Such a result made Zhao Guoyang very satisfied.

   You know, the seven people that Sandro led were all top students in industrial design from McGill University.

  As long as you give a little advice, you will have the opportunity to become a world-class designer in the future.

  Seven people like this can be recruited at once, which is a very surprising result for any company that makes a living from design.

  After confirming the time for Sandro and the doctors to come to China, Zhao Guoyang and Sandro mentioned the "high-speed railway project" he was working on, and exchanged some technical issues with him.

   Zhao Guoyang didn't want to test the other party, but just wanted to give this Professor Sandro a research direction so that he could start preparing in the near future.

  After listening to Zhao Guoyang's narration, Sandro nodded in relief and said, "I know about the high-speed railway project."

   "Although we do not have a similar railway system in Canada. We have studied the 'TGV railway system' in France and the 'ICE railway system' in Germany. We are no strangers to this!"

   Zhao Guoyang heard the words, smiled and stretched out his hand and made a "please" gesture: "Mr. Sandro knows about this, that would be great."

   "I have the principle of the high-speed rail system. In this regard, we at Xingtai International have a team dedicated to research. In addition, I may go to Bombardier to discuss cooperation matters in the next two days."

   "On the contrary, I hope you can talk more about the design of trains running on high-speed railways and related knowledge..."

Sandro let out a "huh", nodded lightly and said: "According to technical anatomy, a high-speed railway train can be decomposed into several parts: head shape, bogie, car body, traction control system, etc. These parts are designed separately, In the end, the whole is combined into one train."

   Zhao Guoyang certainly understands these basic analysis.

  He nodded, and then said: "Mr. Sandra is right. The structure of this high-speed railway train is not much different from ordinary trains. The only difference is in appearance."

   "In this regard, I wonder if Mr. Sandro has any insight?"

  After hearing Zhao Guoyang's understatement, Sandro knew that the other party had studied it very well.

  He quickly said: "Mr. Zhao, it's a coincidence. The design of this high-speed train, I used to be a subject before and assigned homework to the students alone!"

   "At the beginning, I analyzed it for everyone in this way! In terms of the design of high-speed trains, I plan to adopt a segmented design method to assign tasks."

"Among them, the design of the head is handed over to the head design supervisor; the design of the body is designed by the supervisor of the body and his department; the bogie is designed by a special steering department; the traction control system, power , it is designed by another power department.”

  Sandro said brightly: "After this allocation, there will be no difficulty in paralleling multiple departments among several departments. This is very helpful for improving the efficiency of the overall design."

  After listening to Sandro's statement, Isabella and Olivia on the side nodded in agreement.

  However, a teacher is a teacher. In a few words, the design of the high-speed railway train is broken down into detail.

  If the design method of the teacher is really adopted, then the design of the entire train part will be very clear.

  The design tasks of each department will not be too heavy.

  Compared to the repeated nods of Isabella and Olivia, Zhao Guoyang seemed much calmer.

  He touched his chin, seemingly hesitant to speak.

   Noticing his action, Sandro knew that Chairman Zhao had some different opinions.

He smiled indifferently and said: "Mr. Zhao, what I just said is just a consideration for assigning homework, and I haven't really practiced it. There must still be imperfections in the details. If you have any Just mention it, just say it!"

  After Sandro finished speaking, Zhao Guoyang nodded in relief and said, "Mr. Sandro speaks quickly, which is admirable!"

   "Actually, I don't think there is any major problem with your idea. This kind of split and detailed design is indeed very beneficial to improve design efficiency."

"It's just that I don't think the categories mentioned by Professor Sandro are exhaustive enough. One or two departments should be added to better reflect that we are designing trains for 'high-speed rail'. "

  Sandro also heard Isabella mention it before, saying that Chairman Zhao is very accomplished in technology.

   Of course, Sandro would not doubt what his students said.

  However, Sandro does not know how powerful Chairman Zhao is.

  Hearing what the other party said at this time, he said with interest: "Mr. Zhao, what you said is very reasonable, please continue."

  Zhao Guoyang nodded with a "huh" and continued to speak: "Professor Sandro, I think so. Because we are designing a high-speed train, its speed is undoubtedly the most important thing."

  “To achieve such a speed, in addition to the difference in appearance from ordinary trains. The weight, air resistance, and ride comfort under high-speed operation are all issues that need to be considered by our designers.”

   "But just relying on the three departments you just classified, it is impossible to include all these things!"

  After Zhao Guoyang said these words, Olivia blinked and asked suspiciously: "Mr. Zhao, what you just said should also be included in the power design department?"

   "Aren't weight and air resistance all factors that affect power output? This is nothing special!"

After Olivia finished speaking, Zhao Guoyang shook his head solemnly and explained: "Olivia, you are wrong! If you are designing ordinary trains, what you said can be summarized as power design department to consider."

   "But in the design of high-speed trains, such classification will not work!"

   "Why is that?" Olivia asked curiously.

Zhao Guoyang stretched out **** and explained: "Two reasons! First of all, we should all know why Professor Sandro divided the two parts of the front and the body into two parts for design just now? It's very simple, because the high-speed train The importance of front design!"

   "Most of the fronts of ordinary trains are very ordinary and square. However, if such a design is used on high-speed trains, it will undoubtedly not pass the test."

  Listening to Zhao Guoyang's analysis, Isabella said curiously: "Mr. Zhao, I am not very proficient in train design, but I have personally ridden on the 'TGV high-speed railway' in France."

"Indeed, as you said, the shape of the head of this 'TGV high-speed railway' train is very special. I have never been able to understand the reason for this... Now that you say that again, I am even more confused !"

  After listening to Isabella's words, Zhao Guoyang smiled and said: "There is nothing unreasonable about this. The design of the front of the 'TGV high-speed railway' train in France is definitely not for the beautiful shape."

   "To give a simple example, let's recall what kind of experience it would be to walk in a strong wind?"

   Zhao Qian heard the words, and said in a low voice: "Walking in the strong wind, is it difficult to move forward? I really can't remember other experiences..."

  Zhao Guoyang smiled slightly at Zhao Qian, and reminded: "Just imagine, if you are going forward in a strong wind, will your waist bend down? Because this will make it much easier for you to move forward!"

   "Huh? That's right, it seems to be true!" Zhao Qian said while covering her mouth.

  Zhao Guoyang waved to her, and then said: "So, the design of the head of the high-speed train is not for the appearance, but for the train to run better. This includes speed and comfort."

  "We all should know that the biggest obstacle to the movement of a high-speed object is not its own weight, but the air!"

   "Ah, I understand this, it's air resistance!" Zhao Qian raised her hand and said.

Zhao Guoyang gave a "hmm" and continued: "Yes, air resistance is the main way that air negatively affects high-speed trains. Under normal circumstances, when the speed of the train increases by three times, the air resistance will increase by nine times. "

   "Of course, it is not only air resistance, but also the influence of air on high-speed trains, as well as aerodynamic noise, tunnel micro-pressure waves, train surface pressure waves and many other aspects."

   "In fact, in the state of high-speed operation, the power output of the train is almost consumed in the confrontation with the air. Therefore, when we design, it is a very important issue to minimize the impact of the air."

   After listening to Zhao Guoyang's narration, everyone suddenly realized.

  Indeed, if there is only one power design department in the design department, it is not enough to include all these detailed topics.

   This would require an additional department or two dedicated to the study of the effects of air on trains.

  Sandro, who had been silent for a long time, couldn't help sighing at this moment: "Mr. Zhao, I've convinced you. Your understanding of high-speed train design is really too deep!"

  Zhao Guoyang smiled modestly, and continued: "In addition to the air influence when the train itself is running, we can't ignore the airflow changes when two trains cross."

   "In fact, the design speed of high-speed trains in the world is almost 350 kilometers per hour, which is already equivalent to the low-speed cruising speed of an airplane..."
