In the office, Zhao Guoyang and Sandro chatted happily.
The two quickly agreed on a salary.
And the treatment offered by Zhao Guoyang to the graduate students brought by Sandro has also been highly recognized by the other party.
After he finished speaking, Sandro promised on the spot that he would be able to bring at least seven students to the "Xingtai International" side.
Such a result made Zhao Guoyang very satisfied.
You must know that the seven people brought by Sandro are all top students in industrial design at McGill University.
With a little bit of finesse, there is a chance to become one of the world's leading designers in the future.
Such people can recruit seven at once, which is a very surprising result for any company that makes a living from design.
After determining the time when Sandro and the doctors came to China, Zhao Guoyang mentioned his "high-speed railway project" to Sandro and exchanged some technical problems with him.
Zhao Guoyang didn't want to test the other party, but just wanted to give this Sandro professor a research direction, so that he could start preparing in the near future.
After listening to Zhao Guoyang's story, Sandro nodded with relief: "I know about the high-speed railway project." ” "We don't have a similar rail system in Canada, though.
We have studied both the GV railway system and the ICE railway system in Germany.
No stranger to this."
When Zhao Guoyang heard this, he smiled and stretched out his hand to make a "please" gesture and said, "Mr.
Sandro knows something about this, that's great." ” "The high-speed railway system is my principle, and we have a team dedicated to the study of this aspect here at Xingtai International.
In addition, I may have to go to Bombardier in the next two days to discuss cooperation. ” "I would like you to tell us more about the design of the trains running on the high-speed railway, as well as the knowledge of related aspects."
Sandro sighed and said lightly: "According to the technical analysis, the high-speed railway train can be broken down into several parts: head shape, bogie, car body, traction control system, etc.
These parts are designed separately and finally combined into a single train. ” Of course, Zhao Guoyang also understands these basic analyses.
He nodded, and then began, "Mr.
Sandra is right.
This high-speed railway train is not much different from ordinary trains in terms of structure.
The only difference is in the appearance. ” "I don't know if Mr.
Sandro has any high opinions in this regard."
Listening to Zhao Guoyang's understatement, Sandro knew that the other party was very good at studying this.
He hurriedly said, "Mr.
Zhao, it's a coincidence.
I used to give homework to students on the design of this high-speed train as a project."
"At the beginning, I analyzed for you in this way: in terms of the design of high-speed trains, I was going to use the method of segmented design to arrange the tasks."
"Among them, the design of the head is entrusted to the head design supervisor; The design of the body is designed by the body supervisor and his department; The bogie is designed by a special steering department; The traction control system and power are designed by a separate power department. ” Sandro said brightly: "After this distribution, there will be no difficulties between 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, the teacher is the teacher, and in these three words, the design of the high-speed railway train is broken down into detail.
If you really use the teacher's design method, then the design of the entire train part will be very clear.
The design tasks of various departments will not be too heavy.
Compared with Isabella and Olivia's successive jaws, Zhao Guoyang seemed much calmer.
He touched his chin, as if he wanted to speak.
Noticing his action, Sandro knew that Chairman Zhao had some different opinions.
He smiled disappreciatively and said, "Mr.
Zhao, what I just said is just a consideration for assigning homework, and I haven't really practiced it."
In terms of details, there are definitely still imperfections.
If you have anything to say, just say it."
After Sandro finished speaking, Zhao Guoyang nodded with relief: "Mr.
Sandro is fast and fast-talking, which is admirable."
"Actually, I don't think there's anything wrong with your idea.
This kind of detailed design is indeed very beneficial to improve design efficiency. ” "It's just that I don't think the categories that Professor Sandro just mentioned are detailed enough.
One or two departments should be added to better reflect that we are designing trains for high-speed railways. ” Sandro had also heard Isabella mention it before, saying that Chairman Zhao was very accomplished in technology.

Of course, Sandro would not doubt his own students' words.
However, what kind of powerful method this Chairman Zhao is, Sandro is not clear.
At this time, after listening to the other party's words, he said with interest: "Mr.
Zhao, what you said is very reasonable, please continue." ” Zhao Guoyang nodded with a "hmm", and continued to speak: "Professor Sandro, I think so.
Because we are designing a high-speed train, its speed is undoubtedly the top priority. ” "To achieve such speeds, you need to be different from ordinary trains in terms of appearance.
Ride comfort at high speeds in terms of its own weight, air resistance, and high-speed operation are all issues that our designers need to consider. ” "And just by the three departments you just categorized, you can't include all of these things."
After Zhao Guoyang's words came out, Olivia on the side blinked his eyes and asked suspiciously: "Mr.
Zhao, what you just said should also be classified into the power design department."
"Weight and air resistance, aren't they 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 it is the design of ordinary trains, what you said can be summarized as the power design department. ” "But in the design of high-speed trains, such categorization does not work" "Why is that?"
Olivia wondered.
Zhao Guoyang stretched out two fingers and explained: "Two reasons, first of all, we should all know why Professor Sandro just divided the two parts of the locomotive and the body into two departments for design, it is very simple, it is because of the importance of the design of the locomotive of high-speed trains."
"The front of ordinary trains, most of them, are very ordinary, that is, square.
However, such a design, if used in high-speed trains, is undoubtedly not up to par. ” Listening to Zhao Guoyang's analysis, Isabella was curious: "Mr.
Zhao, I am not very proficient in the design of trains, but I have personally sat 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 didn't understand the reason for this, but now that I hear you say that, I'm even more confused."
After listening to Isabella's words, Zhao Guoyang smiled and said: "There is nothing that can't be figured out, the design of the front of the TGV high-speed railway train in France is definitely not for the beauty of the shape." ” "As a simple example, let's recall what it would be like to walk in high winds."
When Zhao Qian heard this, she said: "Walking in the wind, it's hard to move forward an inch, I really can't remember the other experiences."
Zhao Guoyang smiled at Zhao Qian and prompted: "Just imagine, if you move forward in the wind, will your waist bend down, because in this way, it will make it much less difficult for you to move forward."
"Ah, yes, it seems to be like that," Zhao Qian said with her mouth covered.
Zhao Guoyang waved his hand at her, and then said: "Therefore, the design of the head of the high-speed train is not for the sake of good appearance, but for the train to run better."
This includes speed and comfort. ” "We should all know that the biggest obstacle to the movement of objects running at high speed is not their own weight, but the air" "Ah, I understand this, it's air resistance," Zhao Qian raised her hand and said.
Zhao Guoyang let out a "hmm" and continued: "That's right, air resistance is the main way that air has a negative impact on high-speed trains.
Under normal circumstances, when the speed of the train is increased by 3 times, the air resistance will be 9 times higher. ” "Of course, not only the 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, if we try to minimize the influence of air, it is a very important topic. ” After listening to Zhao Guoyang's story, everyone suddenly realized.
Indeed, if there is only one power design department in the design department, it will not be enough to cover all of these detailed issues.
This necessitates the addition of one or two additional departments to study the effects of air on trains.
Sandro, who had not spoken all the time, couldn't help but sigh at this time: "Mr.
Zhao, I can be regarded as convinced of you."
Your understanding of high-speed train design is so deep" Zhao Guoyang smiled humbly, and then said: "In addition to the influence of the air when the train itself is moving, we can't ignore the airflow changes caused by the staggered interplay of the two trains. ” "In fact, the design speed of international high-speed trains is almost close to 350 kilometers per hour, which is equivalent to the speed of low-speed cruising of aircraft."
