After coming out of the office, Zhao Guoyang went straight to the "New Technology Research Institute of Automobile and Motor Vehicles".
In a closed room in the innermost part of the institute, Zhao Guoyang met several technicians from the "Bombardier Rail Vehicle Design and Manufacturing Group".
Out of the importance of "Xingtai International Foreign Trade Company" and respect for Zhao Guoyang himself, several technical consultants sent by "Bombardier" this time are all elite-level figures.
First of all, it goes without saying that the leader is Mr.
Barosh, deputy director of the technical department of "Bombardier Rail Vehicle Design and Manufacturing Group" and an expert in rail vehicle design, this is the person who should be the technical leader of any rail vehicle design company.
Secondly, Durant, the senior director of the technical department and the project manager, is also a well-known figure.
With such two heavyweight technical masters in charge, it can be seen that "Bombardier" attaches great importance to the subway project in Songjiang City.
Of course, whether it is Barosh or Durant, they have great respect for Zhao Guoyang.
On the first day they came to Songjiang City and came to "Xingtai International", these two people saw the magic of this Mr.
Zhao.
Under the gaze of the two of them, Mr.
Zhao used UG 3D software to draw a design sketch of a subway within 20 minutes, which was simply amazing.
What's even more exaggerated is that when the other party was designing this subway, he was still divided into two parts, while talking to the two of them.
At such a level, even a character like Barosh is a little frightened to watch.
It is precisely because of the affirmation of Zhao Guoyang's design level that the team that "Bombardier" came to support is completely open to him and the entire technical department of "Xingtai International".
The reason is very simple, Chairman Zhao's design may be a grade higher than the design of his own people.
Instead of cherishing oneself and being a villain, it is better to share design resources with each other generously.
Maybe you can learn something from the other person's design ideas.
At this time, seeing Zhao Guoyang coming, the group of "Bombardier" was overjoyed.
Barosh, who was explaining his thoughts to his subordinates, was the first to stand up and stretched out his hand to Zhao Guoyang to invite: "Mr.
Zhao, you came just in time."
My students are a little ignorant about the design of the subway train suspension.
In terms of theory, you are an expert, much better than me, and you have to trouble you to teach them a lesson and help me explain a few of them."
There is naturally an element of modesty in Barosh's words, although he mainly studied industrial design, but in terms of theoretical knowledge of trains, how could he be weak At this time, the reason why he asked himself to do this explanation was nothing more than to see what level he was at in theory.
Regarding Barosh's temptation, Zhao Guoyang didn't think there was anything bad.
After all, since everyone is cooperating, it is a good thing to get to know each other better.
Moreover, among these students brought by Barosh, a few of them did not think much of the technicians of their own "Xingtai International", and they took this opportunity to let them know the situation.
Thinking of this, Zhao Guoyang shrugged his shoulders and said, "I can't talk about it in class, let's communicate with each other." ” Seeing that Zhao Guoyang agreed, Barosh's face was happy.
He looked at one of his students, Famar, with a smile, and said, "Famal, didn't you have a lot of questions to ask just now, Chairman Zhao is here, if you don't understand anything, just ask him for advice."
Hearing this, Famar nodded again and again, "Great, teacher."
I have some confusion about the design of the suspension system of the subway train, and I would like to ask Mr.
Zhao to tell me in detail."
When Zhao Guoyang heard this, he nodded disappreciatively and said, "Yes, I still know a little bit about this, so let's give a brief explanation to Farmar."
If there is any inaccuracy in what you said, Mr.
Barosh and Mr.
Durant, you can correct it at any time."
Listening to Zhao Guoyang's modest words, the three students, Famar, Kardashian, and Tristan, showed a meaningful smile when you look at me and I look at you.
Obviously, in the eyes of the three masters of Barosh, Zhao Guoyang was obviously timid, afraid that what he said would be inaccurate, so he took the vaccination in advance.
"The teacher has always touted how superb the technical level of this Chairman Zhao is.
It seems that in addition to using 3D software better, he doesn't necessarily have any skills" Kardashian, who has an ordinary appearance but an explosive figure, muttered secretly in her heart.
Of course, Zhao Guoyang can't hear the slander of this Kardashian classmate.
He cleared his throat and slowly recounted his understanding of the suspension system.
"Several of you here are experts and experts in rail trains, and they should know the structure and parameters of the bogie suspension system, and the importance of the smooth operation of the train."
"I think that Mar, Kardashian, and Tristan should have understood this knowledge when they were in school."
After listening to Zhao Guoyang's remarks, the three students nodded at the same time in approval.

Zhao Guoyang touched his nose, and then said: "Since everyone knows the importance of the bogie suspension system, it should also be known that it is usually composed of two parts: elastic elements and shock absorbers."
What Zhao Guoyang said is the common sense content of the train suspension system, and it will naturally not be wrong.
Listening to his story, Famar, Kardashian, and Tristan agreed with each other, but they were all a little disapproving.
Obviously, in the eyes of the three of them, Zhao Guoyang's speech was somewhat stubble.
"It doesn't look like there's anything dry, and I was babbling before," Kardashian said with a disdainful thought.
Although Famar and Tristan are not as obvious as Kardashian, there is already some mockery in their eyes.
Zhao Guoyang didn't seem to see the disdain of the other three, he said to himself: "If you want to do a good job in the design of the suspension system, you must master two important parameters." ” "First of all, the first point is the static deflection value of the elastic element; Secondly, it is the damping rate value of the shock absorber. ” Zhao Guoyang said: "When designing the suspension, we need to design the static deflection value of the spring as large as possible.
In this way, it is very helpful to reduce the natural frequency of the vibration system. ” "But in terms of damping rate values, you have to pay attention.
Both too large damping rate values and large damping rate values are not conducive to operation.
Among them, there is an optimization scope.
This range is closely related to the other parameters of the suspension system. ” "Therefore, how to choose the damping rate value can only be obtained through a detailed analysis of the vibration theory of the bogie suspension system."
After Zhao Guoyang's remarks came out, the five people in the room were all stunned.
Barosh and Durant are better, after all, they knew from the beginning that Chairman Zhao had a superb level of technology.
But the three of Famar and Kardashian were completely confused.
Originally, after Zhao Guoyang told the story at the beginning, they still vaguely felt that this young man was not very good.
Who knew that it was only a few minutes before the other party suddenly changed his face, directly making the three of them dumbfounded.
Indeed, although Zhao Guoyang's remarks do not seem to have much content, they are all the key and essence of the suspension system design.
Although these theoretical analyses were learned, Kardashian had learned them when they were in school before.
But it is absolutely impossible to be like Zhao Guoyang and easily say it anytime and anywhere.
Anyway, they have to go back and check the information before they dare to say this.
Zhao Guoyang ignored the astonishment of the three, he gestured to Kardashian, made an "sorry" gesture and said, "Kardashian, please let me operate the computer?"
"Ah" Kardashian was taken aback, and then quickly stood up with a red face and said, "Mr.
Zhao, you use it" Zhao Guoyang smiled slightly, sat in front of the computer, pointed to a semi-formed design plan in front of him, and began his own explanation.
"As I said just now, the selection of the damping rate value should be analyzed in depth through the vibration theory of the bogie suspension system.
Now, I'll show you a little bit of it. ” Pointing to the three-dimensional view in front of him, Zhao Guoyang calmly explained: "First of all, let's take a look at how this operation smoothness should be analyzed. ” "As the name suggests, running smoothness refers to the vibration balance of the running part and the reflection of the passengers inside the vehicle.
It will be reflected in the vibration acceleration of the train operation, all lines and speeds, and the stability index and in this regard, it has a formula, I think Mr.
Baroshe, Mr.
Durant should be very clear. ” The meaning of Zhao Guoyang's words is somewhat obvious.
He is saying that Barrosh and Durant can theoretically go toe-to-toe with him in this regard.
But the three of them are not enough.
Kardashian and the three of them are all smart people, so they naturally heard the meaning of Chairman Zhao's words, and they were naturally a little unhappy in their hearts.
But after calming down, all three shook their heads in frustration.
Indeed, Chairman Zhao is right, the three of them are really lacking in this regard.
Seeing that the emotions of these three people quickly calmed down, Zhao Guoyang then continued: "Okay, that's it, let's talk about the stability of the operation."
Hearing this, Kardashian stuck out her tongue and asked, "Mr.
Zhao, isn't this running smoothly and running stable the same thing?"
Falmar and Tristan had the same doubts, and they looked at each other and nodded their heads in agreement
