King of Industry

  Chapter 961, Mr. Zhao please explain in detail

  After leaving the office, Zhao Guoyang went straight to the "Automobile and Motor Vehicle New Technology Research Institute".

  In a closed room at the innermost part of the research institute, Zhao Guoyang met a group of technicians from "Bombardier Rail Vehicle Design and Manufacturing Group Corporation".

  Out of the importance attached to "Xingtai International Foreign Trade Company" and respect for Zhao Guoyang himself, the several technical consultants sent by "Bombardier" this time are all elite-level figures.

First of all, needless to say, the leader, Mr. Barosh, the deputy director of the technical department of "Bombardier Rail Vehicle Design and Manufacturing Group Corporation" and an expert in rail vehicle design, is a technical leader in any rail vehicle design company. human figure.

  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 SJ.

  Of course, both Baros and Durant respect Zhao Guoyang very much.

  The two of them saw the magic of Mr. Zhao on the first day they came to SJ City and "Xingtai International".

   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 is simply amazing.

   What's even more exaggerated is that when the other party was designing this subway, he was still splitting his mind, and at the same time struck up a conversation with the two of them.

  With such a level, even a character like Barosh is a little frightened to watch.

  Because of the affirmation of Zhao Guoyang's design level, the team that "Bombardier" came to support was completely open to him and the entire technical department of "Xingtai International" in terms of design.

  The reason is very simple. Chairman Zhao's design may be a level higher than those of his own people.

   Rather than cherishing oneself and being a villain in vain, it is better to share design resources with the other party generously.

  Maybe, you can learn something from the other party's design ideas.

  Seeing Zhao Guoyang coming over at this time, the entire group of "Bombardier" showed joy.

Barosh, who was explaining his train of thought to his subordinates, stood up first, and extended his hand to Zhao Guoyang to invite him: "Mr. Design, I am a little ignorant. In this theory, you are an expert, much better than me, and I will trouble you to give them a class and help me make sense of them!"

  Barosh's words naturally have an element of humility in it. Although he mainly studies industrial design, how can he be weak in the theoretical knowledge of trains?

  The reason why he asked himself to do this explanation at this moment is nothing more than to see what level he is in theory.

   Zhao Guoyang didn't think there was anything wrong with Barosh's temptation.

   After all, since everyone is cooperating, it is a good thing to get to know each other better.

   Moreover, among the students that Barosh brought over, some of them didn't think much of the technicians of their own "Xingtai International". I took this opportunity to let them understand the situation.

  Thinking of this, Zhao Guoyang shrugged his shoulders and said, "It's impossible to talk about class, let's communicate with each other."

  Seeing that Zhao Guoyang agreed, Barosh was overjoyed.

He looked at one of his students Farmar with a smile, pouted and said: "Famar, didn't you have a lot of questions to ask just now? Nuo, Chairman Zhao is here. What do you not understand? Just ask him for advice!"

  After hearing this, Farmer nodded repeatedly and said, "Great, teacher. I'm a little confused about the design of the suspension system of the subway train. I would like to ask Mr. Zhao to explain it to me in detail!"

Hearing this, Zhao Guoyang nodded indifferently and said, "Okay, I still know a little bit about this, so let's give a brief account to Farmar. There are some inaccuracies, Mr. Barosh, Mr. Durant, you two can correct me at any time!"

  After hearing Zhao Guoyang's modest words, the three students Farmer, Kardashian, and Tristan just looked at me and I looked at you, showing meaningful smiles.

  Obviously, in the eyes of the three students of Barosh, Zhao Guoyang was obviously timid, afraid that what he said was inaccurate, so he was vaccinated in advance.

"The teacher has been touting how superb the technical level of Chairman Zhao is. It seems that apart from being better at using 3D software, he doesn't necessarily have any skills!" .

   Of course, Zhao Guoyang couldn't hear the slander of this Kardashian classmate.

  He cleared his throat, and then slowly explained his understanding of the suspension system.

   "The few present here are experts and masters in rail trains. They should know the structure and parameters of the bogie suspension system, and the importance to the smooth running of trains."

   "I think Mar, Kardashian, and Tristan should know about this knowledge when they were in school."

  After listening to Zhao Guoyang's narration, the three students nodded at the same time to express their approval.

  Zhao Guoyang touched his nose, and then said: "Since everyone knows the importance of the bogie suspension system, you should also know that it is usually composed of elastic components and shock absorbers?"

   What Zhao Guoyang said is the common sense of the train suspension system, so there is no mistake.

  After listening to his story, Farmer, Kardashian, and Tristan agreed with each other, but they all disagreed in their hearts.

  Obviously, in the eyes of the three of them, Zhao Guoyang's speech was a bit harsh.

   "It doesn't look like there's anything to do? I was talking about it before!" Kardashian puffed out her chest and thought disdainfully.

  Although Farmer and Tristan were not as obvious as Kardashian, there was 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."

   "The first point is the static deflection value of the elastic element; the second is the damping rate value of the shock absorber."

  Zhao Guoyang talked eloquently: "When designing the suspension, we need to design the static deflection value of the spring as large as possible. In this case, it is very helpful to reduce the natural frequency of the vibration system."

"But in terms of damping rate value, we should pay attention to it. Too large damping rate value and small damping rate value are not conducive to operation. Among them, there is an optimized range. This range is different from other suspension systems. The parameters are closely related."

   "Therefore, how to choose the damping rate value can only be obtained through detailed analysis of the vibration theory of the bogie suspension system!"

  After Zhao Guoyang said this, the five people in the room were shocked.

  Baros and Durant were better off, after all, they knew from the beginning that Chairman Zhao was highly skilled.

   But Farmer and Kardashian were completely confused.

  Originally, after Zhao Guoyang told the story without pain or itching at the beginning, they still vaguely felt that this young man was not very good.

   Who knew that within a few minutes, the other party suddenly changed his face, making the three of them dumbfounded.

  Indeed, although Zhao Guoyang’s narration does not seem to have much content, it is all the key and essence of suspension system design.

  Although these theoretical analyses, Kardashian and the others also learned it when they were in school.

  But it is absolutely impossible to speak out easily anytime and anywhere like Zhao Guoyang.

  What's the matter, 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 a "sorry" gesture and said: "Student Kardashian, can you please let me operate the computer?"

   "Ah..." Kardashian was taken aback, and immediately stood up blushing and said, "Mr. Zhao, use it!"

  Zhao Guoyang smiled slightly, sat in front of the computer, pointed to a half-formed design plan in front of him, and started his own explanation.

   "Just now I said that the selection of the damping rate value requires an in-depth analysis based on the vibration theory of the bogie suspension system. Next, I will give you a little demonstration."

  Pointing to the three-dimensional view in front of him, Zhao Guoyang calmly explained: "First, let's take a look at how to analyze the running stability."

"As the name suggests, running stability refers to the vibration balance of the running part and the reflection of passengers inside the vehicle. It will be reflected in the vibration acceleration and stability index of all lines and speeds during train operation... and in this regard, it is There is a formula, and I think Mr. Baros and Mr. Durant should be very clear about it."

   The meaning of Zhao Guoyang's words is somewhat obvious.

  He is saying that Baros and Durant can keep pace with him in theory in this regard.

  But the three of Kardashian are not enough.

   Kardashian and the three of them are all smart people, so they naturally heard the implication of Chairman Zhao's words, and they were naturally a little upset.

  But after calming down, the three of them shook their heads in frustration.

   Indeed, Chairman Zhao is right, the three of them are really lacking in this aspect.

  Seeing that the emotions of these three people calmed down quickly, Zhao Guoyang continued to talk: "Okay, we're done talking about the stability of operation, let's discuss the stability of operation again!"

  Hearing this, Kardashian stuck out her tongue and asked embarrassingly, "Mr. Zhao, isn't smooth running and stable running the same thing?"

   Farmer and Tristan also had the same doubts. They looked at each other and nodded repeatedly.
