King of Industry - Chapter 962

  Chapter 962 Why is he so monstrous?

  In the room, after hearing Kardashian’s question, Zhao Guoyang smiled and shook his finger.

   “Running stability and running stability are two different things. Running stability refers to the comfort of walking; while running stability focuses on the safety of walking.”

   “The reason why there is a parameter of running stability is mainly because of the lateral self-excited vibration problem that may occur when the train runs at high speed in a straight line. Usually, we call it snake stability.”

   “The stability of the snaking not only affects the stability of the train, but may also lead to derailment and endanger the safety of operation. Therefore, we must focus on the analysis of the critical speed of the snaking…”

  Listening to Zhao Guoyang’s narration, the two senior experts in the studio nodded in agreement.

“Mr. Zhao is very good! There is a close relationship between the critical speed of the snake and the derailment coefficient of the train. In this regard, Durant and I are also planning to talk to Kardashian and the others!” Barosh said with emotion Said.

Durant on the side heard the words, and echoed repeatedly: “Yes, yes, yes, Mr. Zhao, Minister Barosh and I are much more relaxed, and we can learn a lot… You can continue to talk, we are all ears! “

  Durant’s words are not flattery.

  In fact, like Baros, he paid more attention to the exterior design of the train.

   It’s not that he doesn’t understand these theoretical studies, but that he doesn’t need to study them in detail.

   After all, for a company as large as “Bombardier Rail Vehicle Design and Manufacturing Group Corporation”, the following division of labor must be very detailed.

  This kind of theoretical analysis must be done by a special person.

  After listening to Durant’s invitation, Zhao Guoyang nodded with a smile, and continued to describe some technical analysis he knew.

  He rubbed his chin and said: “It is different from ordinary open railway trains. The passability of subway trains is more complicated. In this case, when we design trains, we must pay attention to the passability of this curve.”

Hearing this, Kardashian raised her chest and raised her hands and said: “Mr. Zhao, I know this. The curve passing performance refers to the unfavorable static and dynamic forces on the track and bogie when the train passes through the curved road. And The possibility of train derailment under the condition of improper wheel and track forces.”

Upon hearing this, Zhao Guoyang nodded approvingly and said, “Student Kardashian is right, that is the meaning of curve passing performance. Before designing, we need to calculate the curve passing performance parameters. There are about three items. Rail superelevation, unbalanced centrifugal force, and curve speed limit…”

  Zhao Guoyang’s detailed narration directly convinced the three students.

  After he talked eloquently, Kardashian showed an amazed expression and said: “Mr. Zhao, Mr. Barosh is really not flattering. Your theoretical level is really admirable.”

   “Yes, what Kardashian said is true!” Farmer and Tristan also nodded in agreement.

Zhao Guoyang seemed very calm, he smiled, opened a rough analysis form on the computer, and said with a smile: “In terms of design, Mr. Baros and Mr. Durant are in charge, so there must be no problem. “

“For my side, I will roughly explain the train dynamics simulation analysis steps to Kardashian and you. When you assist the two teachers in the design, you can try to substitute these dynamics simulation analysis into it. The improvement of your practical analytical ability is very helpful.”

  After Zhao Guoyang said this, Kardashian, Farmer, and Tristan looked at me and I looked at you, all of them were surprised.

   On the other side, Baros and Durant were equally overjoyed, and they almost moved a stool to sit down and be melon-eaters.

  Zhao Guoyang “scraped” on the computer, called up a 3D model from the UG 3D program, and then started his own narration.

   “To do vehicle dynamics simulation analysis, you must first establish a vehicle system mechanics model and its mathematical description. In three-dimensional analysis, we call it ‘modeling’!”

  Listening to Zhao Guoyang’s serious explanation, the three students nodded repeatedly.

   “After the modeling is completed, we need to provide relevant system parameters. These parameters include vehicle geometry, mass, suspension parameters, etc.!”

   “The geometric parameters include such data as wheel diameter, bogie wheelbase, and bogie center distance;”

  When Zhao Guoyang said this, Farmer responded repeatedly: “Understood, Mr. Zhao. The geometric parameters are the appearance data. Then the quality parameters are obviously the quality of each component of the vehicle?”

After hearing this, Zhao Guoyang smiled and shook his head: “What you said is not comprehensive enough. In fact, quality parameters include not only the quality of parts, but also the quality of motors, car bodies, frames, gearboxes, and wheel-to-axle components.” The mass and moment of inertia of parts such as boxes. These cannot be expressed by simple weight.”

  Famar couldn’t help but blush when he heard this.

  Indeed, compared to Mr. Zhao’s erudition, he was a bit too overconfident just now in rushing to speak.

Zhao Guoyang smiled and patted him on the shoulder to show comfort, and then said: “As for the suspension parameters, this is more complicated. It includes the positioning stiffness and suspension stiffness of the first and second series. In addition, it also includes the first and second series. The damping characteristic curve of the second series.”

   Listening carefully to Zhao Guoyang’s analysis, Tristan couldn’t help asking: “Mr. Zhao, besides these three system parameters, are there other parameters that need to be analyzed?”

  Zhao Guoyang gave a “hmm” and said affirmatively: “Of course, these other parameters also include various geometric states when the wheels and rails are in contact, the taper of the contact point, and the change curve, etc.”

  Hearing this, Kardashian couldn’t help but sighed: “Mr. Zhao, there are so many steps in this vehicle dynamics simulation analysis. Just the few of us, I’m afraid we can’t handle it?”

  Zhao Guoyang smiled and said: “This is natural! In fact, we have a special person at Xingtai International to do the simulation and analysis of vehicle dynamics.”

“Of course, I know that your ‘Bombardier Rail Vehicle Design and Manufacturing Group’ also has the same research unit. But the subway system in our city of SJ is inconsistent with your domestic railway system in Canada. It is obviously not the same to copy your simulation analysis. appropriate.”

“Therefore, this time I invited Mr. Baros and Mr. Durant over here, mainly to ask them to help design the appearance of the train. As for the technical things such as vehicle dynamics simulation analysis, our people will do their best to assist you. .”

Although Zhao Guoyang didn’t make it very clear, the meaning is undoubtedly very clear, that is, to ask Kardashian, Farmer, and Tristan to be more like his “Automobile and Motor Vehicle New Technology Research Institute” study.

Although Kardashian has big breasts, she is not brainless. After hearing what Mr. Zhao said, she blushed and nodded: “What Mr. Zhao said is true! We still need to analyze the specific situation. In this regard, we After the three, you must communicate more with your company’s technical personnel and ask them for advice!”

  Seeing how knowledgeable she is, Zhao Guoyang nodded in satisfaction and said, “It’s not worth asking for advice. Anyway, let’s learn from each other!”

   Kardashian, Farmer, and Tristan have already worshiped Zhao Guoyang to the extreme at this moment, and they naturally obeyed everything he said.

  After listening to Zhao Guoyang’s point, the three of them nodded again and again, saying that they would definitely get along well with Huaxia’s technicians.

   Seeing that his three students had changed from their previous arrogance, Barosh let go of his worries.

   Turning his head to look at Zhao Guoyang, the Minister of Technology felt a burst of emotion.

  Speaking of which, Mr. Zhao and his three students seem to be about the same age. Why are they so monstrous?

   Listening to what he just said, it is clear that he said it at his fingertips without any preparation.

   It’s even more frightening to play as you please!

  Zhao Guoyang didn’t know the emotion in Barosh’s heart. After teaching Kardashian and the others, he shook hands with Barosh and Durant and said goodbye with a smile.

  Looking at his back, Baros and Durant looked at each other, full of emotions.

“Teacher, Mr. Durant, what is the background of Chairman Zhao? Looking at his age, he seems to be only twenty-four or five years old. How can he know so much better than the three of us? Could it be that Huaxia’s school is better than ours? Should it be earlier? He has already graduated with a Ph.D. at the age of twenty-four or five?” Kardashian asked unwillingly.

   “Not a doctor’s degree! As far as I know, this Chairman Zhao only has a bachelor’s degree.” Barosh said shaking his head.

   “What? Just a bachelor’s degree? How is that possible?” Farmar couldn’t help exclaiming.

  Barosh glanced at his disciple, shrugged and said, “That’s the truth, but I don’t know the specifics.”

   “If the three of you want to learn more about the situation, you might as well establish a good relationship with the technicians of ‘Xingtai International’, maybe you can gain something…”

  After listening to the teacher’s “trick”, Kardashian, Farmer, and Tristan’s eyes lit up.

“What the teacher said is right! Then let’s use our affinity for a while and see if we can let these researchers in Huaxia tell the story of Chairman Zhao!” Kardashian is full of confidence Said.

  Famar glanced sideways at her beautiful figure, then turned his head and winked at Tristan, all with a joking look on his face.

  Noticing the expressions of these two classmates, Kardashian pouted and said, “Hey, what kind of eyes are you two looking at? Don’t you doubt my ability?”

Hearing this, Tristan quickly waved his hand and said: “No, no, Kardashian, you misunderstood. The two of us thought that if you came out alone, it would definitely be easy to catch. Among the researchers in Huaxia, there are You are young and full of vigor. With you, a beautiful woman, taking the initiative to strike up a conversation, how can they hold back?”

   “Yes, yes, yes, what Tristan said is on point! Everyone knows the charm of our Miss Kardashian. I don’t believe it, the researchers of ‘Xingtai International’ can control it!”

  Kardashian didn’t care much about the teasing of these two guys. She snorted, turned her head proudly, and continued to fiddle with the data on the computer.
