On the podium, Zhao Guoyang said aloud slowly: "The role of the gear change operation mechanism is very clear to everyone here."

"It is an important mechanism used on motorcycles to control the separation and engagement of clutches, cut off and engage the power output of the engine, thereby achieving the smooth start and shifting functions of the motorcycle."

"Its composition mainly includes clutch handle, pull wire, separation rocker arm and other components."

"The stability of the gear change operation mechanism plays a crucial role in avoiding and reducing the impact on the engine and achieving stable and safe driving. Today, I would like to give you a brief discussion on this issue..."

Zhao Guoyang's speech pointed out the theme at the beginning, which made people couldn't help but look forward to it.

Off the stage, Antonio Ducati, the technical president of Ducati, nodded secretly when Zhao Guoyang spoke.

"Well, this young man from China seems to be not very old last year, but he should have a good understanding of the motorcycle industry. The entry point of his speech is very unique, which makes people shine..."

Not only Antonio Ducati, but also several industry big shots, including Suzuki Ke, Kawasaki Mi and Ke Zhijian, were also interested in Zhao Guoyang's speech, and they sat upright and stared at the stage.

In the corner, Sun Zhengxiao and Li Qinan noticed the attention on the faces of the big guys scattered there. After looking at each other, they were all a little stunned.

"Mr. Sun, what's going on?"

Li Qinan couldn't help but speak, "Just when I saw Mr. Ethanmel, the BMW company's speech, the big guys didn't pay so much attention. Why did they get more young people now, but they are more focused?"

Sun Zhengxiao was stunned when he heard this, tilted his head and thought for a long time, but he still couldn't figure out why.

At this moment, he could only tell the truth: "Mr. Li, I really don't know much about this. Could it be that this young man really has a few tricks?"

Li Qinan stared at Zhao Guoyang on the stage with blank eyes for a while, but he really couldn't see anything special about this young man.

He secretly complained in his heart: Could this boy named Zhao Guoyang be a direct relative of Mr. Li of the Ministry of Mechanical and Electronics Industry, or Mr. Li’s beloved disciple? Is he the newcomer he wants to promote this time?

Unable to understand, Li Qinan could only temporarily put aside the doubts in his heart and patiently continued to listen to Zhao Guoyang's story.

On the podium, Zhao Guoyang was talking and getting better.

After being reborn, this is not the first time he has spoken on such an important occasion.

How could there be any tension when facing these big guys in the industry in the audience?

On the contrary, after seeing Ducati, a company with full personality, sending important figures to participate in the exhibition, Zhao Guoyang's passion became even more uncontrollable.

"Just now, I told you about the importance of gear shifting control mechanisms for a motorcycle. The accuracy of movement is the primary prerequisite for ensuring the reliability of gear shifting of motorcycle engines."

Zhao Guoyang waved his hand and gestured: "Everyone here may also know that the gear change control mechanism has an important feature, which is that it is a nonlinear system, and the accuracy of its movement will fluctuate according to the allowable manufacturing error of structural parameters."

"Then, when we design, we face a serious problem. It is to ensure that the structural parameters have good processability, so that the distribution center of the system error is as close to the ideal value as possible, and the error dispersion range is as small as possible, so as to make the accuracy of the gear shifting control mechanism most stable."

Speaking of this, the attention of all the participants was completely attracted by Zhao Guoyang.

To be fair, Zhao Guoyang's opinion has proved to some extent his outstanding technical strength.

His definition of motorcycle gear change operation mechanism and his judgment of vehicle stability are very accurate.

Among the popular internationally-selling medium and large motorcycle brands, the best models sold are nothing more than those from Harley Davidson, Suzuki, Honda, and Yamaha.

Speaking of which, these cars are popular, in addition to ensuring quality, they also have their unique features in other aspects.

For example, Harley Davidson's cars often have domineering appearance and strong horsepower; Suzuki's cars focus on driving experience; Honda's engine is reliable.

But when it comes to smooth and round gear change, senior motorcycle enthusiasts will definitely choose Ducati's car.

It is no exaggeration to say that Ducati's accurate calculation of gear shift control mechanisms is the best in the motorcycle industry at present.

Its advantage has always been coveted by competitors in the same industry.

Therefore, when Zhao Guoyang was telling this, the bigwigs of several major companies in the audience suddenly felt energetic.

Suzuki Kei looked at Zhao Guoyang who was waving freely on the stage with bright eyes and murmured to himself: "Zhao... Guoyang, can you really tell me how to improve the accuracy of gear shift control mechanism movement?"

Compared to the muttering of the Suzuki Group boss, Kawasaki O's Kawasaki Co., Ltd. has already started to discuss with Aso Kiko around him.

"Xizi, do you think Zhao Guoyang can really point out the technology of the gear change control mechanism design that Ducati has hidden for so long?"

"Well, President, I think it's very likely!"

Aso nodded slightly and said, "Based on his existing analysis, I feel that this young man has really had very in-depth research on the gear change control mechanism."

"You will know this, just look at the expression of the Ducati company over there..."

Looking in the direction that Aso Kiko looked at, Kawasaki Ou saw the ugly look on Antonio Ducati's face as if he had eaten a fly.

There is no doubt that Zhao Guoyang's analysis on the stage made him feel bad.

On the Guangyang Group side, Ke Zhijian was also amazed at Zhao Guoyang's statement.

Although he doesn't know much about motorcycle technology, he still knows some important systems such as gear shift control mechanism.

The reason why Guangyang Group’s products cannot be sold in those major international brands is that there is some technical lack of gear shifting.

"Xiaodong, you really should learn from this Mr. Zhao!"

Ke Zhi couldn't help but speak to his son: "You are young and capable without showing off, this is beyond your reach..."

"Well, I understand, father." Ke Xiaodong agreed, secretly treating Zhao Guoyang as his goal in his heart.

Zhao Guoyang didn't know that he had become the center of discussion among several bigwigs in the audience, so he would continue his speech with emotion.

"Due to the allowable error of structural parameters, the degree of impact on system error varies depending on the values ​​of its structural parameters. Therefore, the core of stability design is to find this reasonable group of structural parameters."

"If you want to choose the best structural parameters of the variable speed control mechanism, I think you can construct a mathematical model to express the motion accuracy relationship of the variable speed control mechanism, and then formulate an evaluation index to measure stability. With the help of orthogonal tables and computers, this can be easily achieved..."

At this point in Zhao Guoyang's words, the big guys in the audience were no longer calm.

There is no doubt that everyone is an expert in the industry. Regarding the method of constructing mathematical models and formulating evaluation indicators mentioned by Zhao Guoyang, these big guys can judge their feasibility without thinking.

"Construct a mathematical model and formulate evaluation indicators..." Suzuki's brows stretched for the first time, and kept muttering these two sentences in her mouth.

"Awesome, it's so amazing!" Not far away, Kawasaki Mitsu couldn't help but speak after being stunned for a while.

A bright color flashed in Aso's eyes beside him, and a smile on his face "It's true".

After sighing, Kawasaki Yu turned his head and said to his assistant seriously: "Kiko, this Zhao Guoyang is a talent. We must find a way to bring us Kawasaki Co., Ltd.! Do you know!"

"Yes, President. I understand the importance of this Zhao Guoyang to our Kawasaki Co., Ltd."

Aso Kiko hesitated for a moment and continued, "But, the competition we face may also be very fierce..."

"Well, of course I know this!"

Kawasaki Mi's eyes were wandering around Suzuki Kei and BMW's Isanmeier, and said confidently: "However, if it's Kiko, you personally, I think our Kawasaki Co., Ltd. has a great chance of winning..."

Regarding President Kawasaki's optimism, Aso nodded reservedly and said nothing.

In fact, after seeing Zhao Guoyang's performance on the first day of the auto show with her own eyes, she had long since no doubt about his abilities.

What Aso Kiko wanted to know more at this time was what else could Zhao Guoyang say?

If anyone who was most excited after listening to Zhao Guoyang's speech at the scene must be Antonio Ducati.

Zhao Guoyang's understatement just now is exactly in line with Ducati's design philosophy in the gear change control mechanism.

Even what he said is "constructing mathematical models and formulating evaluation indicators" is exactly the same as the method Ducati uses now.

If this weren't in China, and Zhao Guoyang was too young, Antonio Ducati thought he might be a commercial spy who had been lurking in his company for many years.

"This... this guy is so amazing, right? How did he know the calculation method of our company? How could he come up with it himself?" Antonio Ducati murmured to himself.

Unlike Antonio Ducati, BMW's Ethanmeier said to Zhao Guoyang more about deep thought than shock.

Ethanmere is a technical background and has a double doctorate in the machinery manufacturing industry and automobile industry.

His level of motorcycle theoretical design may be the only one on site who is comparable to Antonio Ducati.
