Seeing Zhao Guoyang's calm and composed look, Liang Hongjun was secretly surprised, but he did not show any expression on the surface.

From the beginning to now, Liang Hongjun has been shocked by Zhao Guoyang's various behaviors, and at this time he has some adaptability to his words and deeds.

Seeing that this young man had no doubts when he heard the three words "bending beam car", Liang Hongjun knew that the other party must have known this new motorcycle.

A young man who studies mechanical manufacturing in a university actually knows the type of motorcycles so well, which shows that the other party must be a person who loves learning, studying, and knowledgeable.

In addition, Liang Hongjun noticed the highly technical article in "Made in China" that Zhao Guoyang was concerned about before, and his attention to this young man had far exceeded that of Ma Jian, the deputy factory director who came with him.

Wang Hongxi quickly took the frame diagram over and put it on the table.

Looking at this neat base picture drawn with a drawing pencil, Zhao Guoyang secretly exclaimed.

In the 1990s, computer use was just beginning, and domestic companies were simply rare.

Although the two-dimensional design software AUTOCAD was released in 1982, due to the fact that domestic computers have not been popularized, the Weiruan Windows system has not yet become famous, so AUTOCAD, the giant drawing software, is almost unknown in China at this time, let alone application.

During this period, most manufacturing companies used hand-drawing when making pictures, and Siyang Group was no exception.

This frame drawing is very neat and exquisite, and even with Zhao Guoyang's picky eyes, he cannot find any faults.

Of course, this drawing is just a three-view overall, which can only make people roughly see the outline of this frame.

If you want to actually try it out, it will be hundreds or even thousands of parts drawings.

Zhao Guoyang knew in his heart that only when the other party confirmed that his Hongda Machinery Factory had this production capacity, would he further contact him and come up with more parts drawings.

"Comrade Xiao Zhao, this is the frame diagram of the C100 curved beam car that our Siyang Group will soon put into mass production. Come and take a look and give your opinions by the way." Wang Hongxi said proudly.

This general drawing of the C100 curved beam frame was designed by Wang Hongxi personally and led more than 20 colleagues from the Technical Quality Department to design a masterpiece that took three months.

The design level is so high that even the technical minister Liang Hongjun, who is the technical minister, praises it.

In Wang Hongxi's opinion, although Zhao Guoyang is a serious college student, he has just graduated and it is probably very good to be able to understand such complex professional drawings.

As for giving suggestions, I'm just saying polite words.

Unlike Wang Hongxi, Liang Hongjun was quite looking forward to Zhao Guoyang's reaction.

This young man has a maturity, stability and technical aspects that his peers do not have. Liang Hongjun has the idea of ​​attracting such talents.

Among the four people present, Ma Jian may be the one who is the most confused.

As the highest level of negotiation personnel from Hongda Machinery Factory this time, he certainly hopes to bring more orders to the factory.

However, he himself is not proficient in technology, and he only knows a little about the frame diagrams in his factory.

The frame drawing that the other party took out now is far more complicated than the first batch of frame drawings made by his own factory, so Ma Jian was a little confused.

At this time, his only hope was to put it on Zhao Guoyang.

Zhao Guoyang was not surprised by being watched by three people in the office.

After he took the drawings, he looked carefully for a while and couldn't help but exclaim: "Minister Wang, your frame uses a single-tube cradle-like structure. This is a great innovation in our domestic motorcycle industry."

When Wang Hongxi heard the words "single-tube cradle-style structure", he felt dull on his face and his mouth was even more open, looking incredible.

Liang Hongjun next to him was not much better either. His eyes looked at Zhao Guoyang like he was looking at aliens.

Ma Jian was the only person on the scene who couldn't understand. At this time, he saw the two ministers of the Technical Quality Department of Siyang Group in a daze, and he couldn't help but whisper to Zhao Guoyang: "Guoyang, this... what is the 'single-tube cradle-type structure'?"

The leader asked, and of course Zhao Guoyang had to explain patiently: "Director Ma, this 'single-tube cradle-type structure' is one of the three main structural types of motorcycle frames."

"Generally speaking, the frame structure of a cradle frame composed of a single steel pipe is called a single pipe cradle frame. The other two structural types are fork-shaped pipe cradle frames and double-row pipe cradle frames."

"The difference between these three types of frames in use is mainly determined by the different structure of the engine. In addition to the size and shape of the engine, it is also related to the position of the engine in the frame. After all, which frame is chosen is mainly to arrange the exhaust pipe and intake pipe of the engine more reasonably."

"If a motorcycle uses a twin-cylinder and four-cylinder engine with the exhaust pipes separated on both sides, then in general, a fork-shaped tube or a single-tube frame will be used; if it is a three-cylinder engine and the exhaust pipe is placed in the middle and both sides, a double-tibe frame will be used; a single-cylinder engine will occasionally use a double-tibe frame or a fork-tibe frame."

As Zhao Guoyang said, pointing to the cradle-like structure on the general map, he said to Ma Jian: "Director Ma, you see, this cradle-type frame not only has ideal strength and rigidity, but also has beautiful shapes and a strong sense of strength, which is conducive to the structural layout of the car."

"But the production and manufacturing process technology requirements of this kind of frame are relatively high. At present, as far as I know, only island countries and some developed countries in Europe and the United States use this structure. The frame structure of Siyang Group should be the first among our domestic motorcycle models, and it is a great technological innovation."

Zhao Guoyang's explanation was so clear that it was no longer clear. Not only did Ma Jian nod his head after hearing this, Liang Hongjun and Wang Hongxi next to him stared at Zhao Guoyang without any moment, as if they were looking at a monster.

After Zhao Guoyang finished speaking, Ma Jian suddenly realized.

He did not notice the expressions on Liang Hongjun and Wang Hongxi's faces, but said flatteringly: "Minister Liang, Minister Wang, your factory is really amazing. It has set a precedent for our domestic motorcycle manufacturing industry. I really admire it!"

After Ma Jian finished speaking, Liang Hongjun and Wang Hongxi did not react much. Ma Jian, who felt a little embarrassed, noticed that the two leaders of the Siyang Group were staring at Zhao Guoyang with wide eyes.

Ma Jian's heart trembled and he was a little wrong, thinking that something had happened to Zhao Guoyang's explanation just now.

He quickly explained: "This...Minister Liang, Minister Wang, Guoyang is young. If you say something wrong, you two will forgive me..."
