This summer comes and goes quickly.

In a blink of an eye, it was already late autumn.

Hongda Machinery Factory, Zhao Guoyang is sitting in his office and is studying the first project to cooperate with Bombardier - an all-terrain sled.

The cooperation between "Hongda Machinery Factory" and Bombardier has been with each other for some time.

With the hot sale of Hongda Machinery Factory's all-terrain vehicle series in North America, Bombardier has also begun to gradually pay attention to this "partner".

Just a month ago, Samuel Carter, president of Bombardier All-Terrain Vehicle Manufacturing Company, had a trip to Ninghai City and had more in-depth communication with Hongda Machinery Factory.

The result of the communication was that Bombardier ATV Manufacturing Company finally decided to cooperate with Hongda Machinery Factory to make a non-algammatic vehicle product.

The full name of an all-terrain sled car should be "any-terrain snowmobile".

As early as 1959, Bombardier, the power empire, had already developed a legendary car - the ski-doo snowmobile.

Bombardier ATV Manufacturing Company has always had almost no rivals in the field of snowmobile motorcycles, and it feels like it is too cold to be high.

But after entering the 1990s, with the rise of brands such as "Polaris" and "Yamaha", Bombardier encountered strong challenges in the snowmobile field.

Although technically, Bombardier still ranks first in the world.

However, because the price is too expensive, its products are much less competitive than other brands in the mid- and low-end market.

This time, Bombardier All-Terrain Vehicle Manufacturing Company decided to cooperate with Hongda Machinery Factory to produce a product with a better price and advantage - Hurricane Snowmobile. To put it bluntly, it is to make a move in the mid- and low-end markets.

Zhao Guoyang himself still has great expectations for this snow motorcycle project.

The reason is very simple. Huaxia itself has a wide area and has a demand for such power machinery with strong off-road capabilities and high flexibility.

Now, Bombardier provides free technology and products manufactured can directly form a monopoly in the domestic market.

After all, there are too few rich people in China who can afford to buy imported Bombardier ski-doo snowmobile bikes.

Of course, Bombardier is not a fool either.

What they provide to Hongda Machinery Factory are just the most basic general pictures.

It will take some time to refine the drawings of Hongda Machinery Factory.

What Zhao Guoyang has done now is to point out the structural things in these general drawings first so that the technicians below can look at these drawings more intuitively.

Because the "ugs company" has successfully assimilated the "ug-nx" software under the Windows system, this has saved Zhao Guoyang a lot of trouble when designing it.

Not long after playing on the computer, the overall three-dimensionality of the "hurricane" of the snowmobile was almost revealed.

Zhao Guoyang compared Bombardier to give a two-dimensional technical diagram, combined it and carefully checked it, and basically there was no problem.

He immediately picked up the phone on his desk and dialed it to Zhang Chaoyang.

"Hey, Chaoyang, are you with Feng Kaixuan together? Come to my office and I'm almost done with the drawings..."

Not long after putting down the phone, Zhang Chaoyang and Feng Kaixuan ran in happily.

Both of them are now middle-level cadres of Hongda Machinery Factory, and both are deputy directors of the Second Department of Technology, which can be considered young and capable.

But in front of Zhao Guoyang, these two people were as submissive as elementary school students.

After entering the house, Zhang Chaoyang first smiled and said, "Director Zhao, you are too fast, are you getting the three-dimensional general diagram so quickly?"

Zhao Guoyang waved his hand distractedly and greeted the two of them behind him.

"I saw it. This is the general three-dimensional shape. I have hidden the important parts inside by 'layering' method. If you want to see it, just select the hidden 'layer'!"

While talking, Zhao Guoyang demonstrated it for the two of them.

In the past few months, under Zhao Guoyang's personal guidance, Zhang Chaoyang and Feng Kaixuan have improved rapidly in the three-dimensional mapping level and are basically able to stand alone.

At this time, under Zhao Guoyang's "early and face-to-face", the two quickly understood what Mr. Zhao meant.

"Well, I understand, Mr. Zhao! The frame of this snowmobile bike looks simpler than an all-terrain car, and it should not be difficult to manufacture..." Zhang Chaoyang said confidently.

Zhao Guoyang said "Yes" and started to speak: "This is right. This snow motorcycle is mainly composed of four parts: body, handlebar and skateboard. It is much less than that of all-terrain vehicles."

Speaking of this, Zhao Guoyang changed the subject: "However, you can't underestimate the technology of snowmobile bikes because of this. The difficulty of its design is above all the all-terrain vehicles."

"The three-dimensional I'm drawing now uses a top-down modeling method. First create the body, then create the handlebar, track, and finally create the skateboard. The commands used include stretching, scanning, array, draft, spiral scanning, sheet metal, etc.."

Listening to Zhao Guoyang's story and watching his hands fly smoothly like flowing water, Zhang Chaoyang and Feng Kaixuan were both stunned.

Although they are all proficient in using the "ug-nx" three-dimensional software, they are not comparable to Mr. Zhao in terms of operation, and they are far behind them.

Zhao Guoyang may have felt their surprise, so he smiled and said, "You can't learn these designs yet, so don't worry. The main thing is to talk about some design difficulties after three-dimensional forming..."

Pointing to the three-dimensional general picture on the computer, Zhao Guoyang patiently explained: "One of the design difficulties that you two are most unacceptable to is probably the reasonable way to deal with these many rounded corners."

After Zhao Guoyang finished this paragraph, Feng Kaixuan was a little puzzled: "Round corners? Mr. Zhao, this is also available in all-terrain vehicle design? It seems that there is no difficulty..."

When Zhao Guoyang saw Feng Kaixuan's confident appearance, he was happy: "Qixuan, the rounded corners of this snowmobile are different from the rounded corners of an all-terrain car."

"Because of the small size and many areas that come into contact with the human body, the rounded corners on the parts of the snow motorcycle are not only different from those of the all-terrain vehicles in terms of quantity; it is also very particular in terms of numerical values... For example, if you simply enter a rounded corner with a radius of 3mm, it will definitely not work."

"The reason is very simple. This is where the person's thighs need to touch. Just a 3mm rounded corner will still make the driver feel uncomfortable..."

Listening to Zhao Guoyang's talk, Feng Kaixuan's expression became solemn.

In his opinion, he and Zhang Chaoyang were not good at making a more basic design like rounded corners.

But now after hearing Mr. Zhao's careful analysis, Feng Kaixuan knew that he was wrong, and it was ridiculously wrong.

After Zhao Guoyang explained, he saw that the two of them understood almost the same, so he stopped and pointed to the computer and said, "Okay, you two can also try it yourself and see what are the three-dimensional overall designs that you can't understand..."

Zhang Chaoyang and Feng Kaixuan studied for half an hour before they roughly understood the overall design of Zhao Guoyang.

After breathing a long sigh, Zhang Chaoyang wiped the sweat beads from his forehead and said to Zhao Guoyang: "Director Zhao, you are right. This snowmobile looks simple, but it is really not that easy to design."

"If I had to design this appearance alone, it would have been a week or two..."

After hearing Zhang Chaoyang's comments, Feng Kaixuan nodded repeatedly and said, "Yes, Mr. Zhao. If I leave this three-dimensional general picture alone, it will definitely take one or two weeks to draw a picture. Moreover, the accuracy cannot be guaranteed."

When Zhao Guoyang heard this, he happily said, "This is normal. After all, your three-dimensional software is not pure enough, and it will get better in the future."

Listening to the comforting words of Director Zhao, Zhang Chaoyang and Feng Kaixuan looked at me and I looked at you, and they were all helpless.

In fact, Zhang Chaoyang and Feng Kaixuan have been in contact with the "ug-nx" software for more than three months, so they are definitely not considered novice.

But in their own opinion, if you want to achieve this Mr. Zhao’s operation, you will probably never have a chance in your life.

Zhao Guoyang didn't know what his two subordinates were thinking. After comforting the two for a while, he pointed to the technical drawings provided by Bombardier on the table and spoke.

"I have roughly seen the parts drawings provided by Chaoyang, Triumph, and Bombardier ATV Manufacturing Company. I think we have the opportunity to make some improvements based on the transmission..."

"Uh, what's the improvement in the gearbox?" Zhang Chaoyang said in disbelief.

Looking at the confused Zhang Chaoyang and Feng Kaixuan, Zhao Guoyang explained patiently: "That's right, according to the drawings provided by Bombardier, the inside of their existing gearbox is mainly driven by gear meshing with each other to achieve power transmission and shifting gears."

"This transmission method, because of the large number of gears, can easily lead to a reduction in the reliability of gear transmission and may easily cause abrupt state during shifting."

"The problem with this is that Bombardier uses sand casting and then installs multiple sets of gear structures in the shell."

"This structure is too complicated to install, and the casing space requirements are large, so the difficulty of casting is also a problem. Most importantly, its production and maintenance costs are too high..."

Speaking of this, Zhao Guoyang paused for a moment before continuing to speak: "With so many adverse factors, this design is not perfect."
