King of Industry

Summer comes and goes quickly.

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

In Hongda Machinery Factory, Zhao Guoyang is sitting in his office, researching the first project of cooperation with Bombardier—all-terrain sled.

The cooperation between Hongda Machinery Factory and Bombardier has been going on for some time.

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

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

As a result of the communication, Bombardier All-Terrain Vehicle Manufacturing Company finally decided to cooperate with Hongda Machinery Factory on a non-all-terrain vehicle product.

All-terrain snowmobile, in fact, the full name should be all-terrain snowmobile.

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

For a long time, Bombardier All-Terrain Vehicle Manufacturing Company has almost no rivals in the field of snowmobiles, and there is a feeling of being overwhelmed.

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

Although technically, Bombardier still ranks first in the world.

But because the price is too expensive, its products are much less competitive than other brands in the 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-the Hurricane Snowmobile. To put it bluntly, it wanted to get a hand in the low-end market.

For this snowmobile project, Zhao Guoyang still has great expectations.

The reason is simple. Huaxia itself has a very vast territory, and there is a need for this kind of power machinery with strong off-road capabilities and high flexibility.

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

After all, there are too few local tyrants in China who can afford to import Bombardier Ski-doo snowmobiles.

Of course, Bombardier is no fool.

What they provided to Hongda Machinery Factory were just the most basic general drawings.

It will take a while to refine it into Hongda Machinery Factory's own drawings.

What Zhao Guoyang is doing 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.

Since the UGS company has successfully assimilated the UG-NX software under the Windows system, Zhao Guoyang saved a lot of work in the design.

Not long after making gestures on the computer, the overall three-dimensional shape of the snowmobile Hurricane was almost presented.

Zhao Guoyang compared the two-dimensional technical drawings given by Bombardier, and combined them to check carefully, basically there is no problem.

Immediately, he picked up the phone on his desk and called Zhang Chaoyang.

Hey, Chaoyang, are you and Feng Kaixuan together? Come to my office, I've almost finished the drawings...

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

Both of them are now middle-level cadres of Hongda Machinery Factory, and they are both deputy directors of the second technical department, so they can be regarded as young and promising.

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

After entering the room, Zhang Chaoyang first laughed and said: Director Zhao, you are too fast, you have finished the 3D general drawing so quickly?

Zhao Guoyang waved his hands indifferently, calling the two of them to come behind him.

See, the general three-dimensional shape is like this. I have hidden the important parts inside with the method of 'layering'. 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's level of three-dimensional drawing has improved by leaps and bounds, and they can basically be independent.

At this time, under Zhao Guoyang's instructions and orders, the two quickly understood what this President Zhao meant.

Well, I got it, Mr. Zhao! The frame of this snowmobile looks simpler than that of an all-terrain vehicle, so it shouldn't be too difficult to manufacture... Zhang Chaoyang said confidently.

Zhao Guoyang gave a hmm and said, That's true. This snowmobile is mainly composed of four parts: the body, the handlebar and the skateboard. Compared with the all-terrain vehicle, it has so many parts, which is considered less. Much more.

At this point, Zhao Guoyang changed the subject: However, you can't underestimate the technicality of snowmobiles because of this. Its design is more difficult than all-terrain vehicles.

The 3D I am drawing now uses a top-down modeling method. First create the car body, then create the handlebars, tracks, and finally create the skateboard. The commands used include stretching, scanning, and array , draft, helical sweep, sheet metal, and more.”

Listening to Zhao Guoyang's narration and seeing his smooth operation of his hands flying like flowing water, both Zhang Chaoyang and Feng Kaixuan were a little dumbfounded.

Although they can also use the UG-NX 3D software proficiently, in terms of operation, they can't compare with Mr. Zhao, and they are far behind.

Zhao Guoyang may have sensed their astonishment, so he smiled and said, You can't learn these designs yet, so don't worry. Mainly, let's talk about some design difficulties after 3D modeling...

Pointing to the three-dimensional general drawing on the computer, Zhao Guoyang patiently explained: Among them, one of the design difficulties that you two are most uncomfortable with may be the reasonable handling of the many rounded corners.

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

Seeing Feng Kaixuan's confident appearance, Zhao Guoyang was amused: Kaixuan, the rounded corners of this snowmobile are different from the rounded corners of all-terrain vehicles.

Because of its small size and many areas in contact with the human body, the rounded corners on snowmobile parts are not only different from those of all-terrain vehicles in terms of quantity; they are also very particular in terms of value... For example, in these places, If you simply input a fillet with a radius of 3mm, it will definitely not work.”

The reason is very simple. This is the position where the human thigh should touch. A rounded corner of only 3mm will still make the driver feel uncomfortable...

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

Originally, in his opinion, he and Zhang Chaoyang couldn't easily grasp such a relatively rudimentary design as rounded corners.

But now after listening to Mr. Zhao's detailed analysis, Feng Kaixuan knew that he was wrong, and it was very wrong.

After Zhao Guoyang explained, he saw that the two of them had almost understood, he stopped, pointed to the computer and said, Okay, you two should try to operate it yourself, and see what the overall three-dimensional design has. The place is still incomprehensible...

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

After taking a long breath, Zhang Chaoyang wiped the sweat from his forehead and said to Zhao Guoyang: Director Zhao, you are right, this snowmobile looks simple, but it is really not that good in design. Easy.

Just for this shape, if Kaixuan and I were to design it alone, it would take a week or two...

After hearing Zhang Chaoyang's evaluation, Feng Kaixuan nodded repeatedly and said, Yes, Mr. Zhao. If I were to leave this three-dimensional general drawing alone, it would definitely take a week or two to draw it. Moreover, the accuracy rate cannot be guaranteed. .”

When Zhao Guoyang heard this, he happily said, This is normal. After all, you haven't used the 3D software enough. It will get better in the future.

Listening to the comforting words of the director Zhao, Zhang Chaoyang and Feng Kaixuan looked at me and I looked at you, feeling a little 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 newbies.

But from their own point of view, if they want to achieve the operation of Mr. Zhao, they may never have a chance in their lifetime.

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

Chaoyang, Triumph, I have roughly read the drawings of these parts provided by Bombardier All-Terrain Vehicle Manufacturing Company. I think we have the opportunity to make some improvements on the basis of the gearbox...

Uh, an improvement in the gearbox? Zhang Chaoyang stuck out his tongue and said in disbelief.

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

This kind of transmission method, because of the large number of gears, can easily reduce the reliability of gear transmission, and it is prone to frustration during the shifting process.

The problem brought about by this is that Bombardier used sand casting for the existing gearbox casing, and then installed multiple sets of gear structures in the casing.

This kind of structure is too complicated to install, and the space requirement of the shell is relatively large, and the difficulty of casting is also a problem. Most importantly, its production and maintenance costs are too high...

Having said that, Zhao Guoyang paused for a moment, and then continued: With so many disadvantages, this design is not perfect.

If we can come up with a simple structure and a more stable internal gear structure of the gearbox, it will undoubtedly be a great improvement in technology!
