This summer comes and goes fast.
In the blink of an eye, it was already late autumn.
Zhao Guoyang is sitting in his office at Hongda Machinery Factory, working on the first project of cooperation with Bombardier all-terrain sledding.
"Hongda Machinery Factory" and Bombardier have been cooperating 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 attention to this "partner".
Just a month ago, Samuel Carter, president of Bombardier ATV Manufacturing Company, had just come to Ninghai City for a trip and had more in-depth communication with Hongda Machinery Factory.
As a result of the communication, Bombardier ATV Manufacturing Company finally decided to cooperate with Hongda Machinery Factory on a non-ATV product.
All-terrain sledding, in fact, the full name should be "all-terrain snowmobile".
As early as 1959, the power empire Bombardier had already developed a legendary Skidoo snowmobile.
Bombardier's ATV manufacturing company has always been almost unrivaled in the field of snowmobiles, and there is a feeling of being overwhelmed by the heights.
But in the '90s, with the rise of brands such as Polaris and Yamaha, Bombardier faced a strong challenge in the snowmobile field.
Although in terms of technology, Bombardier is still firmly in the first position in the world.
However, because the price is too expensive, its products are much less competitive than other brands in the low-end market.
This time, Bombardier ATV Manufacturing Company decided to cooperate with Hongda Machinery Factory to produce a more advantageous product Hurricane snowmobile, which is to put it bluntly, to get a hand in the low-end market.
For this snowmobile project, Zhao Guoyang himself still has great expectations.
The reason is very simple, Huaxia itself has a wide area, and there is a demand for this kind of power machinery with strong off-road ability and high flexibility.
At present, Bombardier provides technology for free, and the products manufactured can directly form a monopoly in the domestic market.
After all, there are still too few local tyrants in Huaxia who can afford to import Bombardier SKIOO snowmobiles.
Of course, Bombardier is not a fool either.
What they provide to Hongda Machinery Factory is just the most basic general map.
If you want to refine the drawings of Hongda Machinery Factory itself, it will take a while.
What Zhao Guoyang is doing here is to point out the structural things in these general drawings first, so that the following technicians can look at these drawings more intuitively.
Since the "UGS company" has successfully implemented the X" software, this has saved Zhao Guoyang a lot of trouble when designing.
Not long after the comparison on the computer, the overall three-dimensional appearance of the snowmobile "Hurricane" was almost presented.
Zhao Guoyang compared the two-dimensional technical diagram given by Bombardier, combined it and carefully checked it, and there was basically no problem.
At that moment, he picked up the phone on the desk and dialed Zhang Chaoyang.
"Hey, Chaoyang, you and Feng Kaixuan are together, come to my office, I'm almost done with the drawings" Not long after putting down the phone, Zhang Chaoyang and Feng Kaixuan ran in.
Both of them are now middle-level cadres of Hongda Machinery Factory, and they are both deputy ministers of the second technical department, and they can be regarded as young and promising.
But in front of Zhao Guoyang, these two people are like elementary school students.
After entering the house, Zhang Chaoyang first sneered and said: "Director Zhao, you are too fast, you can get the three-dimensional general map so quickly."
Zhao Guoyang waved his hand disappreciatively and beckoned the two to come behind him.
"See, that's what the roughly three-dimensional shape looks like.
I've hid the important parts in it in layers.
If you want to see it, just select the hidden layer."
While speaking, Zhao Guoyang demonstrated it to the two.
In the past few months, Zhang Chaoyang and Feng Kaixuan, under the personal guidance of Zhao Guoyang, have improved by leaps and bounds in the level of three-dimensional cartography, and they can basically take charge of themselves.
At this time, under Zhao Guoyang's "ear to face life", the two quickly understood the meaning of this President Zhao.
"Well, I understand, the frame of Mr.
Zhao's snowmobile looks simpler than that of an all-terrain vehicle, and it shouldn't be difficult to manufacture," Zhang Chaoyang said with confidence.
Zhao Guoyang said "um", and then said: "That's not wrong.
This snowmobile is mainly composed of four parts: body, handlebar and skateboard, which is much less than the parts of an all-terrain vehicle. ” Speaking of this, Zhao Guoyang changed his words and said: "However, you can't underestimate the technical skills of snowmobiles because of this.
Its design is difficult, but it has to be above the all-terrain vehicle. ” "The 3D I'm drawing now is a top-down modeling.
Create the body first, then the handlebars, tracks, and finally the skateboard.
The commands used include Extrude, Swept, Pattern, Draft, Helical Scan, Sheet Metal, and so on. ” Listening to Zhao Guoyang's remarks, watching his hands fly as smoothly as flowing water, Zhang Chaoyang and Feng Kaixuan were both a little dumbfounded.
Although they are also proficient in using the "UGNX" three-dimensional software, in terms of operation, they cannot be compared with this Mr.

Zhao at all, and the difference is too far.
Zhao Guoyang may have also sensed their surprise, so he smiled and said: "You can't learn these designs for the time being, so don't worry."
Mainly, let's talk about some design difficulties after three-dimensional molding."
Pointing to the three-dimensional general drawing on the computer, Zhao Guoyang patiently explained: "Among them, one of the design difficulties that the two of you are most unsuitable for may be the reasonable way to deal with these many rounds." ” After Zhao Guoyang finished saying this paragraph, Feng Kaixuan was a little puzzled: "Mr.
Zhao, this is also available in the design of all-terrain vehicles, it seems that there is no difficulty."
Glimpsing Feng Kaixuan's rather confident appearance, Zhao Guoyang is a joy: "Triumph, the rounded corners of this snowmobile are not the same as 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 the snowmobile parts are not only different from those of all-terrain vehicles in terms of quantity; In terms of numerical values, it is also very exquisite, for example, these places, if you simply enter a radius of 3 rounded corners, then it will definitely not work. ” "The reason is simple, this is where the thighs are touched.
The rounded corners will still make the driver feel uncomfortable" Listening to Zhao Guoyang's eloquent talk, the look on Feng Kaixuan's face became solemn.
Originally, in his opinion, the relatively rudimentary design of rounded corners was not yet easy for him and Zhang Chaoyang.
But now listening to Mr.
Zhao's careful analysis, Feng Kaixuan knows that he is wrong, and he is very wrong.
After Zhao Guoyang explained, seeing that the two of them also understood about it, he stopped, pointed to the computer and said: "Okay, you two will also operate it yourself and try it to see what you can't understand about the three-dimensional overall design."
Zhang Chaoyang and Feng Kaixuan studied for half an hour before they roughly understood Zhao Guoyang's overall design.
With a long breath, Zhang Chaoyang wiped the beads of sweat on his forehead and said to Zhao Guoyang: "Director Zhao, you are right, this snowmobile looks simple, but it is really not so easy to design. ” "Just this shape, if I want to design it separately with Kaixuan, I'm afraid it will take a week or two."
After listening to Zhang Chaoyang's evaluation, Feng Kaixuan nodded again and again: "Yes, Mr.
Zhao."
If I were to have this three-dimensional general map alone, it would definitely take me a week or two to draw a look.
Moreover, accuracy is not guaranteed. ” When Zhao Guoyang heard this, he said happily: "This is normal, after all, your three-dimensional software is not used enough, and it will slowly get better in the future." ” Listening to the comforting words of Director Zhao, Zhang Chaoyang and Feng Kaixuan, you look at me, I look at you, they are a little helpless.
In fact, Zhang Chaoyang and Feng Kaixuan have been in contact with the "UGNX" software for more than three months, and they are definitely not novices.
But in the eyes of the two of them, if they want to achieve the operation of this President Zhao, I am afraid that they will not have a chance in their lives.
Zhao Guoyang didn't know what his two subordinates were thinking, and after comforting the two for a while, he pointed to the technical drawings provided by Bombardier on the table and spoke.
"Chaoyang, Triumph, I have roughly seen the drawings of these parts and components provided by Bombardier all-terrain vehicle manufacturing company.
Gearbox, I think we have the opportunity to make some improvements on the basis of it."
"Uh, the gearbox has improved," 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 meshing gears to achieve power transmission and variable speed shifting. ” "This transmission method, because of the large number of gears, is easy to cause the reliability of the gear transmission to be reduced, and it is easy to have a frustration in the process of shifting."
"The problem was that Bombardier used sand casting to complete the housing of the existing gearbox, and then installed multiple sets of gear structures in the housing."
"This kind of structure is too complicated to install, and the space requirements of the shell are large, and the difficulty of casting is also a problem.
On top of that, it's too expensive to produce and repair."
Speaking of this, Zhao Guoyang paused for a moment before he continued: "With so many unfavorable factors, such a design is not perfect. ” "If we can come up with a simple structure and a more stable gearbox internal gear structure, it will undoubtedly be a great improvement in technology":
