Great Power Ship

Chapter 196 Core Algorithm
The other executives of the Hong Kong Island Shipping Company were shocked by this scene. They all looked at their executive vice president in surprise, and their heads were even more confused. What is the mathematical lofting of the hull?
However, Gao Chong didn't care about the strange eyes of colleagues around him, stood up from his seat, hurriedly walked to the opposite explanation board, stared at the board carefully for a while while holding his glasses, and then asked Wen Dawei: "Is your algorithm the European Aotokon algorithm, or the American Viking system?"

Before he finished speaking, he shook his head again, and immediately said to himself: "It doesn't look like... it should be the Japanese Nasd algorithm?"

After finishing speaking, he looked at Wen Dawei, the previous superior gaze was gone, and all that remained was the longing for the things at hand.

Wen Dawei chuckled: "This is the latest algorithm developed by our Zhujiang factory in a year and a half. We internally call it the 'high-end' ship math lofting method!"

"The core algorithm you developed yourself?"

Hearing this, Gao Chong's squinted eyes opened wide again involuntarily, as if he had re-acquainted with Wen Dawei, he looked up and down several times, and then he asked with uncertainty: "It's really you who made it yourself. of?"

"Otherwise, our site, personnel and equipment are all in place, why do we have to wait for the first half of the year to start construction for your ferry? In fact, we are waiting for this 'high-end' ship mathematical stakeout method!"

Wen Dawei was really right.

Shipbuilding is not something that can be built by just starting a business, especially the Zhujiang factory undertakes the orders for ferries and bulk carriers on Hong Kong Island, let alone be careless, otherwise its reputation may be ruined. Then the achievements of Dajin's transformation of shipbuilding will also be destroyed.

Therefore, although Wen Dawei was very active in the transformation, he became more cautious when it was put into production. Even if it was technically close, he would rather delay it than take risks.

This is the case with ship staking.

This is a basic process involving the overall structure of the ship and the amount of materials used.

Just like a wooden wine barrel for wine, which needs to be pieced together one by one with wooden spokes, the essence of a ship is that it is made up of various plates piece by piece.

And what kind of plates are needed for different parts is very knowledgeable.

Rectangular, square, triangular, trapezoidal, and horseshoe-shaped plates are better in flat places. What about places with many complex surfaces such as the arc of the ship's bottom and the bulbous nose of the bow?
And what shape of panels should be used for splicing to save material, construction time and cost?
This involves lofting and splicing of various plates.

The usual way is to make a proportional model of the ship to be built, and then test various shapes of plates on this model, and then enlarge it to the usable scale of the ship through a certain scale, and then start cutting, cutting and starting construction.

This process seems simple, but in fact it is extremely complicated, because the key is not the problem of the scale model, but the experience of the related plate configuration.

After all, there will be a large error in the process of scaling up, which leads to either more or less plates in different parts.

Of course, this is not bad. If there is a large part of the complex surface missing in a certain key part, it is not a matter of repairing a piece, but a major event that may affect the overall structure of the ship.

Especially in fact, it is often such an inconspicuous position on a warship that is related to the survivability and sinkability of the entire ship.

This is like a wooden barrel. The carrying capacity does not depend on the highest board, but on the shortest board. The reason is the same.

Therefore, the process of ship lofting is not only important but also related to the overall situation.

Because of this, those who can stake out in the shipyard are all senior masters or experts who are almost mastered in this industry, because only they can accurately calculate the amount of each plate with years of solid practical experience, so that the ship The ship successfully started construction and finally galloped to the sea.

And such masters or senior experts are the treasures of various shipyards and research units, let alone poaching people, even if they are seconded and used for two days, the original unit is not happy.

Without such a technical core, even if all the personnel, site, and equipment of Zhujiang factory are in place, there is no way to start construction. After all, the ferry on Hong Kong Island is a new type of ship, and the design can be outsourced to the ship design institute, but the production requires Zhujiang factory. The ship was completed, but it was difficult for Zhujiang factory to accurately stake out and cut the material.

How to do?
Wen Dawei had no choice but to organize his staff to gnaw this difficult bone first.

If you can’t find a suitable lofting master or expert, you simply don’t look for it, and just use mathematical methods to calculate the size and size of the boards you need.

Anyway, no matter how complicated the surface of the board for lofting and blanking is, it is essentially a geometric function problem. As long as the algorithm is proper, it can completely replace the old master and simplify the lofting or even make it a fool.

Because of this, from the beginning of the preparations for the transformation of the Zhujiang factory, Wen Dawei started research in this area, led by none other than Wen Dawei's wife, Zhang Mingli, the chief of the technical department of the Zhujiang factory.

It's not that Wen Dawei gave his wife special care, but that Zhang Mingli was good at mathematics since she was a child, and she has a deep attainment in this area when she went to university.

Thinking of a picture of a young and beautiful girl solving complex differential equations with an abacus, there is an inexplicable sense of disobedience.

But Wen Dawei has long been familiar with this scene, because when he was an educated youth in Linxiang, the provincial capital, his mathematics was taught little by little by Zhang Mingli.

Although up to now, Wen Dawei's poor mathematics skills have long been returned to Linxiang, the provincial capital where he once struggled, but that indelible memory will never be forgotten by Wen Dawei in his life, so he entrusted this dual task to Linxiang. For Zhang Mingli, Wen Dawei can rest assured.

But finding someone who is reassuring does not necessarily mean smooth sailing. Zhang Mingli's mathematics attainments are very good. Compared with a scumbag like Wen Dawei, she is still far behind a pure professional.

That's all, the most important thing is the lack of experience, there is no way, the more practical samples are involved in this complicated ship lofting calculation, the more realistic the statistical data will be, and the calculated plate size will be more accurate.

But in this regard, the background of Zhujiang Factory is a big zero, that is, few people have seen giant ships over [-] tons, let alone experience, as for learning from domestic friends and businessmen, it goes without saying. Your Zhujiang factory is just a fledgling recruit in the domestic shipbuilding field. Those who have experienced stakeout masters are all the top factories in each region. They don’t take your Zhujiang factory seriously at all. How can you learn from it?

Is it to show off like listening to their leaders reporting all day long?

As for Wen Dawei, he is not very smart at this time. After all, he has pretended too much strange knowledge in his previous life. He can know everything, but he doesn't go deep. It's okay to grasp the general direction, and he can only stare blankly .

Just when Zhujiang Factory was at a loss around the stakeout of the hull, an unexpected person solved this big problem that almost directly killed the shipbuilding plan of Zhujiang Factory!
