The Rise of Heavy Industry 1980

Because the guest house has been arranged, Wang Chaoyang and Fang Yu can live in the Changhai Agricultural Machinery Compound. However, Zhang Miaomiao wanted to live at home, so after the night was over, Wang Chaoyang drove the girl home.

When I arrived at Zhang Miaomiao's house, it was close to half past eight in the evening. Zhang Lianjun smiled and didn't care, but Zhang's mother looked worried, her daughter came back so late, she was very worried about her safety, even if Wang Chaoyang sent her back, she was not at ease.

Zhang's mother's worry also lies in the fact that although Wang Chaoyang knows the roots, he has nothing to do with Zhang Miaomiao after all, and if he comes back together so late, he will be gossiped about by others after a long time.

And every time she thinks of this, Zhang's mother is a little dissatisfied, what does this Wang Chaoyang think, if she is interesting to her daughter, she will invite

a matchmaker to come over and say yes as soon as possible, what is it like to consume it like this! She mentioned this to Zhang Lianjun, but Zhang Lianjun looked indifferent every time, looking at that he was a hundred at ease with Wang Chaoyang, as for whether there was a matchmaker, he didn't care. This made Zhang's mother very speechless.

The next day, the work continued.

After eating at noon, Wang Chaoyang drove away from Changhai Agricultural Machinery and returned to Hongxing Factory. The ultimate goal is to complete a prototype by the 14th of next month, so he must go back in advance to discuss the production of the chassis with Wang Song.

After seeing his father, Wang Chaoyang introduced the situation, Wang Song wrung his brows and thought for a while, and then said loudly: "Although the time is very tight, I am confident that it can be completed......!

Wang Chaoyang was also silent. In the Northern War of that year, the enemy was the American imperialists, and the volunteers won the final victory with their tenacity and spirit of not being afraid of sacrifice, but they paid a heavy price. In that war, there was a huge disparity in military strength between the two sides, the US imperialist army was full of high-tech sophisticated equipment, while the volunteer army remained at the level of millet plus rifles.

Although Wang Song did not directly participate in that war, Wang Chaoyang's second brother died in the war, which is the reason why Wang Song choked.

"Chaoyang, this time we will work together to defeat Daurson!" Wang Song finally said loudly, his eyes widening red.

"Of course!" Wang Chaoyang also said.

The chassis is manufactured in Montenegro Metal, and Wang Song will personally keep an eye on Liao Zhiyong's progress, so Wang Chaoyang does not have to spend time on these things. And Wang Chaoyang himself knows that in terms of technical ability, he is better than his father, but when it comes to organizing production and coordination ability, his father throws himself several streets.

Leaving the Red Star Factory, Wang Chaoyang returned directly to Changhai Agricultural Machinery.

After entering the office, Wang Chaoyang found that the atmosphere was not right, Zhang Miaomiao, who was full of energy in the past, was sitting motionless at the table at the moment, poking her cheeks with both hands, and her brows were twisted together, as if she was competing with something.

Fang Yu stood aside, holding a few pieces of straw paper full of calculations in his hand, bowing his head and biting his lip, but he didn't say a word.

"What's the matter?" asked Wang Chaoyang.

"Brother Chaoyang...... I...... I made Sister Miao Miao angry......" Fang Yu whispered.

"What the hell is going on?" Wang Chaoyang was even more strange.

"That's right. Zhang Miaomiao's voice was slightly louder than usual, "I handed over the strength check of the bearing seat to Fang Yu to do, and I have already helped him choose the formula and parameters, as long as the formula is solved." But when Fang Yu was halfway through the calculation, I even said that the algorithm was wrong...... I explained it to him, but he still didn't understand it and insisted that the algorithm was wrong...... I have used this algorithm hundreds of times, how can it be wrong!"

"No, no, no, Sister Miao Miao, I'm not saying that the algorithm is wrong, I'm just ...... I just can't figure out why...... When calculating, I have to figure out the reason, this is what Brother Chaoyang instructed me......" Fang Yu's voice became smaller and smaller.

Wang Chaoyang took the calculation paper in Fang Yu's hand, looked at it and said

, "Fang Yu, why can't you figure it out?" Fang Yu glanced at Zhang Miaomiao cautiously, and then said: "The variable curvature fillet is different from the equal diameter fillet, but this formula still uses the verification method of equal diameter fillet, so I can't figure ......it out."

"Fang Yu, you have to take a closer look at the equation!" Zhang Miaomiao interjected, "Although the formula follows the verification method of equal diameter fillet corners, I have a transition, you calculate that the maximum radius of the fillet is 4 mm, and the minimum radius is 1 mm, I divide the algorithm into 4 mm, 3 mm, 2 mm and 1 mm four times, so as to obtain an approximate result, what's wrong?"

"......" Facing the fierce Zhang Miaomiao, Fang Yu didn't dare to speak. Although the ages of these two people are almost the same, in terms of momentum, Zhang Miaomiao is like a teaching director, and Fang Yu is like a high school junior who was arrested after peeking at a novel after the lights went out.

Wang Chaoyang couldn't help but laugh when he saw this scene, and asked, "Fang Yu, just say what you think, don't be afraid of her."

Zhang Miaomiao suddenly glared at her, and then her face turned red.

Fang Yu swallowed his saliva, and then said: "Sister Miao Miao divides the verification method of variable curvature fillet into four parts, but there is no way to correlate between each two points, it feels like dividing a rope into four sections, although each section has been calculated, but the four sections are separated from each other." This is just my feeling, not necessarily right, Sister Miao Miao, don't be angry.

Zhang Miaomiao said: "According to your idea, the curvature fillet cannot be calculated." I'm divided into 4, 3, 2, 1, and you don't think it's okay, and it's divided into 4, 3.5, 3, 2.5, 2, 1.5, 1, and you still think there's a problem. This curvature fillet is originally discrete, how can it be calculated if it is not counted like this?"

Fang Yu let out an "oh" sound and stopped talking. But it can be seen from his eyes that he still does not completely agree with Zhang Miaomiao's statement.

"Come with me and I'll give you an analysis.

Wang Chaoyang smiled and took the lead in walking to a clipboard next to the office wall, which Wang Chaoyang asked Ma Sanyuan to help make, in order to facilitate collective discussion of problems.

Wang Chaoyang picked up the chalk and drew a sketch of the rounded corners with variable curvature, the maximum curvature is 4 mm, the minimum is 1 mm, and then the curve is divided into four sections with three horizontal lines, and the four curves are marked with 4mm, 3mm, 2mm, and 1mm respectively.

This is the method used by Zhang Miaomiao, which divides the variable curvature curve into four parts, and the curvature value decreases in turn. Fang Yu thinks there is a problem with this method, but he can't tell what the problem is, right?" Wang Chaoyang asked.

"Uh-huh!" Fang Yu nodded hurriedly, in fact, the most fundamental problem was that he didn't know what the problem was.

Wang Chaoyang continued: "In fact, the problem Miao Miao has already said, that is, the accuracy is not enough, four parts are not enough, it can be divided into eight parts, and eight parts are not enough to be divided into sixteen parts...... But here comes the question again, how many portions are accurate enough?"

Fang Yu shook his head, indicating that he was not sure.

Zhang Miaomiao also frowned, not knowing the answer.
