The Rise of Heavy Industry 1980

Wang Chaoyang said: "This needs to be analyzed on a case-by-case basis. According to the way of thinking in engineering, you can first calculate according to the four parts, compare the calculated results with the real situation, if the results are not much different, then the four parts are acceptable, if the difference is very large, then consider dividing it into eight parts, or even sixteen parts......

" Fang Yu heard this, and had a feeling of sudden realization: "Oh, according to this statement, Sister Miao Miao's algorithm is correct, because Sister Miao Miao has calculated many times, and the result must be in line with the real situation!" I'm sorry Sister Miao Miao, it's that I don't understand, I shouldn't question your algorithm.

"It's okay.

Zhang Miaomiao looked thoughtful, stared at the blackboard for a while and said, "Wang Chaoyang, I suddenly had an idea...... What I mean is that the existing calculation models are all for standard shapes, and complex shapes are not applicable, and if you follow your method of infinite division, no matter how complex the mechanical calculation of the structure is, it can be completed by simple mathematical formulas...... It's just a bit more computational.

"That's right!"

Hearing Zhang Miaomiao's words, Wang Chaoyang's eyes lit up, because what Zhang Miaomiao said was actually the idea of finite elements, and it was also the fundamental idea of computer-aided computing in later generations.

Zhang Miaomiao has a high level of understanding, but Wang Chaoyang didn't expect it to be so high. Those who are known as mathematicians and the founders of computers in later generations are nothing more than that, right?"

"That's right. In fact, your thinking has already been summed up, and the calculation method is called finite element.

Wang Chaoyang explained: "Remember what I said about the theory of one to four intensities? Finite element is a more accurate calculation method than the four intensities theory.

Zhang Miaomiao was overjoyed: "Really, what the hell is going on with finite elements, tell me quickly!"

Fang Yu was also very curious, and looked at Wang Chaoyang with a look of admiration.

Facing two pairs of exaggerated eyes of intellectual curiosity, Wang Chaoyang coughed lightly and said: "I know a little bit about the finite element algorithm, and I can teach it to you, but not now, because the finite element algorithm is too complicated."

Zhang Miaomiao thought that Wang Chaoyang was deliberately selling Guanzi, and glared: "Then when will you teach?" Wang Chaoyang said: "

The day after tomorrow or the day after tomorrow, I'll prepare a little...... And Miao Miao Fangyu, now our focus is on the improvement of the gearbox, and other things have to be in the back, understand?"

Zhang Miaomiao then remembered that the most important thing now is to complete the plan and the drawings after the improvement of the chassis, in order to Xi learn the finite element to delay things, it would be too undeserved.

However, from this moment on, the word "finite element" has completely aroused Zhang Miaomiao's interest, although he promised to focus on the chassis drawings, but Zhang Miaomiao still did not forget to emphasize to Wang Chaoyang that he must teach him the finite element calculation method.

"Don't worry!" Wang Chaoyang couldn't help but feel embarrassed, it was the first time he met a girl who was so interested in finite yuan.

"I...... I also want to learn about finite elements, can I Brother Chaoyang?" asked Fang Yu.

"Of course!" Wang Chaoyang was embarrassed again, this child's little transparent talent is really strong, if he didn't speak, Wang Chaoyang would have forgotten that there was a third person in the office.

In such a tense working atmosphere, two days flew by.

More than eighty percent of the chassis improvement plan has been completed, and the main work in the follow-up is to make drawings. And when it comes to making pictures, Zhang Miaomiao and Fang Yu are both good hands.

With these two generals, Wang Chaoyang was idle and got a teapot and good tea from Ma Sanyuan. When Zhang Miaomiao and Fang Yu were struggling to draw the picture, this person sighed and drank tea and ......

"Where's the preparation for the finite element thing?" Seeing Wang Chaoyang's graceful appearance, Zhang Miaomiao pouted and asked.

"Oh...... Soon, soon!" Wang Chaoyang choked on the tea leaves, but he hadn't prepared yet.

"The drawings can be completed today, and tomorrow we will tell us about finite elements!" Zhang Miaomiao said, the shy girl in the past somehow, now there is a little more undoubted momentum in her tone.

"Good, good. Wang Chaoyang grinned.

After lunch, Wang Chaoyang directly found Ma Sanyuan, and he wanted to ask Chief Engineer Ma where he could find the finite yuan books.

Ma Sanyuan has only heard of finite elements, but he doesn't know about them, let alone where there are relevant books.

"I don't know, but someone might know...... Dongxue's teacher is very knowledgeable, you may want to ask him. Ma Sanyuan said.

Ma Dongxue is preparing for the college entrance examination, her teacher is called Lou Xinci, very knowledgeable, it is said that she once had the experience of studying abroad, and then experienced various events, and finally fell into the municipal high school as a teacher...... Wang

Chaoyang first went to the school to find Ma Dongxue, and was led by Ma Dongxue, Wang Chaoyang came to the teacher's office, and met Lou Xinci.

Lou Xinci is a man in his forties, wearing black-framed glasses, his hair is neatly combed, and his speech and demeanor are very polite, but for some reason, he always gives people a feeling of "rejecting people".

After Wang Chaoyang explained his intentions, Lou Xinci apologized: "I'm sorry, I don't know what you said about finite elements, so I can't help you."

Wang Chaoyang was stunned, because he could obviously feel that the other party was not telling the truth. If it was in the past, Wang Chaoyang would not have persevered, but there was no other good channel at the moment, so he had to say again: "Teacher Lou, do you know that you can find relevant teaching materials there? Please help think about it, this matter is very important to me!"

Lou Xinci asked: "This is strange, how important can teaching materials be to you?"

Wang Chaoyang said: " I have two friends who are both interested in finite elements, and I promised to tell them about them, but finite elements are so complicated that I only remember the framework, but I can't grasp how to teach others.

Hearing this, the calm Lou Xinci showed a trace of surprise on his face, and asked, "So, do you understand finite elements?"

Wang Chaoyang noticed the change in the other party's expression, and felt that there was a play, so he explained a few more words, "The so-called finite element, as the name suggests, is to divide the complex structure into finite elements, and the transfer relationship between the elements is used to simulate the mathematical model of mechanics or thermodynamics, and the key difficulty lies in the calculation method of the matrix equation and the processing of boundary conditions.

A glimmer of light flashed in Lou Xinci's eyes, and the corners of his mouth trembled obviously.

But after that, Lou Xinci returned to his usual calm. After thinking for a while, Lou Xinci said lightly: "Although I don't understand finite elements, I have a friend who understands, my friend may have relevant books there, you wait for me here, I'll come when I go."

After speaking, Lou Xinci left the office and left the campus on a bicycle.

Ma Dongxue stuck out her tongue at this time and said, "Teacher Lou is really a weird person!"

Wang Chaoyang said: "Why do you say that?"
