60s: I have a store

Chapter 415 A Group of Light Bulbs
After hearing this, the Zhangye group members' eyes lit up and they began a heated discussion.

Cheng Lefeng asked: "How can we be sure that the spindle is in the resonance range? And how can we calculate the appropriate natural frequency?"

Zhou Yimin thought for a moment and replied, "We can first do a simple vibration test using some existing instruments and equipment. Although the accuracy may not be high, it can roughly determine the abnormality of the vibration."

"As for calculating the natural frequency, I remember there is an approximate formula..." As he spoke, he wrote down a formula on a piece of paper. This was a formula he had seen in a popular science book before, and he didn't expect it to come in handy today.

It seems that having a good memory is a good thing. If your memory is poor, you won’t be able to remember this formula.

Everyone gathered around, looked at the formula, compared it with the data, and began to calculate and analyze. During the process, Zhou Yimin constantly inspired everyone to think about the problem from different angles, combining the actual production environment and machine operation conditions.

After some intense calculations and discussions, they finally decided on a new spindle design.

Theoretically, this solution can effectively avoid resonance and improve the stress conditions of the yarn.

But in actual situation, it still needs to be verified.

"Let's go to the lab and try making a simple model according to this plan!" Zhang Yan suggested excitedly.

Everyone immediately took action, carrying information and tools, and rushed to the laboratory. Zhou Yimin followed behind, his heart full of anticipation. If they could succeed, it would be considered a small contribution to the development of the motherland.

As soon as we entered the laboratory, everyone got busy according to the new plan.

Zhou Yimin had no choice. He was good at talking about it on paper, but when it came to practical operation, that was not his expertise. In order to avoid making a fool of himself and preserve the face of the so-called great god, he just watched Zhang Yan and the others take action.

After several hours of hard work, the simple model was finally completed. We carefully installed it on the test bench, turned on the power, and started the switch.

For a moment, the laboratory was so quiet that the only sound could be heard was the hum of the machines running.

Everyone stared at the model intently, their hearts in their throats.

The spindle was seen spinning at high speed, and the yarn was wound evenly without any signs of breakage or uneven winding.

The more times like this come, the more nervous everyone becomes, fearing that the yarn will suddenly break and we will be back to the days before liberation.

After more than ten or twenty minutes, the yarn did not break or show any uneven entanglement.

"Success! Success!" I don't know who shouted first, and then cheers broke out in the laboratory.

The team members hugged each other excitedly, tears of joy and pride in their eyes.

"Yimin, thank you so much! If it weren't for you, I don't know how long we would be trapped in this problem." Zhang Yan was so excited that she hugged Zhou Yimin directly.

When Cheng Lefeng and the others saw this, they began to tease, "I didn't expect Miss Zhang to be so proactive!"

When Zhang Yan heard this, her face turned red all of a sudden. She quickly loosened her arms around Zhou Yimin, then lowered her head, like a quail, without saying a word.

When Zhou Yimin saw his partner like this, he quickly stepped forward to help: "Thanks for all the hard work you've put in for so long."

The others did not continue. For this kind of thing, it is better to stop at the right time. If it goes too far, it will not only be a joke, but also a target.

Everyone gathered around and gave Zhou Yimin a thumbs up.

"Brother Zhou, you have so much knowledge. You grasped the key point right away and helped us solve the big problem!"

"Yeah, it feels like you know a lot of things we haven't come into contact with. Today is really an eye-opener."

Zhou Yimin smiled a little embarrassedly: "Don't be polite, this is the result of our joint efforts. I was just thinking about it and happened to come up with some ideas." Cheng Lefeng said straightforwardly: "Master, you are too modest. Without you, we would not have discovered the problem at all."

Zhou Yimin was a little embarrassed: "Comrade, can you please stop calling me a great god? I don't deserve it!"

Zhang Yan just remembered at this time, and then introduced: "Yimin, this is Cheng Lefeng"

Cheng Lefeng understood that he couldn't keep calling him that: "Then I'll call you Zhou Yimin, and you can just call me Cheng Lefeng."

Then I introduced the people around me so that we could get to know each other.

Zhou Yimin looked out the window and saw that it was getting late, so he suggested: "It's getting late now, why don't we go eat!"

This kind of thing is very common in later generations, and it is usually the leader who treats the guests.

When the people around heard this, they were a little hesitant. Not everyone is like Zhou Yimin, who has everything he needs.

Even for college students, the government provides subsidies, but they are only enough for one person to have enough food and drink. Moreover, many families still live in poverty and have to subsidize their families, especially in the current situation.

Zhou Yimin saw everyone's doubts and said, "Let me pay for this meal! You haven't come out to work yet!"

Anyway, he has no shortage of these things, and they can just help his partner deepen the relationship between classmates.

The others were a little hesitant because they were not familiar with Zhou Yimin and felt bad about spending so much money on him.

Although Zhang Yan felt a little heartbroken, she couldn't disagree since Zhou Yimin had already said it: "It's okay, let's just treat it as a get-together!"

After hearing that it was Zhang Yan who called, everyone agreed.

But there is a problem: with so many people, how to get there is a problem.

Cheng Lefeng said at this time: "How do we get there?"

This question stumped everyone at once. Zhou Yimin only had one motorcycle, and it couldn't seat so many people!

Zhou Yimin said at this time: "If not, I will go back and forth twice more and take everyone to the hotel."

Everyone's eyes immediately lit up. They had never even ridden a bicycle before, but they didn't expect that they would skip the bicycles and get on the motorcycle directly.

That was the happy decision.

The first group was that Zhang Yan held Zhou Yimin's waist tightly, and the rest of the people squeezed in. As many people as possible sat in the car, and if there was not enough space, they would go to the next one.

The afterglow of the setting sun shines on the paths of the campus, giving the entire campus a golden glow.

Zhou Yimin drove Zhang Yan and her classmates slowly out of the campus.

The roar of the motorcycle was particularly clear in the quiet evening. The breeze gently brushed everyone's faces. Zhang Yan put her arms around Zhou Yimin's waist and rested her head on his back.

Zhang Yan was thinking, if there weren't so many light bulbs, this would have been a great date. She could only look forward to the next time.

Zhou Yimin was thinking, it’s a good thing that overloading is not punished now. If you are caught in the future, your driver’s license will be revoked.
