Along the way, passers-by turned their heads to look.
Li Shuyu's classmates saw it and said in surprise: "Wow, isn't that our star Miss Li? She travels on such a shabby bicycle. It's so simple."
Another sneered: "Haha, you are so naive. This is a Rolls-Royce, and I am tired of riding in the Mercedes-Benz. I have never ridden in this one. I am just trying something new, and you actually take it seriously."
When Han Weijun saw that Dong Qingjun had brought Li Shuyu over, he pulled him aside: "Aren't you fooling around? Why did you bring Li Shuyu here?"
Dong Qingjun said: "I asked her to come and help us look at the tram problems."
Han Weijun asked Li Shuyu again: "Don't you need to go to class?"
Li Shuyu smiled: "No need."
In fact, she didn't want to go. She went directly to class without military training, and her relationship with her classmates was relatively distant.
His popularity also made many classmates jealous.
In this industry, people are always trying to push each other down.
So every time she went in, someone would roll their eyes at her and talk in a weird way, intentionally or unintentionally.
Anyway, there is no big difference whether you take those classes or not.
She always goes to the library to read various professional books that interest her.
The young people in the R&D team of the automobile factory were very excited: the boss's daughter is a beauty, and a big star came to see their R&D! !
This is simply a good thing that happens once in a thousand years.
Everyone was vying to go up and show it to Li Shuyu so that Li Shuyu would notice them.
Du Xinwei jumped on first and slowly walked around in a circle.
When passing the speed bump, the rear wheel was still on the speed bump, and the car jerked its butt as if it was frightened. It waited for a few meters before falling back again.
Li Shuyu originally told herself not to laugh, otherwise they would definitely be embarrassed, but now she still couldn't help laughing.
Everyone covered their eyes secretly, and Han Weijun was even more embarrassed: It was really embarrassing to be thrown in front of the juniors.
Only Dong Qingjun looked calm.
Du Xinwei was a little flustered when he saw Li Shuyu smiling. As soon as he stepped on the accelerator, the speed suddenly increased.
The second time I passed the speed bump, I was much faster than the previous time. I didn't react at all. After driving for more than ten meters, I lifted up like a person shrugging his shoulders, stretched out the four wheels, ran for a few steps in a strange way, and then stopped. Falling back suddenly.
Li Shuyu couldn't bear it anymore and squatted down to laugh.
Du Xinwei felt aggrieved, so he drove back and stopped in front of everyone.
Li Shuyu finally held back her laughter, stood up and wiped her tears and said, "It's good, it's good. It's just that the reflex arc is a little longer."
Dong Qingjun clapped his fingers: "We tested the sensitivity of the electronic components, the inflation speed of the airbag, the sensitivity of the valve, and the shock absorber. There are no problems."
Li Shuyu asked: "What are shock absorbers used for?"
Dong Qingjun said: "The main function is to calm the vehicle body as soon as possible when driving over bumpy roads and ensure that the wheels are always in contact with the ground. Shock absorption is divided into hard shock absorption and soft shock absorption."
Li Shuyu: "What is hard shock absorption and what is soft shock absorption?"
Dong Qingjun: "It is difficult to describe hard and soft shock absorption directly. If I have to say it, it is rapid shock absorption and slow shock absorption. Hard shock absorption improves driving safety and dynamic stability, but makes passengers feel more abrupt and uncomfortable. On the contrary, soft vibration damping makes the driving more comfortable, but it is not safe when driving. It is easy to float when turning, and the road has potholes or is unstable when passing speed bumps. Because it is in the research and development stage, in order to ensure safety, we are now using it Hard shock absorption.”
Li Shuyu nodded slowly as if he understood: "I don't quite understand, is it necessary to make such a black and white distinction? Why can't it be transformed into soft and hard? For example, hard shock absorbers are used when curves and road conditions are bad, and hard shock absorbers are used at other times. Use soft shock absorption.”
Dong Qingjun and Han Weijun exchanged surprised looks, and then the two people got together and started discussing.
"Soft and hard transformation, is it possible?"
"It's possible. Using variable damping shock absorbers, you can achieve changes in the softness and hardness of the suspension."
"Then give it a try. It's better than being weird like this."
Dong Qingjun was excited and immediately started to make improvements. When he turned around and saw Li Shuyu, he remembered that she was still here. He touched her head and said in a coaxing tone to Sun Dacheng: "Thank you. Be good, I'll ask someone to take you back."
Then he ran away with Han Weijun.
Li Shuyu stood there blankly.
Du Xinwei came over and said coyly: "Miss Li, our factory director asked me to take you back."
Li Shuyu came to her senses, blinked and said, "No need. I'll walk back slowly by myself."
Du Xinwei wanted to persist, but unfortunately he could not muster the courage again.
I heard that Li Shuyu has a lot of personality. If he annoys her later, he won't be able to eat and walk away.
Li Shuyu slowly walked out of the test track with his head lowered.
Xiao Hei ran from nowhere and followed her wagging his tail.
Since Hei Tiao left, it was Xiao Hei who followed Li Shuyu, as if he was protecting Li Shuyu on Hei Tiao's behalf.
Li Shuyu always calls it "Black Stripe" when there is no one around.
"You're here." Li Shuyu touched its head and walked along the original main road of the mining area to the office park.
The plane trees on both sides of the road were planted when the mine was built. Now it has grown to the size of two people hugging each other. In summer, the green shade is like a canopy. Now that all the leaves have fallen off, it has a different beauty.
When Li Wenjun rebuilt this road, he left them behind because he wanted to leave some traces of the old mining area for people to recall.
She walked for almost half an hour before arriving at Li Wenjun's office.
Li Wenjun was listening to the report. When he saw Li Shuyu coming, he quickly ended the meeting, sat down and asked Li Shuyu: "What's wrong?"
While talking, he took two pieces of dried meat from the table and threw them to Xiao Hei.
He knew that Li Shuyu would leave his side soon, so he cherished every moment spent with her.
Li Shuyu recounted his experience at the test track, laughing while talking.
Li Wenjun sighed: "My daughter's technical sensitivity is really incredible. She can see the problem at a glance."
Li Shuyu pursed her lips and smiled: "Dad, don't praise me with your eyes closed. I am really blind and blind. I know very little about cars, so what I said must only be a small aspect."
She wanted to inquire from Li Wenjun before reminding Dong Qingjun.
Li Wenjun nodded: "Although it is only one of the reasons, you are indeed great. Because air suspension is inherently a complex system, which requires a long and painful research and development process. A lot of debugging and improvement work needs to be carried out to make the various components work together accurately. Cooperation requires very high requirements for parts and system integration. My preliminary analysis is that first, the overall suspension they made is too heavy. This depends on the processing technology of materials and parts, which is not that easy. The second is that the algorithm is backward and the processing time is too high. There is no electronic control unit to achieve precise control of components, so the reflection arc is long. This needs to be improved by the IT department and electronics factory."
