Chapter 81 Maglev
In the middle of the office, on the large workbench, is a section of guide rail and a set of simple knife feeding system deployed around it.The system is surrounded by various fixtures and sensor probes.Oscilloscopes, multimeters and other measuring instruments are everywhere on the workbench.

"Senior Sister Zhao, what project are you working on?"

Chen Quan casually picked up a turning tool on the table.

"I am"

Zhao Weiwei glanced at Song Guoming standing at the door in surprise, who also had a similar expression on his face.

Chen Quan didn't behave like a freshman at all, but was very close to the mentor who often checked her progress, in demeanor and tone.

"What I do is."

After all, Chen Quan's international gold medal reputation is still there. Zhao Weiwei didn't think that Chen Quan was rude, but introduced the project seriously.

Since the emergence of computer technology, computer calculation and compensation technology have been a hot spot in the field of machinery and measurement.

For her doctoral dissertation, Zhao Weiwei naturally wanted to keep up with fashion and trends, so she came up with a similar topic.

The core of Zhao Weiwei's topic is to design an empirical formula after actually measuring the deformation data of the guide rail and the workpiece during processing, and then according to this formula, compensate and control the motion trajectory of the workpiece and the probe. When the system remains unchanged, the machining accuracy is improved.

In fact, this kind of subject has already been done.But this kind of project has too many variable parameters.

For example, the original weight of the workpiece, the cut weight, temperature, vibration, the cross-sectional shape of the guide rail, and even the material of the guide rail will affect the correctness of the empirical formula.

Zhao Weiwei, like everyone else, is constantly doing trial and error in this field to see who can find the most correct formula by hitting a dead mouse.

The whole process of trial and error is long and painful.She needs to continuously accumulate empirical data, then continuously improve the formula, and then continue to measure, endless iterations.

"Senior Sister Zhao, why don't you try, real-time detection and real-time control?"

After listening to the introduction, Chen Quan vaguely felt that something was wrong.

Half of this feeling comes from foreign memories, and half comes from the maglev train research base that I just visited in Germany not long ago.

The speed of the maglev train exceeds 600 kilometers per hour, and its precision requirements for guide rails and locomotives far exceed the ordinary machining level.A large number of new technologies and new processes have been adopted.

"Oh? What do you say?"

Zhao Weiwei became interested.

While talking, there was a burst of noisy voices in the corridor outside the door.

"Xiao Song, close the door!"
-
In the corridor, a group of freshmen from the 89 test came in.

Hearing the sound, Ma Rui walked out of the computer room.

"Mr. Niu Pin is not here. These books belong to the entire testing department. He asked you to share these books and take away the ones you use for 89 testing."

Niu Pin is the instructor of the 89 test.

"Let's work"

Squad leader Yang Sishan gave orders.

"You know that I just passed out, and you drag me to work."

Cheng Xing was a little unhappy.

"You passed out? What about me?" Yang Sishan rolled up his sleeves, revealing a piece of gauze around his elbow.

"what happened to you?"

Marie walked over. "Did you two fight?"

"There was no fight, but the injury was indeed because of him!"

"what happened?"

"At that time, I was drawing blood. I was drawing well, but he suddenly passed out behind me. The nurse who took my blood was shocked, so I became like this!"

As Yang Sishan said, he was very angry. "In the end, he's fine, and I'm fine! Shouldn't he do my job?"

"Haha, that's what it should be."

Ma Rui laughed enough and left.Leave a bunch of undergrads behind and sort the books yourself.

"What are you looking at? It's just such a job for two and a half people, and you're still lazy!"

Yang Sishan was angry again.

"I don't know, there seems to be something there."

Cheng Xing always felt that in the depths of the corridor, in a closed office, something attracted him.

in the room,
Chen Quan is describing what he saw at the maglev train research base in Germany.For some reason, he turned his head and looked at the closed door of the room.

in the hallway.

"Don't rush him all the time, he's not in good health."

Sun Jun made a relief from the sidelines. "Let's do more, isn't it over?"

"No, I'm not in poor health."

Chengxing didn't know how to explain his feelings and state. "I always feel that something should have happened, but it didn't happen, and my heart is empty."

"What should happen?" Sun Jun was curious.

"Yes. I have fainted before, but I have never passed out. I know that I fainted, and when I couldn't bear it, I would take the initiative to avoid it. But this time, the fainting came so suddenly that I didn't react at all."

"Forget it, don't think about it. The past is the past."

Sun Jun and the others didn't take it seriously.

Sorting books was not much at first, and it was done in a few minutes.Everyone bundled up the books they picked out, and each person took some, and then took them all away.

"Give me points. I still have one hand to use."

Yang Sishan took the initiative to walk over, taking part of Cheng Xing's hand.

A group of freshmen left the testing professional office soon.

The hallway was quiet again.
