After completing the study of the confidentiality regulations, it was just 12 noon. After lunch, Chen Nian came to the classroom as planned.
His class schedule has been readjusted and most of the unnecessary courses have been cancelled--of course, assessments have been cancelled.
In the eyes of other students, he just skipped a lot of classes.
Two sections of high numbers and two sections of large objects provided him with some relatively basic knowledge, and he got 0.01 source points. Compared with the number of source points required by the F119 engine, it was a drop in the bucket, but it was better than nothing.
Chen Nian is not too impatient, because he knows very well that what he lacks most now is the training of basic knowledge and basic theory. Once this part is done, he can learn other specialized subjects to brush up his source points later. It will be much simpler.
After class, he and Li Xiang went to the cafeteria to eat together, and happened to meet two brothers, Qiu Mai and Qiao He, so the four of them sat together.
After putting down the plate, Li Xiang couldn't wait to ask:
"Hey, Chen Nian, how's it going? Did it go well for you there? Did you get any unexpected gains?"
He was talking about Chen Nian's "business trip" to Fengtian 601 Institute. From his perspective, it was a somewhat special but reasonable visit for outstanding student representatives.
"Uh...it's okay. How can this go smoothly? Anyway, I was taken around to look around and then played in Fengtian for a long time."
"It's bad, not all public-funded tours are like this. It's nothing special."
Chen Nian's answer was flawless, and this was also the caliber that had been designed long ago.
"Didn't you see anything new?"
Li Xiang was slightly disappointed.
"When will it be my turn to see confidential things..."
Chen Nian sighed in agreement, but he was telling the truth. When he went to Fengtian, including the time he was in Fengtian, in fact, his confidentiality sequence had not been mentioned yet. Except for the No. 22 project, in fact, the 601 institute Not to mention seeing most of the area, he couldn't even get close.
"That's right...I thought I could get in touch with things that we usually can't get in touch with."
"It's not that simple. Last time, Mai and I went to the Beijing Institute of Mechanical and Electrical Engineering. Like Chen Nian, we just walked around casually. The next day, we were arranged to watch a flag-raising ceremony. It was basically like traveling. almost."
Qiao He on the side interjected.
"Are you also a student representative visiting?"
Qiu Mai nodded and replied:
"Yes, I went with my brother. It wasn't very interesting."
Seeing her bored expression, Chen Nian secretly sighed:
Although this matter is indeed not very interesting, for ordinary students of NPU, it is actually a great honor.
In other words, these two academic masters in front of me could not take it seriously.
But when Qiao He mentioned the Beijing Institute of Mechanical and Electrical Engineering, he suddenly remembered something:
Isn't there a superplastic forming machine at Beiyan Research Institute?
I don't know if they saw it.
Thinking of this, he asked smoothly:
"What did you see when you visited the Beijing Research Institute?"
In fact, he didn't expect to get any useful information from the two brothers and sisters. If he really wanted to analyze the superplastic forming machine in the future, the best way would be to consult experts in related fields through Chen Guo.
This is the most secure and provides the most accurate information.
But unexpectedly, Qiu Mai's answer was far beyond his expectation.
"Actually, it's nothing. I looked at everything, and I focused on the GLEEBLE1500 - it's the superplastic forming machine."
"Hey, those of you who build airplanes must have heard of superplastic forming, right?"
Chen Nian didn't respond, while Li Xiang nodded and followed Qiu Mai's words and asked:
"You know, many of the high-strength materials used in aircraft are superplastically formed, such as engine blades and the like."
"But I've never seen a machine before, and we haven't learned that much - how about the machine? Is it easy to use?"
Qiu Mai on the opposite side sighed and replied:
"It's so easy to use. It's a product that is two or three generations behind."
"I can only say that it is barely usable."
"Actually, the performance of GLEEBLE1500 is far behind the current international average level, but we have no choice but to use it."
“I was thinking about doing the reverse before, but later I found out that this was not something I could do at all.”
"Don't talk about me. Those senior brothers and sisters at Beiyan Institute have been busy for five years, but in fact they haven't made much progress."
"The copied products are too poor, mainly due to problems with the high-pressure and hydraulic modules, which results in the yield not improving..."
Hearing this, Chen Nian's eyes lit up.
Sure enough, just like what I learned in my previous life, the core performance constraints of the superplastic forming machine lie in these two modules.
If this is the case, then you are on the right track.
"What exactly is the problem?"
Chen Nian asked pretending to be curious.
"Superplastic forming equipment does not have a heating module and relies on energizing the material itself to heat it. In this process, the material is required to be rapidly heated to more than 10,000 degrees Celsius, and at the same time, the temperature must be accurately controlled through a computer system."
"Therefore, the performance of high-voltage modules is extremely important. Our main difficulty lies in high-power capacitors. We are too weak in this area."
Chen Nian nodded slightly. In fact, this problem has not been solved even ten years later. We still have to rely on imports for most ultra-high power capacitors.
----However, it may not be necessary now.
What if we put the target of analysis on the capacitor?
Chen Nian quietly brought up the system panel and modified the analysis target. This time, the number of source points required for analysis has indeed dropped significantly!
Only 0.1 source points are needed!
Doesn’t this save another 0.1?
Comfortable!
He closed the system interface with satisfaction, and then continued to ask:
"Apart from this? What is the main problem with the hydraulic module?"
"Accuracy, the hydraulic movement speed of a superplastic forming machine must be as low as 0.01 mm, but the speed of our ordinary hydraulic press is generally between a few millimeters to tens of millimeters. If it is any lower, it will cause crawling jitter."
"This is very important. If the speed is not slow enough, the formed metal will generate a lot of internal stress and may even deform and rebound."
"This is not a problem that we can solve in a short time..."
You can't solve it, I can!
Chen Nian thought to himself.
He couldn't wait to ask further:
"Then how can we slow down the speed?"
"The current directions are spherical articulated joint structures and parallel moving beam ultra-low speed hydraulic systems, but these two directions are very difficult. My graduate project is going to be about parallel moving beams. I hope I can achieve results by then... ....”
After hearing her answer, Chen Nian quickly checked the analysis results of these two technologies in the system.
The result made him extremely happy.
It only adds up to 0.06 source points.
Good guy.
After doing this calculation, this meal directly saved him 0.24 source points!
Rounding it all off, it’s as close as one F-22!
He thought secretly in his heart:
Senior Sister Qiao, you are really a lucky charm.
However, your graduate project will most likely be changed...
