originally thought that the previous questions were enough to make Qin Zhenhua completely defeated, and it didn't take a few questions to make him retreat, but in the last question, he caught up with the big competition and was about to start, so it was the most sloppy.

Although it is the most sloppy, Qin Zhenhua will definitely not be able to answer, because there is no machine factory at all, the first machine factory is the production of main battle tanks, 59 tanks, 69 tanks, are the main products here, as for the 63 armored car, it is not in the first machine factory, nor in the second machine factory, it was made in an unknown overhaul factory near the capital, and it was designed by a group of students in their early twenties.

They researched and tinkered, and finally came up with this field taxi, which was used to transport infantry soldiers while accompanying the tank, and as for the suspension system of this armored car, who knows?

Qin Zhenhua, who was born in a tank maintenance workshop, absolutely didn't know, because there were no 63 armored vehicles driving here at all.

Therefore, don't look at the simplicity of this question, Qin Zhenhua may not be able to answer it.

The last question, do you want Qin Zhenhua to get 100 points? Du Youwen's heart was all up and down, and at this moment, Qin Zhenhua spoke: "I'm sorry for you to read the question again." ”

If Du Youwen hadn't fallen asleep at the beginning, he should have been vigilant, Qin Zhenhua asked this question, it was purposeful.

However, even if Du Youwen knew that Qin Zhenhua had another purpose, he didn't have any choice, he had to read this question in its entirety, because he had just read it once, so he was more proficient this time.

"Please describe the working principle of the Type 63 armored car, the hydraulic suspension system." Du Youwen said.

When he finished speaking, the faces of several factory leaders present changed, Qin Zhenhua had a smile on his face, the last question, is it the climax of this competition?

"That's a wrong question." Qin Zhenhua said: "For now, the hydraulic suspension system is not mature at all, even abroad, only the United States and Germany jointly developed the MBT70 tank plan to use, however, this plan has gone bankrupt, as for our 63 armored car, with a torsion bar and hydraulic shock absorber suspension system, if this hydraulic shock absorber is called a hydraulic suspension system, it is completely Zhang Guan Li Dai." ”

After speaking, Qin Zhenhua waved his hand helplessly: "However, this can't be blamed on you, after all, you haven't seen it yet, and your knowledge is not rich enough, so it's too difficult for you to figure out the difference." Just by looking for information, copying some and taking it out for the test, and without really understanding it, it is not good at all. ”

Boom, there was a burst of ridicule below, and everyone was the same enemy after these questions.

Your R&D room is too good at bullying people, right?

This second level is completely okay if it is to be formalized, but who will, if a question like this is used to test everyone? Except for Qin Zhenhua, a freak?

Qin Zhenhua is venting his anger to everyone, he is demolishing the stage for the examiners, if they are like this in the future, who can stand it?

In the skills competition of the factory, if a person is the first, then he can not participate in it again, otherwise, let him be the first every year, then it will be repaid! Of course, the factory cannot participate, but can continue to participate, such as the national technician competition and so on.

In the future, everyone will take such an exam again, who will? Therefore, now Qin Zhenhua is also angry with everyone, laughing at Du Youwen like this, everyone feels very enjoyable.

"Qin Zhenhua, what are you talking about?" Du Youwen's face was flushed, the people in the R&D room usually walked sideways in the factory, how could they be laughed at by Qin Zhenhua like this in front of the public today.

"Our R&D room, we can do anything, this knowledge, what is it." Du Youwen continued.

"Okay, then you put down the information, don't look at the reference answer, tell everyone, in addition to reading the answer, will you also answer it yourself?" Qin Zhenhua asked.

As soon as Qin Zhenhua asked like this, Du Youwen wanted to put it down, but if he put it down, he really wouldn't answer! In an instant, embarrassment and annoyance rushed together, and their faces turned from red to purple.

With his expression, where can he hide it from others, in an instant, the workers below all understood, this Du Youwen will definitely not be able to answer! Put down this exam question, he can't answer anything!

Immediately, everyone started to talk about it, and cool words were everywhere.

"Turns out they won't."

"It's also used to test us, where do they get their sense of superiority."

"The R&D room, usually very bullish, it turns out to be such a bullish method!"

"That's it, look at Qin Zhenhua, that's called real ability, I really don't know, everyone can memorize books so well."

"Forget it, even at the level of a half-person like you, it doesn't represent the R&D room." Qin Zhenhua said: "Now, this is my last question, although the question is wrong, let me answer it." ”

After speaking, Qin Zhenhua glanced at the stage and saw Song Weize casting a grateful gaze, in fact, Du Youwen is already a relatively good technology in the R&D room, but when Qin Zhenhua said this, it can be regarded as saving some face for the R&D room, of course, Du Youwen will become the laughing stock of the factory in the future.

However, coming up with such a difficult exam question to test the master worker is originally impure in purpose, and it is completely different from what he explained, so it is also appropriate to let him suffer some hardships.

At the same time, today's big competition also shows Qin Zhenhua's excellent theoretical foundation, in the future, let Qin Zhenhua be the technical leader of the R&D room, who can object? In this way, we can quickly get the key surveying and mapping imitation out.

Qin Zhenhua cleared his throat and began to introduce: "We know that the basic structure of the torsion bar spring suspension system is that the load wheel is set on the balance elbow, that is, a crank turn, and the balance elbow is set on the torque shaft, which is made of special alloy and has great elasticity, so that when the load wheel is bumpy, the torque shaft will absorb a large amount of vibration energy of the load wheel through twisting, so that the chariot can run smoothly. However, although the torsion shaft can effectively absorb the violent vibration when the load wheel rises, the elasticity is greater when rotating, so that the load wheel drops more violently, on our tank, the weight is larger, and it is acceptable, but, the 63 armored car is not good, in order to solve this problem, the 63 armored car is equipped with a vane type hydraulic shock absorber at the 1st and 4th load wheels of the walking system, so that the vibration reduction of the suspension system is more gentle. In this way, the vibration reduction effect is better, the technology is mature and reliable, and the cost is lower. ”

After speaking, Qin Zhenhua looked up at Du Youwen above, and continued to ask: "How is it, is there a difference between my answer and your standard answer?" Do you want to read the standard answer again? ”

Where does Du Youwen have that face, he has the urge to get under the table, and Qin Zhenhua has already walked down in the admiring eyes of everyone.
