The Rise of Heavy Industry 1980

What puzzled Zhang Miaomiao was that during this experiment, there was no significant difference in the swing amplitude of the cables on the covers of the two cases. Zhang even noticed that as the load continued to increase, the swing amplitude of the two cables was almost equal by ......

This phenomenon was beyond the scope of Zhang Miaomiao's knowledge, she was not sure if Wang Chaoyang knew it, but she didn't find a chance to ask on this occasion.

The servo motor is still loading, according to the value displayed on the LED, the current load on the power system has reached 8.5Nm

! Don't look at this value is not big, but note that the unit is Newton meters! The value of 8.5Nm is applied to the 20 mm spindle, which can be described as terrifying!

The sound of the powertrain is getting deeper and deeper, and everyone knows that the time has come to really test the powertrain, and the advantages and disadvantages of the two gearboxes are about to be seen.

Suddenly, there was an abnormal noise, and the power system with the CC20-4 gearbox installed stopped.

Almost at the same time, another abnormal noise was heard, and the power system with the SP3 installed also stopped.

The huge experimental workshop entered silence in an instant. Everyone was silent, staring at the value on the LED display on the servo motor: 8.8Nm

"It's too much of a coincidence that both systems failed at

the same time?" "The ultimate load is 8,8Nm, and the performance of the two gearboxes is the same!" In other words, there is no winner in this running experiment?

" "How can this be, my God, so many of us have watched for more than two hours in vain?"

......

Voices began to emerge from the crowd, and it was clear that the reporters were complaining when they were talking. This result, while rare, is not what they were hoping for. After watching it for more than two hours in vain, in the end, there was no winner or loser, so what about tossing people to play?

Yan Hengshan also looked helpless, and discussed with Zong Shiguo in a low voice, but he couldn't get a result. The fact that the ultimate load of both gearboxes is the same is something that no one could have expected.

"Chaoyang, how could this be, it was a tie!" Hu Qingbin asked in a low voice.

"I didn't expect that...... But it doesn't seem to be a tie, let me think about it again......" Wang Chaoyang's words were a little vague, because there were some things he hadn't thought through clearly.

At that moment, there was laughter from the crowd of Doyerson. I saw Danio Griffin, who was tall in a suit and leather shoes, walked out of the crowd and said loudly: "It's not a draw, our Dolson's SP3 won!"

These words immediately aroused the dissatisfaction of Hu Qingbin and others.

"What do you say, the results of the experiment are obviously the same, why do you say that you won?"

"Don't get excited, dear Mr. Competitor, I naturally have my reasons!" Danio Griffin smiled slightly, looking very confident.

"In the last extreme test, the two gearboxes were tied, and the results were obvious to all, so I certainly won't say anything more. I'm talking about the last test, the double load test, in which our SP3 gearbox outperformed the CC20. Danio continued.

"Nonsense

!" the hot-tempered Ma Sanyuan replied loudly: "In the double load test, the performance of the two gearboxes is equal, which is also a fact for all to see!"

Danio smiled softly, shaking his fingers in the air and said, "That's not the case." There are details that you didn't notice, but I did, and I asked my translator, Ms. Don Anna, to record them. Now, Ms. Donanna, please help me explain it to everyone!"

"Glad to help, Mr. Danio.

Tang Anna was wearing a women's suit, dressed very carefully, and after nodding, she took out the black notebook in her shoulder bag and said: "Friends of Changhai Agricultural Machinery, friends of media reporters, in the course of the last experiment, Mr. Danio instructed me to record the vibration of the two gearboxes, and I recorded the vibration of the two cables on the top cover of the gearbox in the form of stick figures, please see here."

After showing the stick figures on the notebook, Tang Anna continued: "This recording method was also taught to me by Mr. Danio, in fact, I don't understand the principle, but Mr. Danio explained to me that the vibration effect of the SP3 gearbox is stronger than that of the CC20, because the amplitude of the cable CC20 is larger. There are also a lot of experts in Changhai Agricultural Machinery, I don't know if my understanding is correct?"

"Of course not! What does the cable have to do with the vibration of the gearbox? And the matter has passed, who knows if what you draw is accurate!" Ma Sanyuan couldn't help but shout, the situation has developed so far, the chief engineer is really anxious, otherwise he would not be angry with a girl who is not a few years older than his granddaughter.

"If the gearbox vibrates, it will vibrate with the cable, how can you say that it doesn't matter? Chief Engineer Ma, don't bully me for not knowing technology!" On the other hand, Tang Anna's mentality is very stable.

"......" Ma Sanyuan gritted his teeth and insisted, "Even if what you say is right, the matter has passed, and no one knows whether the things you drew in the notebook are accurate!" "

You don't believe what I draw, this is very easy to do, change to two new gearboxes, run the double load running experiment again, everyone pay attention to the vibration of the gearbox, you will find that what I said is true." Tang Anna said.

Ma Sanyuan was speechless. And I feel a little weak in my heart, seeing that the other party is so determined, nine times out of ten what he said is the truth.

Hu Qingbin was also silent, his fists clenched tightly. He was not reconciled, the competition progressed to this point, the limit load was not inferior to the opponent, only lost on twice the load of vibration, which is too embarrassing.

Zhang Miaomiao's heart is very conflicted, she knows in her heart that what Danio and Don Anna said is true, out of personal feelings, she doesn't want to say anything, at least she doesn't want to play the person who announced the failure of CC20 herself.

But from an engineer's point of view, she has to be realistic, even if she loses, she has to admit the facts, which is a more dignified thing.

"Wang Chaoyang, I want to tell the truth. Zhang Miaomiao turned her head to look at the man beside her. Wang Chaoyang

nodded and said, "You say ...... first" Zhang Miaomiao nodded, and then raised her voice and said: "Director Hu, Chief Engineer Ma, Mr. Danio and Ms. Tang Anna opposite, I will also tell you what I observed in the double load test...... The CC20-4 gearbox vibrates more than the Dowerson SP3 gearbox, so what Ms. Don Anna said is true.

As soon as these words came out, they caused an uproar.

Because Zhang Miaomiao belongs to the technicians of Changhai agricultural machinery, her public speech is tantamount to admitting the failure of CC20.

Hu Qingbin and Ma Sanyuan looked at Zhang Miaomiao in shock. In addition to the shock, it revealed more helplessness and regret. Just a little bit, just a little bit close to their CC20-4 beating their opponents.

It's a shame!
