For a moment, a violent back push came, which surprised Liu Dajun. Could the 59 tank be so powerful?
In fact, as long as he looked back, he knew that this 59 tank target vehicle had already removed everything that should be removed, and the inside of the turret was almost empty. This naturally reduced the tank's self-weight, so the tank
The thrust-to-weight ratio is increased, especially after the program debugging, the tank is already starting with the maximum power, which is of course very powerful.
Liu Dajun listened to the roar of the engine behind and felt the different feelings in the past. Then, as the tank accelerated, the second impact came.
Puff!
With the help of compressed air, the clutch separates the power, and then the inside of the gearbox is banging a few times. Then, the clutch is combined again. When the moment of combining, the gear position has been raised from first gear to second gear. This shifting action,
The pause was too obvious, it was like the action of a newbie who drove for the first time. Even if you were outside, you could see the tank storming clearly.
"This is the automatic transmission." Qin Baozhen said: "Engine speed, gear position, vehicle speed, all must be matched in place. Therefore, the gear shift design of this AMT transmission is very important. If it is not qualified,
With technology, there will definitely be such a tide. For driverless tanks, this kind of jerk does not matter, but if it is used on heavy trucks, it will not work."
Qin Baozhen has received several projects, and the tank changes are the fastest, and the research on the automatic transmission of heavy trucks has just begun. The principle of shifting the gear is simple, just replace it inside the transmission.
Just change the gear mechanism and move the gear mechanism, but it is not easy to change gears smoothly. There is a great test of program training. This initial design is very immature and must go through a lot of
Only by experimenting and constantly adjusting can you make gear shifting easier.
At this time, Qin Baozhen said this, and Wang Erzhu, who was observing the side, said: "Of course we know that we are not in a hurry. Mercedes-Benz heavy trucks have been improved for many years. We also need to spend a lot of time to improve this gearbox.
Design, this is technical reserve, technical pre-research."
At this time, black smoke came out of the tank's engine and had already begun to change to third gears. Liu Dajun inside the tank felt a little uncomfortable. He was originally very strong. No matter how bumpy it was in the tank, he could withstand it, but
Today, for some reason, I felt something churning in my stomach.
Fourth gear, fifth gear!
After changing to the highest gear, the tank had already started to the edge of the shooting range. So, a sharp brake sound rang out. The track on one side was locked and the track on the other side turned, causing the tank to turn like a tail-shaking turn, inside the tank
Liu Dajun's body suddenly tilted to the side and pressed tightly against the part there. His head also hit him, feeling dizzy.
It's too fierce? Even the Russian driver wouldn't dare to make such a turn at such a fast speed. This procedure is not good.
Liu Dajun felt the impact of the steering with some dissatisfaction. At this time, Qin Baozhen's voice came from the headphones: "Brother Dajun, how do you feel?"
"It's okay." Of course, Liu Dajun could not admit defeat. After hearing Qin Baozhen say this, Liu Dajun immediately replied: "The turn just now is so cool."
"Okay, then let's continue." Qin Baozhen shouted.
When steering, the speed of the tank decreased. The PLC control system inside moved to the third gear according to the pre-designed program, but the speed was slightly faster. Therefore, after changing to the third gear, the engine was buzzing and buzzing.
As he ascended, Liu Dajun felt something in his ears screaming.
The accelerator was added to the maximum, and the tank began to speed up again, continuing to four gears and fifth gears. After running at the highest gear for a while, there was another sharp sound of brakes, and the tank turned again.
Everyone looked at the tanks pounding there. At this time, Qin Zhenhua said with some concern: "Can the army bear this kind of struggle? After all, the army is no longer a young man."
Thinking back to the time, when he was in his prime, he was not afraid of any trouble, but now he is not young anymore. After his forties, his physical fitness has declined significantly. Liu Dajun has been in the army for many years. Although his health is better than that of ordinary people,
I'm afraid I can't stand this kind of tossing.
With this idea, everyone looked at the tank and stopped steadily after the tank started. After the engine was turned off, the people around dared to approach. Otherwise, if the tank suddenly started, it would cause an accident.
Liu Dajun crawled out of it with a pale face. He tried hard to squeeze out a smile: "During the whole process, I did not move any operating system, all of which were automatically controlled, and there was no problem. It is completely possible to use it for our troops.
of."
After saying that, he stood up. At this time, his legs were weak and he could not stand still. He could only lean on the tank.
"Hey, Dajun, are you okay?" Qin Zhenhua asked.
"No problem, it's just a bit bumpy, I..." Before he finished speaking, Liu Dajun suddenly turned his head and spit out in one mouthful.
Liu Dajun still wanted to maintain his dignity, but who would have thought that he would vomit it like this. Now, it was so embarrassing.
"It seems that our program still needs to be optimized." Qin Baozhen said: "Although as an unmanned tank, there is no problem with speed-up and steering, but if someone wants to be on it, it won't work.
We need to consider more situations.”
If it is just unmanned driving, then the jerks and the violent steering of the gear shift do not matter. However, if there is someone above, this kind of bump will be too uncomfortable. Moreover, it may become another platform in the future. Consider
There are more situations, so now we must improve it.
Qin Baozhen still has very strict requirements for himself.
"It's enough. You can get two sets for us first and let our tank hands practice, wow..." Liu Dajun couldn't wait to express the joy of success, but who would have thought that he would vomit again.
Qin Zhenhua looked at Liu Dajun's embarrassment from the side, thinking that this was also an interesting experience.
"Director Qin, someone is looking for him." At this moment, he walked over and said to Qin Zhenhua.
