"This kind of car is so domineering." The next day, a group of people came to the missile force and finally saw this Scud missile launcher. The first moment he saw it, he couldn't help but shout.
The big guys built Mercedes-Benz heavy trucks and infantry fighting vehicles, which was already amazing. However, compared with the other party's missile launcher, it was a terrible witch.
Look, someone's off-road tire is almost as high as his chest. The thick off-road pattern looks like a unique feeling. If this thing is pressed on the ground, it will definitely not be afraid of any road conditions.
ah.
The most spectacular thing is the front of the car. The cab on both sides is like a grasshopper, with a head stretched out, with big eyes on both sides, which looks particularly rough.
And in the middle of the two cabs is the engine.
At this time, the lid in the middle of the cab had been opened, and the V12 engine was displayed in front of everyone. The red cylinder head and the metal-light high-pressure oil pipe were all like a strongman showing his muscles
generally.
This is the example of the aesthetics of violence!
Everyone was filled with excitement when they saw it.
At this time, at the front of the car, several engineers from the pyramid country were frowning there.
They stood on the bumper in front of the front of the car, looking at the assembled engine inside, muttering something in their mouths.
No, still not!
Their missile launcher is really a mess. I originally thought it was just a matter of changing the engine. Although there are not the same model, many of them have similar models, and the positions of the anchor screws are the same.
After lifting it up, screwing the screws, it will work normally. Who would have thought that this kind of problem would actually occur?
shock!
For a military truck, vibration is not a big deal. It is impossible to pursue the stability of a sedan, but the vibration is too big. After starting the engine, the vibration will be quite large.
When I got up, the whole cab was like a boat.
If this continues, even if the driver can bear it, the missiles on his back cannot bear it. If the missile is broken, it will not be launched.
They were racking their brains here, not knowing how much they had already started to think about it.
"Everyone, our friends from the Eastern Power are here, let them see if there is any solution." Srief continued to lead the team, and now he shouted to the people above.
At this time, those people turned around and looked at the people wearing the same military uniforms, all of which were unexpectedly strange faces. The leader jumped down.
"Hello everyone, my name is Said, the power system engineer of ** Company." Said said: "After we replace our tank engines, there will always be unexpected problems."
The pyramid countries, unlike other countries, are also trying their best to develop their own military industry. In the past 20 years of development, they have also made good progress. They can produce rifles themselves, they can make cannons themselves, and they can also make their own.
Overhaul tanks, etc.
Even fighter jets can be produced by themselves, called Helevan HA-300. Of course, the appearance looks no different from the Phantom aircraft.
Originally, there should be no major problem with the engine installed and the model is similar. Who would have thought that such a collapsed situation would occur.
"Please allow us to help, hoping we can find the problem." Qin Zhenhua said: "Now, can we take a look?"
"Of course," Said said.
So Qin Zhenhua climbed onto the bumper on the front of the car. From here, he could see the thick cab. Seeing the steering wheel and various operating levers inside, Qin Zhenhua felt itchy.
For normal vehicles, the windshield is tilted backward, which can reduce wind resistance, but the Russian military vehicles go the opposite direction and tilt forward, similar to the porthole of a warship, so that it can be easier to see the bottom clearly.
pavement.
The three-spoke steering wheel inside has no beauty, but after holding it, you can definitely feel the force coming from inside.
Qin Zhenhua thought in his mind, and then began to look at the engine below.
Since the other party is an engineer of the power system, he should have very strong abilities. The problem of them being helpless should be a big problem, so we have to take a closer look.
Generally speaking, vehicle vibration is a very complicated problem, which may be an engine problem or a transmission system problem. This violent vibration may occur when a certain gear is worn.
If we look at the system, this is a vehicle's NVH problem and needs to be studied through a special laboratory. However, when Qin Zhenhua bent down and saw the engine below, he had already roughly in his mind.
Judgment.
Their experience is not enough, so they will make such simple and stupid mistakes. However, this is also good, and in this way, it will be just a chance for oneself.
"What method have you tried?" Qin Zhenhua asked pretending.
"We have carefully calibrated the engine and adjusted the transmission shaft. Now we can be sure that it is because of the engine replacement, but the specific reason has never been found." Said said.
They did everything they could do. Now, after hearing the other party's words, Qin Zhenhua nodded solemnly: "Yes, I've done it all, but it still won't work. I think it's probably caused by resonance."
Resonance?
"When the vibration frequency of the engine is close to the natural frequency of the vehicle body itself, it will cause resonance." Qin Zhenhua said: "Its characteristic is that when a certain accelerator speed range is within the most violent vibration, even
You can feel the whole body vibrating.”
"Yes, you're right," Said said. "But how is this possible? We're replacing similar engines."
"Yes, it's a similar engine, but not a completely different engine. This can only be said to be a coincidence. Unless you find the same engine as the original, even if you change to another engine of the same model, you will still
A similar situation occurred.”
What Qin Zhenhua said was consistent with the other party’s conclusions over the past period. Now, after hearing Qin Zhenhua’s judgment, the other party frowned: “So, if this is the case, will we not be able to repair these vehicles?
?Unless we can find the original engine?”
"That's not necessarily true. You can try another engine." Qin Zhenhua said.
