Five hundred and fiftieth chapters a long way to go
Now, the 80 tank has started to undergo repeated test runs. If nothing unexpected happens, this tank will likely be selected by the army and become a standard tank.
In this way, the engines equipped with them are also very important. The main breakthrough of this six-pair load-bearing wheel is the engine behind. Although there are several engines under research, it is truly mature and can be used.
That's just this one.
Zhang Baolin naturally cared about this engine.
"Have you found out the reason for the tube burst?" Zhang Baolin asked while walking: "I came here this time, mainly because of this problem."
Zhang Baolin was not here to ask for guilt, that was just a piggyback. This old technician was concerned about technical issues.
"Mr. Zhang, if you were here, nothing would have happened." Qin Zhenhua said this with emotion.
Generally speaking, technicians of Zhang Baolin have their own arrogance. When they encounter problems, they will never slap their butts, but will solve them together. There are only those who are dissatisfied with one bottle and swaying half a bottle.
Only then did they act like a lofty attitude. Jin Yonglin is such a person, so they suffered a loss.
I hope they can remember this lesson.
Qin Zhenhua thought in his heart and said, "It's basically solved. After inspection, we found that there was a problem with the engine bracket, which caused the diesel engine to vibrate too much. After a period of time, the supercharger's pipe was shaken.
It's open, and it doesn't match the pressure from the initial judgment."
Zhang Baolin nodded: "This is what I thought of on the road. We have undergone rigorous testing. The supercharger is too stressed and will relieve pressure. It is impossible for the tube to explode because of too much pressure. It is definitely another problem."
"Your experience is indeed rich. Mr. Zhang, is it good for you to stay in our first-machine factory? We are satisfied with what treatment you want." Qin Zhenhua said.
"You kid, you are indeed a personal talent, so I'm going to have a plan." Zhang Baolin said with a smile.
The atmosphere of the two quickly became harmonious. When they walked into the test yard, the 80 tank was undergoing a test drive. Watching it emitting black smoke, shuttle back and forth in the test yard, the eyes of the two were full of
Looking forward.
No matter how good it is abroad, it is still abroad. Only what you develop is your own.
The tank started a circle in the test yard and then returned to the starting point. When the tank stopped, Zhang Xiangqian came out of the tank, took off the tank cap, rubbed his ears, and said, "No, although it is better than before.
It's much better, but overall, I still feel that the vibration and noise are very loud. If I start like this for a long time, it will cause a considerable burden on the tank's body."
The vibration and noise are still quite good!
"We made this kind of discovery when we were on the bench. We look forward to the tank factory being able to minimize vibration and noise as much as possible when it was installed. Unexpectedly, we still didn't do it." Zhang Baolin said.
"This is brought out from the engine's womb, which is also related to our current scientific research situation. In the West, NVH research has become a key point, and we are still blank here." Qin Zhenhua said.
"NVH?" Zhang Baolin repeated Qin Zhenhua's words.
"Yes, it's the English abbreviation of noise, vibration and sound and vibration roughness. This is a comprehensive problem in measuring the quality of vehicle manufacturing. If we sit on our own 212, we will feel uncomfortable, but we will be in a car produced in Europe.
It will be very comfortable because of this NVH.”
Zhang Baolin nodded, yes, this thing should be taken seriously.
"Then what should we do?" Zhang Baolin asked.
"First is the control of its vibration source and noise source. We need to find out which components produce vibration and noise. For these components, we need to improve their vibration characteristics to avoid resonance; improve the balance of the rotating element, which requires
Scientific research and analysis, and for now, what we plan to use is to make a batch of precision-processed parts and replace them with this engine. We reduce the relative amount by improving the processing accuracy and assembly quality of parts.
The impact and friction of the moving element changes these situations.”
This is what everyone wants to do next, to improve the performance of the engine through precision machining, which only one machine factory can do.
This engine was built by the coal-provincial diesel engine factory. Now, the first machine factory said that it would improve it. If it were someone else, it would probably be annoyed. However, Zhang Baolin knew in his heart that this problem was when they were testing the bench.
I discovered it, but they couldn't solve it, so they could only rely on the Yima Factory.
Precision processing is the most important thing.
"Where is that German diesel engine?" Zhang Baolin asked.
The 1223 prototype car is equipped with its own engine and the 1224 prototype car is equipped with the engine imported from Germany. At the back, there will be 1225 and 1226 prototype car.
These prototype cars are all built at the first machine factory.
If it weren't for the people in the R&D room to delay, these prototype cars would have been built long ago! After hearing Zhang Baolin's question, Qin Zhenhua said: "You stay for a few more days, and the 1224 model car will be able to test the car. Now,
This prototype is still in the final assembly.”
Zhang Baolin nodded.
In the test yard, we waited until the tank test run ended and studied some minor problems together. In the afternoon, accompanied by Qin Zhenhua, Zhang Baolin met the 1224 experimental prototype car that was being finalized in the factory.
Since it is a prototype car, it is all different. Although it is all six pairs of load-bearing wheels, in order to install the larger 8V331 diesel engine and the supporting radiator, the rear of this tank and the engine compartment are
The space is larger, not only increasing the length backwards, but also increasing the height upwards.
The abrupt engine top cover on the top is in sharp contrast with other tanks. There are two round heat dissipation holes on the top cover, which looks even more weird. If you look down from above, it is like
It's like two big eyes.
Of course, if you want to see it at first sight, you will never be attracted by the engine compartment. The most attractive thing is its turret. Unlike the round cast turret before, it has become welded with edges and edges.
The horn turret, and the front of the turret is still in a certain arc, and the shape is quite beautiful!
Anyone will be attracted by its turret first, but Zhang Baolin's eyes quickly moved away and turned to the engine compartment behind.
