The military expert with a disdainful face said sarcastically: "Hehe, you, you're too naïve...... I don't understand the complexity of society. Haven't you heard of the lack of quality, the red envelopes are made up? Believe it or not, they will give each of us a big red envelope, let us open the net, let us sign for them. Plant 706 had never produced such parts before. ”

The expert was shocked and said, "It's impossible, isn't it? This is a matter of human life, and they have the courage to do it? Even if they have the courage, we don't dare to engage in favoritism." Military tribunals will not be kind to us. ”

The military expert next to him sneered: "You are too self-inflicted? As far as the strength of the Feixun Group is concerned, they will send us red envelopes? Our military gives them red envelopes, and people can make a lot of money with their 1800 horsepower turbocharged intercooled diesel engines, and they care about the torsion bar? Believe it or not, I conclude that the quality of the torsion bar they produce is definitely beyond our imagination. Besides, we are mainly looking at the material today, not at the torsion bar. ”

"No way! They're a machine factory, not the Flyun Group. The fact that Feixun Group is rich does not mean that they are rich in this machinery factory. The military expert with a disdainful face said in disbelief, "The torsion bar is by no means something that ordinary machinery companies can produce." The material is good, and the torsion bar quality is of course good. If the quality of the torsion bar is not good, it means that their material is not good either. Otherwise, they wouldn't have made the material directly into a torsion bar, so let's look at the test. ”

Maybe many people don't know that the shock and suspension system of a tank is different from the system of a car or truck.

The suspension system of most classic tanks adopts torsion bar suspension, rather than spring and leaf spring suspension as in ordinary cars. Torsion bar suspension is a tank suspension technology developed around World War II and has been used almost all over the world for a long time. Even the latest tanks are often torsion bar selection systems, or suspension systems that combine hydraulics and torsion bars.

The principle of torsion bar suspension is very simple, that is, the torsion bar is mounted on the side wall of the car body, and the weight load on the wheels of the tank twists the torsion bar through the swing arm, and the elastic force obtained is used to support the car body. The point of this suspension system is that it occupies very little space, the dynamic stroke is very large, the total length of the stroke can be close to twice the length of the swing arm, the elasticity and reliability are very good, the structure is not complicated, and it occupies little space in the car body......

This technique was massively used by tanks, including advanced third-generation tanks.

Although the structure of the torsion bar looks very simple, it has very high requirements for materials and strict mechanical properties.

The three technical experts from the military didn't know that although their discussion was small, it was clearly heard by Jiang Xinwei, who had a keen hearing. However, he did not break it, nor did he say anything to ridicule, because he believed that although these experts looked at people with colored glasses, they were all down-to-earth people.

They believe only the facts. As long as the facts are in front of them, they will be convinced.

When the workers completed the installation of the test pieces and Yu Zhize was about to direct the test, Jiang Xinwei opened his mouth and said to him: "Director Yu, since the military has come to experts, we will trouble them to test it, so that we can learn and learn." ”

Yu Zhize was stunned for a moment and asked, "Aren't we able to test it ourselves?"

Jiang Xinxu said with a smile: "I think they are more professional, and they have also tested a lot of torsion bars, so it is easier than us to find some problems that are difficult to find in tests." …… When we have learned, it is not too late to test ourselves in the future. ”

Seeing Jiang Xinwei's insistence, Yu Zhize didn't say anything more, just looked at the three military experts with his eyes.

The military expert who fully believed in the Shuangzhou Power Machinery Factory said in a low voice: "How about it, I said that people are not afraid, right? Now he has begun to command our army." ”

Jiang Xinwei said loudly: "Three experts, we are not very proficient in torsion bar testing, and we don't know much about the relationship between the data tested and their performance, can you please help us and let us learn and learn." You have helped us, improved the quality of tanks, and are also good for the troops. Is that okay?"

The look of disdain on the face of the expert who didn't believe in Shuangzhou Power Machinery Factory didn't completely disappear, and after listening to Jiang Xinwei's words, he asked coldly: "Do you really let us test? If the test fails, do you approve it?"

Jiang Xinwei smiled and said: "It is not up to you to decide whether the military products are qualified in the end? If you say that you are not qualified, you will definitely be unqualified, and we still have a way to make the unqualified products become qualified products." …… However, we Shuangzhou Power Machinery Factory has a requirement, that is, strict, strict and strict, the stricter you are, the more you can find the problems of our products, the more happy we are, the more we admire you, and the more we thank you. …… You should know how to test, right?"

Yes, in order to let them go into battle in person, Jiang Xinwei even used the radical method.

Having said that, the three military experts had no choice but to go into battle in person and direct the skilled workers to start testing one item after another.

Watching them test, Yu Zhize disagreed, feeling that their level was similar to his own.

As the test data came out, the three military experts showed surprise on their faces one by one, even the expert who originally believed in Shuangzhou Power Machinery Factory was a little unbelievable, not to mention the expert who doubted Shuangzhou Power Machinery Factory before:

"The resilience is so good? No way! Test again! You don't use enough pressure, right?"

"Is this so strong?

"The relationship between impact and stroke is so good, and it's too good to reduce performance, isn't it?"

"It's a material that's just a natural fit for torsion bars. ”

According to this data, this kind of torsion bar can carry a heavy tank of more than 80 tons. ”

"The coefficient of thermal expansion is very good, even if it is transported from the cold zone to the tropics at once, it has no effect on performance!"

"The comprehensive performance is good, and the one-way index is better!"

"This material can also be used as a tank track, and the performance is definitely good. We should try. ”

……

The torsion bar passed the performance test of the military experts very smoothly, and they were convinced one by one. In particular, they were even more stunned when they saw those few key figures: the performance was simply amazing.

The three military experts were convinced, and they all signed the excellent quality of the torsion bar in the conclusion column, suggesting that the military adopt it in its entirety, and at the same time solemnly signed their names.
