Experts from China and the base areas were scattered throughout the physical experiment area and conducted comprehensive tests on the various transmission parts, armor, and electronic equipment that were improved this time.

In the aging laboratory, there is also an assembled transmission mechanism, which is subjected to an aging test under high temperature and high pressure to test the maximum service life of the improved device components under harsh conditions. Since the future will mainly be fought in high-temperature areas, a more comprehensive test of the alpine plateau has not been carried out.

This set of transmission system, not only the use of new materials, new metallurgical technology, the original parts have been simply replaced, but also the internal transmission mechanism has been redesigned in a small way, corrected some unreasonable parts in the early stage of design, reduced the irregular disturbance of torque in the transmission process, and reduced the unnecessary shear force on the transmission parts.

At the same time, due to the strong finishing ability of the base, the surface accuracy of the parts is extremely high, and the coupling degree between the transmission parts is higher, so that the service life of the entire transmission mechanism is greatly improved.

From the theoretical point of view, its non-stop high-intensity operation life has reached 500 hours, which is much higher than the basic motorcycle overhaul interval of 200 hours. Without being destroyed, it can basically guarantee continuous operations during three consecutive months on the battlefield, which is equivalent to two or three major battles.

Of all the retrofits, motivational improvement is minimal.

This is because there is no corresponding technology and experience accumulation in the base area, and there is no suitable production line and tooling equipment, so it cannot be comprehensively transformed.

The only improvement made to the motivation was the addition of a digital fuel-saving valve.

Through the main control computer, the tank crew members can switch between fuel-saving mode and non-fuel-saving mode, so as to reduce the amount of fuel supplied to the motor and reduce the power output to save fuel without the need for high-thrust power drive.

According to calculations, the use of this digital fuel-saving device can effectively extend the maneuvering distance of the tank by 8 to 17 percent, which can be regarded as the best means of improvement in the case of major surgery without the right engine.

In the whole test process, the experts used all kinds of advanced experiments and testing instruments and equipment in the experimental area, and imperceptibly left a deep impression that the base area was very rich and the equipment was very advanced. _>_> itw'w'w·. `y=a`w`e`n-8`．=>

This is also intentionally done by Guan Fei.

He is still waiting for these experts to vigorously publicize them after they go back, and then bring in more powerful military scientific research workers to form a strong research team for the military industry in the base areas.

The final test results showed that all the improvements planned by the local area were realized, and the original design requirements were 10 to 20 percent!

This is not surprising at all.

Any design will reserve a certain amount of redundancy, and due to the strong finishing ability of the base, the processed parts have high precision, and all meet or exceed the processing requirements. This is not one or two parts, but all the parts have extremely high precision, one plus one is far greater than two, so that the overall performance of the system jumps up, not only successfully achieved the expected goal, but even a small increase.

The experts felt that this result was both reasonable and unexpected.

The first group of experts to come over have been in the base area for more than eight months, and from what they have actually seen and understood, they are very clear about how strong the base area's finishing strength is. They were not surprised at all that the test products handed in by various departments were made with the same processing quality as handicrafts.

And it makes sense.

However, they still expressed extreme surprise that the base areas, which had no experience in military production, had achieved such good results under the condition of such a large scale of transformation.

It's a military product.

If it had been able to make good weapons with its strong finishing capabilities, Japan would have become a global military power long ago, and it would not have been impossible to build even a tank or an airplane.

To put it mildly, what to pay attention to in tank design, where to start with the appearance design, how to match the layout of each subsystem, how to design the ......transmission mechanism, etc., these are the most basic parts, I don't know how to design a ghost tank!

However, judging from the previous situation, the base area just doesn't understand anything, and is completely a layman.

At the discussion meeting between the two sides, the questions raised by domestic experts were all at a loss, and they could not even judge which direction to discuss from here, so they could only lower their bodies and ask them for advice. As a result, in the blink of an eye, they came up with a sophisticated design that exceeded their expectations, which was really incomprehensible to them.

Compared with the madness of domestic experts, although the experts in the base area were equally surprised, they were much calmer than their domestic counterparts. 8>w-w`w=．-y`a·w=e=n-8=．· c`o-m

Without him, I have seen a lot!

Yes, we don't have a foundation, because we don't have talent in this area, and the tall ones are short, just to catch ducks on the shelves.

But what's that?

We can't, aren't we still with the commander?

With him, it's no wonder that there are any miracles in reality!

And they weren't wrong.

Guan Fei is indeed not from a military background, and he doesn't understand the norms and standards of weapon design in this era, but he has a library of game materials.

Exterior design, which still needs his brains?

A handful of ready-made materials in the stock library.

Transmission mechanism?

There are hundreds of transmission mechanisms for various tank models in the material library, and he is not afraid that there will be no imitation objects, but he is worried about how to choose the most correct.

He doesn't understand all kinds of design redundancy, but he can count it!

He has more and more comprehensive design formulas than the whole world in this era combined, and in terms of the depth of cognition of various physical phenomena and constants in the real universe, who should pat his chest and say that it is stronger than him, a future person hundreds of years later?

This is like a person of this era, who traveled to the Ming Dynasty, even if he didn't know anything about cold weapons, as long as he had a full set of physical and chemical textbooks for junior high school and college, he would definitely be able to make weapons and muskets from that era!

If Guan Fei is not afraid of trouble, according to the specifications, sizes, and physical characteristics of each model part in the material library, re-select the materials, and calculate them one by one, he can independently copy the same performance as the original, and even the replica.

It's not that hard.

The difficulty is that there are too many parts, which is too cumbersome and time-consuming to calculate.

If he had done the 59 improvement project alone, he would never have been able to do it in less than a year and a half. How is it possible to be like this, he comprehensively grasps the general, determines the major policy and assigns the task, each is responsible for a piece, according to his requirements to design, he reviews and makes the final correction, and then handed over to the factory for processing, only one or two months to produce results.

This is the most fundamental reason why he wants to make a situation in the United States and now set up a military industrial bureau.

One hero, two gangs, one fence and two piles.

Relying on him alone, he will not want to realize his dream until he dies of old age.

……

In the neat workshop, on the tooling table, several stout manipulators turned to the side, grabbed a full-size armor plate, and grabbed it without much effort.

The front end of the manipulator, which mimics the skeleton of human hands, is made of high-strength alloy.

The outer layer of the hands is also wrapped with a layer of one-centimeter-thick cushioning material to reduce the damage to the parts when grasping, and the outermost layer is also covered with a layer of soft wear-resistant skin to protect the internal cushioning material like the skin of a human hand.

Several manipulators are as flexible as human hands, and the heavy armor plates are like lightweight pieces of wood, which are grabbed from the conveyor rack, placed on the tooling table, accurately positioned by the laser positioning system, and then firmly grasped and stabilized, without going through other fixtures, so that the edges of the two pieces of armor are accurately aligned, and then placed firmly in place on the tooling table according to the corresponding angle.

Above, another robotic arm consisting of an alloy skeleton and pipelines slowly lowered and began to weld the armor plate joints.

"Is this submerged arc welding?" Despite wearing goggles, the experts who came to visit were still dumbfounded, pointing to the robotic arm that was being welded.

"That's right! We have modified the automatic submerged arc welding machine to this robotic arm to make it more flexible for welding, and some welding parts with complex shapes can also be welded with automatic submerged arc welding machine to improve welding efficiency and welding quality. In this way, the welding degree of the submerged arc welding machine has reached two meters per minute, which basically meets the needs. Guan Fei, who also wore goggles, introduced to them, "We have made some improvements to the existing submerged arc welding technology, and before welding, some special alloy powder is evenly sprinkled on the joints in advance, so that the strength after welding is twice that of ordinary submerged arc welding methods, and the expected goal has been achieved." ”

In the process of his explanation, the welding machine has completed the operation, and the two separate armor plates have been welded into a single unit.

"Can we go up and have a look?"

"No problem!" Guan Fei made a gesture, and the technician at the tooling table immediately stopped the robotic arm movement. In order to ensure safety, the power supply is also cut off.

"Even the power is cut off, so why don't you start again next time?" Several experts in automatic instrumentation were surprised.

Guan Fei waved his hand: "No problem." In our automatic control system, there is a pre-storage function. The running track will be recorded at any time during operation, so it doesn't matter if the power is turned off. When it starts next time, it will bring up the last action record of the last time, and then continue to work according to the program settings. ”

They were talking below, and a group of experts had gone up to the tooling table to take a closer look at the results of the welding. The weld that has just been welded does not see the red light melted by heating, and when you look closely, you can feel a very faint trace of heat, and even if you touch it directly with your fingers, you will not feel hot.

"The temperature is so low!" The experts were shocked.

Welding is to use the electrode with flux to heat the electrode with an arc to generate high heat instantly, and then melt the metal material at the weld and weld it together to achieve certain physical properties.

However, this high temperature usually destroys the crystalline properties of the welded parts of the metal parts, resulting in changes in physical properties such as deformation, thereby reducing their mechanical properties.

The wider the weld and the larger the heating range, the higher the degree of damage to the metal parts. Therefore, for some metal parts with high strength requirements, after the completion of the welding work, it is necessary to re-apply local heat treatment or chemical treatment to restore their mechanical properties and meet the design requirements.

Therefore, many equipment with high strength requirements, especially the welding of military, aerospace and other equipment, will be welded by low-temperature welding and cold welding, so as to destroy the metallographic structure of the welding part as little as possible and reduce the deformation.

China is also carrying out research on cold welding technology, but due to its poor technology, little experience accumulation, and closed-door construction, the effect is not very good.

Seeing this welding equipment, after welding, the heat was very small, even if you immediately touched it with your fingers, you didn't feel hot, everyone was surprised, but also excited. It was as if the unity had received the signal, and everyone jumped up with excitement, whether they were old or young, they all hugged each other warmly, screaming and jumping with joy.

That's great!

There is such a technology in the base area!

Needless to say, it is also clear that as long as there is a base area, it means that there is also a domestic area!

Judging from the actual welding effect just now, the weld is very thin, the width of the weld is less than one millimeter, and the welding slag is very small, and only a little grinding is needed after the welding is completed. In addition, from the perspective of the color change of the metal material around the welding, there is almost no change, that is to say, the welding does not cause damage to the metal parts, even if the heat treatment is no longer carried out after welding, it is not a problem to use it directly!

This kind of technology is even better than abroad!

They really came to the right place.

This is simply a treasure trove full of treasures, machinery, electronics, chemical industry, military ......, all kinds of advanced technologies that China has been thinking about for a long time, everything is available here, and it is within reach. When they were first appointed, they were afraid of disturbing their normal work, and they lost a lot of temper, until the good words of their superiors were exhausted and the interests of the country were brought out, and they reluctantly came over. But after they came, they felt that they had come to the right place.

If you don't come, how can you appear, in this deep mountain, there is such an unknown treasure!
