"Mr Qin, are you talking about high-speed trains like the island country's Shinkansen?" Someone asked a question below. Everyone is engaged in railways. Speaking of this, of course you all know.

Qin nodded his head: "Yes, that's understandable."

As far as high-speed trains are concerned, the island country is definitely a pioneer. As early as the 1960s, the island country opened this high-speed train in order to connect three famous metropolitan areas. The maximum speed exceeds 300 kilometers, and it wants to have such a high speed. , Then there must be a special train set. In addition to the power at the front, there must be power under the carriage.

As for the development of the Shinkansen train in the island country, the technology has been absolutely mature, and it has become a beautiful landscape in the island country. Other countries are jealous.

If there were such trains in Han, it would be great!

"So, do we need magnetic levitation technology?" someone asked.

Speaking of high-speed trains, magnetic levitation is a very attractive solution. This train technology is based on high-tech. It uses the magnetic field of superconducting coils to make the entire train fly on the track, so the resistance is The smallest, so the fastest, is considered a development direction.

Only Qin Guan knew that this kind of thing, sounded tall, it was a variety of problems when used, and it was definitely not the most suitable choice.

Now, Qin Guan heard the other party say this, and immediately shook his head: "No, no, we don’t want such advanced technology. What we want is a mature project that can be launched using existing technology. We want to build ordinary high-speed trains. It runs on the rails."

Qin Guan must correct this point of view for them, and don't think that the superconducting maglev train is going to be tall, that thing has fallen out of favor in later generations.

"Ordinary train?" Someone murmured, "We don't have any technical reserves!"

"Therefore, our North Industries Corporation has secretly imported a special high-speed train from abroad, which can provide you with a sample. However, we only give it to powerful companies. If no one can do it, I would I think it can be given to the northern heavy truck factory."

Generally speaking, there is no overlap between the unit that manufactures locomotives and the unit that manufactures heavy trucks. However, the North Industries Corporation is now the most prominent name, and the plan for the high-speed train was proposed by Qin Guan, so if If handed over to North Industries Corporation, it really feels like a matter of course.

Are you confident? In the absence of any contact, to imitate a train? Qin Guan is also a kind of radical method.

"Bring it to our CNR, our CNR is confident!" After Qin Guan finished speaking, someone immediately spoke.

In China, the unit that manufactures locomotives is separated from the north and the south. Although there are specific factory codes, they are called CSR and CNR by convention. Now, when Qin Guan said this, the people from CNR immediately called for war. Anyway, CNR is also called North Locomotive and Rolling Stock Factory, and it also has the word North. If it can be merged into North Industries Corporation through this research and development, it will be called Shuang Shuang, and the treatment there is quite good.

"Our CSR is confident, and we are more professional in manufacturing electric locomotives." When the people from CNR spoke, the people of CSR were certainly not convinced.

The scope of business is different. CNR mainly operates railways, while CSR mainly operates urban rail transit, etc. Although CNR is closer to high-speed trains, urban rail transit is definitely a proper electric locomotive. They are more experienced in operating electric locomotives.

Both companies are doing their part.

"Okay, okay, everyone don't quarrel." Seeing two important cadres, because this matter will have the possibility of quarreling again, the leader who presided over the meeting quickly stopped: "We don't care what we produce, That is all to build our motherland. Everyone has a sense of competition. This is great, but at the same time, we must also have the spirit of unity and cooperation.

Qin Guan shook his head: "No, I am more optimistic about them. There is competition to have vitality. There are two sets of locomotives we obtained from secret channels. We give each unit one set to see who can imitate them first."

Qin Guan prefers competition. Only when there is competition, there will be vitality. Look at the trains in Han. This is how they developed. From a toddler, to running back and forth on the land of the motherland, and finally going out of the borders to become Han. Qin Guan can see the spirit of a famous brand product of the train research workers.

At the meeting now, Qin Guan appreciates them very much. Compared to joint research and development, it is better to do their own things and see who can do it first.

"President Qin, we are here to make a military order, and CNR will definitely develop it first. We guarantee that there will be research results within one year."

"Our CSR was the first to develop it. We can complete surveying and mapping imitation in half a year!"

The two sides started again. Sure enough, Qin Guan was also having a headache this time. The host had the foresight and couldn't let them go on like this. The meeting became a quarreling vegetable market.

"Huh, you are all very capable. You can get it out next month. I just don't know. The smallest part on your locomotive is not as good as the bearing. Which manufacturer do you plan to find for it?" At this moment, a message appeared below. Weird sound of Yin and Yang.

"Old Li, whose station are you demolishing?" Someone suddenly became unhappy.

Qin Guan's eyes were bright. These people heard that they already had samples, and they were all vowed, but one person saw some of the technical difficulties.

For example, the simplest bearing.

The bearing is very simple. There are two circles on both sides, with a ball or a needle in the middle. The most common bearing in industrial products is an important component in high-speed rail gearboxes.

For high-speed EMUs, as long as the speed exceeds 200 kilometers per hour, the bearing accuracy needs to reach P5 and the limit speed is 3000 rpm. In fact, when the speed is 200 kilometers, it already belongs to the category of high-speed bearings.

Among them, the input shaft of the gearbox has a very high speed, reaching 6000 revolutions per minute. The bearings here are even more demanding. In addition to the high speed, it also has to withstand a lot of impact. This is not a normal bearing. As a result, there is no domestic bearing factory that can produce this kind of bearings.

In later generations, Han's high-speed rail became famous overseas, but the bearings on the high-speed rail were all imported. In order to change this status quo, the country is also determined to do research and development on its own, so as not to get stuck in this little equipment.

Of course, apart from the bearings, the entire gearbox is technically difficult. At high speeds, as long as the gears are slightly inaccurate, severe vibration will occur.
