Super Weapon Swap System

"Mr. Qin, do you mean the high-speed train of Shinkansen in island countries?" someone asked a question below. Everyone is engaged in railways. Speaking of this, of course, everyone knows.

Qin Guan nodded: "yes, you can understand that."

As for the high-speed train, 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 exceeded 300 km. If you want to have such a high speed, you must have a special train set. In addition to the power at the front, there must also be power under the carriage.

As for the development up to now, the technology of this Shinkansen train in the island country has been absolutely mature and has become a beautiful scenery in the island country, which is envious of other countries.

If there were such trains in the Han country, how good it would be!

"So, do we need maglev technology?" someone asked.

Speaking of high-speed trains, maglev is a very attractive scheme. This train technology is based on high technology. It makes the whole train fly on the track through the magnetic field of superconducting coil. In this way, the resistance is the smallest, so the speed is the fastest, which is considered to be a development direction.

Only Qin Guan knows that this kind of thing sounds big and big. It is a variety of problems to use. It is definitely not the most appropriate choice.

Now, hearing what the other party said, Qin Guan immediately shook his head: "no, no, we don't want so advanced technology. What we want is a mature project that can be launched by using the existing technology. We want to build an ordinary high-speed train and run on the railway track."

Qin Guan must correct this view for them. Don't think that the superconducting maglev train is tall. That thing has fallen out of favor in future generations.

"Ordinary train?" someone murmured, "we don't have any technical reserves!"

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

Generally speaking, there is no intersection between the unit manufacturing locomotives and the unit manufacturing heavy trucks. However, the North Industrial Company is now the most famous, and the plan for the bullet train was put forward by Qin Guan. Therefore, if it was handed over to the North Industrial Company, it would be a natural feeling.

Do you have confidence? Without any contact, go to imitate a train? Qin Guan is also a method of motivating the general.

"Give us CNR, we CNR have confidence!" Qin Guan said, and someone spoke immediately.

In China, the units that manufacture locomotives are separated from the north and the south. Although there are specific factory codes, they are conventionally called CSR and CSR respectively. Now, when Qin Guan said this, the people of CSR immediately asked for war. Anyway, CSR is also called Northern Locomotive and rolling stock factory, which also has the word north. If this research and development, It's cool enough to be incorporated into the northern industrial company. The treatment there is quite good.

"We CSR are confident that we can make electric locomotives more professionally." hearing the people of CNR speak, the people of CSR are certainly not convinced.

Our business scope 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 proper electric locomotives, so they have more experience in operating electric locomotives.

Both companies are committed.

"All right, all right, let's stop arguing." seeing that two important generals might quarrel again, the leader presiding over the meeting quickly stopped: "No matter what we produce, it's all for the purpose of building our motherland. It's good that everyone has a sense of competition, but at the same time, we should also have the spirit of unity and cooperation. We can't always fight like this."

Qin Guan shook his head: "no, I'm more optimistic about them. Only when there is competition can there be vitality. There are two groups of locomotives we get from secret channels. We'll give each unit a group to see who can copy them first."

Qin Guan prefers competition. There is competition before there is vitality. Looking at the development of motor cars in the Han country, Qin Guan can see the spirit of train researchers from toddler to running back and forth on the land of the motherland, and finally going out of the national border to become a famous brand product in the Han country.

Now at the meeting, Qin Guan appreciated them very much. Compared with joint research and development, it's better to do their own work and see who can do it first.

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

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

The two sides started again. Sure enough, Qin Guan will have a headache this time. The host has foresight. They can't go on like this. The meeting has become a quarreling vegetable market.

"Hum, you are all very capable. You can get it out next month. I just don't know. The smallest part of your locomotive is not as good as the bearing. Which manufacturer are you going to find?" at this time, a strange voice appeared below.

"Lao Li, whose platform are you dismantling?" suddenly someone was unhappy.

Qin Guan's eyes lit up. These people heard that they had samples and vowed to do it. However, one person saw some of the technical difficulties.

For example, the simplest bearing.

Bearing is very simple. There are two circles on both sides, with ball or needle roller in the middle. It is the most common bearing in industrial products and an important component in high-speed railway gearbox.

As long as the speed of high-speed EMU exceeds 200 km / h, the bearing accuracy needs to reach grade P5 and the limit speed is 3000 rpm. In fact, when the speed is 200 km, it already belongs to the category of high-speed bearing.

In particular, the speed of the gearbox input shaft is very high, up to 6000 rpm, and the bearing here is even more demanding. In addition to the high speed, it also has to bear a great impact, which is not what ordinary bearings can do. Even, no bearing factory in China can produce this kind of bearing.

In later generations, Han's high-speed railway was famous overseas, but the bearings on the high-speed railway were imported. In order to change this situation, China is also determined to do its own research and development, so as not to be stuck by this small equipment.

Of course, in addition to bearings, the technical difficulty of the whole gearbox is very great. At high speed, serious vibration will occur as long as the accuracy of the gear is not high enough.
