Chapter 483 of the main text volume!? Mu Yang wants to do a high-speed rail with a speed of 500 kilometers per hour. This 500 kilometers per hour does not refer to the maximum speed, but refers to the normal operating speed, that is, the designed speed.

The maximum speed may have reached more than 600 kilometers per hour, which can be called "advanced high-speed rail".

The Wuhan-Guangzhou high-speed railway train is designed to have a speed of 350 kilometers per hour, and the train's maximum speed is 380 kilometers per hour. In actual operation, the average speed can reach less than 350 kilometers per hour, which is good if it reaches 300.

Mu Yang's design requirements are 42% higher than the design speed of 350 kilometers per hour, which is not outrageous. This technology is available in his Achievement Point Store. There are many types of train technology with a design speed of more than 500 kilometers. It is just that it is not suitable for the current national conditions of Hua Kingdom.

There are even vacuum magnetic levitation train technology with a speed of more than 4,000 kilometers per hour, which has reached a terrifying speed of 20,000 kilometers per hour.

Muyang wants to run a high-end high-speed rail, but there is a whim.

In his previous life, he often took the high-speed train back to his hometown. It took eleven hours to take from H City to Guicheng. In addition, the road was tossing, and the day passed, and it took two days to go back and forth.

If it is an ordinary train, it will take more than 30 hours. During the Spring Festival, it is too troublesome. I guess many young people have never experienced the scene of taking a green train to go home during the Spring Festival. They cannot buy tickets. The carriage is full of passengers, and they have no seats to stand. It is not convenient to move. It is difficult to go to the toilet. They have to hold back their urination and defecation, but they can only stand, but they are not convenient to move. It is difficult to go to the toilet and have to hold back their urination, let alone eat. It is expensive.

In recent years, the public's economic level has improved and he is willing to spend money to take the high-speed train.

If the high-speed rail envisioned by Muyang can be realized, the eleven-hour train time can be shortened to five or six hours, and you can still have dinner with your family when you walk at noon and arrive in the afternoon. This speed is actually more convenient than taking a plane, and you don’t have to worry about it like taking a plane.

You have to take a bus from the city to the airport by plane. The security check and waiting time are too long.

Of course, Muyang's desire to develop a high-speed rail was not just a whim. He really wanted to do something that benefits the people.

The speed of high-speed rail benefits hundreds of millions of people, but it is not just about charity, but only helps some people.

Muyang’s high-speed rail dream has many advantages.

One of the most important advantages is compatibility, which can be compatible with the existing railway network, that is, existing high-speed rail tracks do not require additional track laying.

Of course, if wide rails are used, it will be more stable and faster.

But it would be better to be compatible.

If it is not compatible, Muyang might as well be a magnetic levitation train. Although the Shencheng Pudong high-speed maglev train that has been opened to traffic is 430kh, this speed is not faster than the high-speed train, and the investment cost is high and it is not worth it. In addition, it is compatibility issues and weak technology, which has led to the Hua Kingdom eliminating the maglev trains out of the market.

But it is undeniable that magnetic levitation trains have some advantages that high-speed rail does not have, such as energy saving, simple maintenance, low noise, etc.

In Muyang's Achievement Point Store, there are technologies for maglev trains to run at a speed of 700 kilometers per hour. If the country had such technology before 2004, it would definitely not be as popular as the high-speed train with a speed of 350 kilometers per hour.

Muyang's high-end high-speed rail also faces many problems.

For example, the problem of stopping the station is whether workshops in small cities can be stopped. If such small stations can be stopped, they can drive local economic development and benefit more people; but if the stations are stopped, the speed will definitely drop.

Therefore, Mu Yang felt that this was not only a problem with the power system, but also a problem with the allocation of the high-speed rail operation system. If passengers are directly from Guicheng to BJ Station, there is no need to stop the station in the middle, and the speed is faster.

There is also the most important issue for the public, that is, ticket pricing, which is also the most critical issue.

The biggest reason for the lack of popularity of magnetic levitation trains is the fare.

For ordinary people, taking a car is shortened from ten hours to five hours. If the car is denied too high, they will not choose to take a ride. They can save two or three hundred yuan by sitting for a few more hours. Most people are happy and can’t make this money even if they work for a day.

certainly,

As the train speeds up, tickets for ordinary trains are not that tight. Even during the Chinese New Year, you can still get tickets for ordinary trains.

It is a problem of money for the people, and the test for the railway system is also very great.

Even if Muyang's advanced high-speed railway is developed, it will take a long time to verify safety by just a trial operation.

When new things are released, they always take a long time to verify and accept, and there are various obstacles, but innovation cannot be given up.

Mu Yang told his wife about his thoughts. After listening to them, Song Xuelu did not immediately comment. After thinking for a while, she first said as an ordinary person: "Honey, your idea is very good, it is beneficial to the country and the people.

Everyone hopes that the journey will be shorter and the journey will be faster;

As for the fare, it is normal to be more expensive than the high-speed train at the beginning, but many people will choose. I think the fare is within the scope of acceptance by the people.

I remember that when the EMU was first opened, most people couldn’t accept the fare, but over time, the income of ordinary people increased, and they could gradually afford second-class seats worth four or five cents per kilometer.”

Mu Yang's determination became stronger.

The biggest cost of building a high-speed rail is the line construction cost. The cost of a high-speed rail line with a speed of 350 kilometers per hour is 100 million yuan or 200 million yuan per kilometer. If a high-speed rail with a speed of 500 kilometers per hour can use the same track, the cost of this line is quite cost-effective.

If it is magnetic levitation, it will cost more than 200 million per kilometer, or even higher.

The second largest cost of high-speed rail is vehicle depreciation and maintenance. The current standard cost of a 350-kilometer-level EMU is about 170 million yuan, while the most expensive cost of the Harmony CRH380B is about 380 million yuan, and the CRH380A is about 300 million yuan, with a service life of 20 years.

Of course, compared with the Harmony, Fuxing is real, and the cost of independent research and development and manufacturing is much lower.

Other costs, such as labor, electricity bills, maintenance costs, etc., are much lower than line construction costs and vehicle costs.

Xinghai Group independently develops and manufactures new high-speed trains, and the cost is not too outrageous.

Companies such as Zhongche are already manufacturing high-speed trains. Muyang does not intend to occupy this high-speed rail market. In the future, they will cooperate with Zhongche and authorize the technology to earn back the R&D expenses. His ultimate goal is to benefit the people.

Of course, if you export, you will definitely make money, which is another matter.

With Muyang's economic situation, investing 10 billion yuan in super-advanced high-speed rail projects is enough. Most of this investment will be used to build test tracks. In contrast, a train sample cannot cost much money, just use it to play with a big toy. If the test is successful and popularized, it can at least benefit the country and the people.

Generally, companies cannot play such large projects, the investment is too large, and the return cycle is too long.

After several years of cultivation, Huaguo has indeed had the capacity to produce and manufacture EMUs on a large scale, but the key components of the EMUs that are claimed to be independently produced by Huaguo enterprises are still imported from abroad and are only assembled in Huaguo.

However, high-speed rail bearings, one of the key components, have been solved by Xinghai Group and do not need to be imported again.

There are only three core technologies of the train: traction system, bogie and braking system.

Among them, the most important thing is the traction system, among which Xinghai Group has the foundation for traction motor technology, but this technical content is relatively low.

The most core and most technical content in the entire traction system is the software system. Nishiko, Kawasaki, and Aarstom have not transferred this technology, and it also accounts for 20%-30% of the total price of a EMU.

Only by mastering the train control system can you set the parameters of each component and have real design capabilities, such as modifying the width of the vehicle and the high flow line.

Similarly, the high-speed rail braking system is monopolized by Knoll, and the core technology is not transferred.

Among the three major systems, the technology transfer contract was signed for bogie manufacturing, which only sold installation drawings and did not discuss design principles. Hua Guo did not know why.

In the introduction of high-speed rail technology, Hua Guofang created and gave up his huge

The market is the one that really makes high profits at the top of the pyramid. They take the initiative by controlling core technologies and key spare parts.

High-speed rail has created miracles, but it is indeed a big pain point for Huaguo's manufacturing industry.

The foreigners exclaimed on the Huaguo High-speed Railway, and we were still proud. There were many reports that the country had been able to independently develop and produce and no longer rely on imports.

This sentence is correct.

The train is indeed not imported and is manufactured by companies such as car companies. But what about the core technology?

Or buy someone else's.

Therefore, if Muyang wants to develop high-end high-speed railways, it must solve the core technology and switch from import to real independent research and development.

In addition, Mu Yang did not want to give up the vacuum pipeline magnetic levitation train, and it was really made and put into operation. Not to mention the speed of 20,000 kilometers per hour, as long as it exceeds the speed of 1,000 kilometers per hour, air transportation can really be eliminated.

Some institutions are currently studying this technology, but no results have been made.

There are many difficulties in construction and operation, such as how to pump air, how to seal, how to connect and isolate, etc. The number of words is not large, but the amount of technical information is very large.

If these problems can be solved, the biggest problem in the end is construction costs. With the prices in the next two years, a kilometer may cost about 400 million yuan. This budget is not a fool's guess, but a basis.

The vacuum pipeline of the vacuum pipeline of the magnetic levitation train can be built on and off the ground. At such a high speed, even if high-strength glass is installed, the naked eye cannot see the scenery outside the window. Therefore, if you really plan to take such a train, passengers will have to give up the idea of ​​enjoying the scenery along the way.

The above ground can be constructed by elevated pipelines. With other factors, it is more expensive than building elevated bridges. With the price in the next two years, the cost will be about 200 million yuan. If the underground is used to bury pipelines, according to the current cost of subway tunnels, if it is built in a city, the cost should be about 400 million yuan per kilometer.

The cost here and the cost of high-speed rail both refer to two-way and two-lane lanes.

The laying of the magnetic levitation train tracks of vacuum pipelines does not need to be separated from each other like highways or high-speed rails, because they are closed pipes and cannot affect the surrounding environment. The same base can be used, which is much lower in construction costs, but Muyang estimates that the comprehensive cost of two-way and two-lane is about 400 million yuan.

Even if vacuum pipeline magnetic levitation trains can be widely popularized, the fare will definitely be more expensive than second-class high-speed rail seats. This is certain. Otherwise, who would take the high-speed rail, but it would not be ridiculously expensive. After all, its construction and operating costs are not much higher than those of high-speed rail.

By the end of 2014, the operating mileage of Huaguo High-speed Railway reached 15,000 kilometers, and it increased at a growth rate of several thousand kilometers per year.

A few years later, the national high-speed railway has become a foregone conclusion. Even if Muyang creates a vacuum pipeline magnetic levitation train, it will be more difficult to popularize it, and it will not be possible to replace the high-speed railway in a short period of time.

But if we do it earlier, the country may give up on continuing to vigorously build high-speed rail and focus on vacuum pipeline magnetic levitation trains.

The next day, Muyang bought the technology of super high-speed rail and vacuum pipeline magnetic levitation train. The super high-speed rail spent 150 achievement points, while the vacuum pipeline magnetic levitation train spent 500 achievement points, which is the most expensive technology.

Mu Yang's total achievement suddenly shrank to 950 points, and he felt that his wealth had dropped drastically. It took about half an hour, and Mu Yang absorbed two technologies.

After a deep understanding of these two technologies, I found that the technical complexity of super high-speed rail is not as good as that of five-axis linked CNC machining centers, and is far inferior to its EBL lithography machine technology.

Achievability is not difficult. It mainly solves the power system problem and requires redesigning the train instead of imitating the previous Harmony train. For example, the chassis is lower, and the self-confirmed track identification centering function and lane keeping function, as well as the balance and stability system, appear more intelligent. In this way, the train can be ensured to be faster and safe and stable.

In terms of materials and manufacturing technology, Xinghai Group already has this condition. As long as the drawings are out, it can test-build a sample car.

The technical difficulties of vacuum pipeline magnetic levitation trains are indeed much more difficult than EBL lithography machines. The main difficulty is how to maintain the train chassis and tracks under ultra-high speed conditions.

The gap stability between the two ensures that the train does not collide with the pipe.

There are still many technical difficulties, but after Mu Yang thought about it, he felt that it was still possible. If other companies were to hand over the technology, they still had no ability to manufacture it.

At the same time, relying on powerful software systems and computing capabilities, Fortunately, Xinghai Group solved the problem of top chips.

He has two skills, and there is no conflict.

He predicts that high-end high-speed rail can achieve prototypes within one year, while vacuum pipeline magnetic levitation trains will be difficult to successfully test without three years.

Even if it is successful, the vacuum pipeline magnetic levitation train will have a higher fare due to its high cost. It is mainly used between developed cities. Perhaps in more than ten or twenty years, it will be popularized throughout the country like the high-speed rail, and replace the high-speed rail. After Mu Yang understood the two technologies, he was very excited and wanted to create the two trains immediately.

That night, Mu Yang told his wife about his ideas, and he rarely communicated with his wife about the planned and developed projects.

Song Xuelu was surprised:

"The air transport industry will not be eliminated in a short period of time, and it will take a long time to popularize portals. However, if the high-end high-speed rail is launched, the air transport industry will also be severely hit. "Mu Yang replied seriously, this is no joke.

Every time Xinghai Group launches innovative technologies, it will hit the same industry very hard.

With the launch of EBL lithography machine, ASLM executives all wanted to eat Mu Yang, and wished Mu Yang died early.

Therefore, the significance of vacuum pipeline magnetic levitation technology is similar to the original replacement of horsepower by steam engines, which will bring epoch-making changes. Civil aviation and railway transportation will be replaced by large areas, and human beings will enter a cleaner and more efficient travel era.

If these two technologies are established, they cannot be concealed because they need to build tracks and infrastructure for experiments.

By then, if the outside world knows about Xinghai Group’s project, it is estimated that the whole world will be lively.

I don’t know what obstacles Muyang and Xinghai Group will face.
