Will China s high speed rail be defeated by Japanese technology in the future?

No one can say for sure what the future holds, but on the surface, the future is on China's side. On the one hand, China's science and technology have improved faster, while Japan has not made revolutionary progress. On the other hand, China has a market advantage, and the main basic investment in the future of the world is in Asia, and China is a founding member of the AIIB while Japan is not, so China has an advantage. However, it should also be recognized that Japan has established a good made-in-Japan brand advantage over the past few decades, and Japan's Shinkansen has a strong demonstration role as one of the earliest high-speed rail projects.

The main thing is that the current high-speed rail projects are concentrated in the United States, Latin America and Europe, and this part of the market does not have a high degree of recognition of China's high-speed rail, so China often needs low-cost and high-quality services, which leads them to think that Chinese products are unreliable (in fact, they are not as good as Japan and Germany). For example, last year's hyped export of China's subway to Boston, the United States, 284 subways with a 30-year service period of only more than 600 million US dollars, about 100 million yuan, a subway of more than 2 million US dollars and a 30-year warranty, in fact, the result of the internal fighting between China South Railway and North train, made foreigners see the joke. Domestic ** generally either reports the contract amount or only the number of subways, because a comparison is hehehe.

However, now that the two companies have been integrated, it may be better if they can check the economic problems of their CEOs.

No, Japan is in a state of decline High-speed rail technology has not made much progress in the past 20 years, and there are many deficiencies in maturity, and China's high-speed rail technology is not inferior to Japan, and the important thing is that China's high-speed rail is on the rise.

If the Chinese do not examine themselves and do not take their work attitude seriously, they will only shirk their responsibilities and conceal the facts when something happens. No matter how many years it takes, no matter how advanced technology China has, it can't compare to Japan's.

When China first introduced high-speed rail technology, it did absorb Japan's experience, but the imported technology was not a complete copy. Not to mention, the technology we absorb is not limited to Japan.

Moreover, Japan provided technical cooperation only when it wanted to get EMU orders, and it also put an end to high-tech cooperation, which has an expert's explanation on the Internet.

The Ministry of Railways' order for 140 EMUs is a condition of cooperation, requiring that the products must be manufactured by Chinese enterprises. In order to get orders, the giants (Siemens of Germany, Alstom of France, Kawasaki Heavy Industries of Japan, Bombardier of Canada) must choose to cooperate with Chinese companies and participate in the bidding through technology transfer.

In fact, the high-speed rail in foreign countries has a very short route and time. Our country is vast, the Beijing-Shanghai line alone, it takes 4 hours to run, and the Beijing-Guangzhou high-speed railway is more than 2,000 kilometers. This requires us to have higher high-speed rail technology, which has higher requirements for materials and structures, which means that our high-speed rail technology will progress faster.

So our own high-speed rail technology is definitely world-class, CCTV has a lot of documentaries about high-speed rail, it seems to be called a super project or a great high-speed rail.

High-speed railway, referred to as high-speed rail, refers to the railway tie-up system with high design standards and can be used for safe and high-speed travel of trains. The concept is not limited to tracks, nor does it refer to trains.

High-speed rail has different regulations in different countries, different times, and different scientific research and academic fields. The "Code for the Design of High-Speed Railways" issued by the State Railway Administration of China defines high-speed rail as a new passenger dedicated railway with a design speed of 250 kilometers per hour to 350 kilometers per hour and a standard gauge for EMU trains.

China's national *** defines China's high-speed rail as a new or existing line railway with a speed of 250 kilometers per hour and above, and promulgated the corresponding "Medium and Long-term Railway Network Planning" document, which includes some rail lines with a speed of 200 kilometers per hour into the scope of China's high-speed railway network.

At the same time, the "high-speed rail" is purely used by the private and China Railway Corporation's train ticket system (12306 official **) to refer to China's high-speed EMU passenger trains (G prefix trains), which is a wrong term.

On December 1, 2017, the "English Translation and Writing Specification in the Field of Public Service" was officially implemented, stipulating that the English name of the high-speed EMU standard is G-series high-speed train. On October 21, 2020, the 400km h cross-border interconnection high-speed EMU of "Advanced Rail Transit" rolled off the assembly line in CRRC Changchun Rail Passenger Car Co., Ltd.

By the end of 2020, the operating mileage of railways in China has reached 10,000 kilometers, including 10,000 kilometers of high-speed railways and 90,000 kilometers of railways in the central and western regions.

China's high-speed rail is not more advanced than Japan's, and it can only be said that the Shinkansen and CRH have taken a different direction of development.

It is not possible to simply compare the speed and smoothness of operation. The national railway's top priority is not economic efficiency but infrastructure construction, and the railway facilities are quite high, which can be reflected in the passengers' riding experience.

And because the Sunduan Shinkansen has to consider more economy and competition with aviation, it will pay more attention to the vehicles. The use of tilting trains to compensate for the lack of track configuration, China does not have tilting train technology, and focuses on solving the noise problem of train operation.

And not only is there no backwardness in technology, but also convenience and service. Each Shinkansen line is graded according to the number of stops, such as Tokaido's Nozomi, Hikari, and Echo.

The development of high-speed rail in our country

China's high-speed rail construction technology is in the forefront of the world, and this year scientists have made a major new progress, the theoretical speed of up to 1000 kilometers per hour of high-temperature superconducting high-speed maglev prototype in Chengdu at the beginning of this year, the train performance in all aspects is better than the Japanese Shinkansen. China uses liquid nitrogen for cooling, which is not only non-toxic and non-toxic, but also accounts for as much as 78% of nitrogen in the air, which greatly reduces the cost of train operation.

According to the current speed of China's high-temperature superconducting maglev train, Beijing to Shanghai only takes hours, faster than high-speed rail hours, and the research team of Southwest Jiaotong University is further studying vacuum pipeline technology, the running track of the vacuum environment will greatly reduce the running resistance, the train can reach 1000 kilometers, and it will no longer be a dream to Beijing to Shanghai in one hour.

1. The opening time is different.

1. Japan's high-speed rail: On October 1, 1964, Japan's first Tokaido Shinkansen was opened, connecting Tokyo, Nagoya and Osaka, connecting Japan's three major metropolitan areas.

2. China's high-speed railway: In May 1998, the electrification and speed-up transformation of Guangzhou-Shenzhen Railway was completed, with a designed maximum speed of 200 kilometers per hour.

Second, the speed requirements are different.

1. Japan's high-speed rail: 270 or 300 kilometers per hour, with a maximum speed of 603 kilometers per hour (L0 maglev train, 2015).

2. China's high-speed railway: a new passenger dedicated line railway designed to run 250 km-h (including reserved) and above EMU trains, with an initial operating speed of not less than 200 km-h.

Third, the characteristics are different.

1. Japan's high-speed rail: The Shinkansen adopts a decentralized operation mode instead of being pulled by a locomotive (locomotive). The so-called power dispersion means that the wheels of each carriage are equipped with a driving device, an electric motor, to distribute the power of the train to each carriage.

2. China's high-speed rail: The high-speed rail is very smooth to ensure safety and comfort. The high-speed railways are all seamless steel rails, and the high-speed railways with a speed of more than 300 kilometers per hour use ballastless tracks, that is, the overall track bed without stones to ensure smooth traffic; The high-speed railway has fewer curves, a large curve radius, and the turnouts are mobile high-speed turnouts; Viaducts and tunnels are widely used to ensure flatness and greatly reduce distances.

High-speed rail is a common means of transportation in people's lives, and the speed of high-speed rail is generally much faster than that of trains, which can effectively improve people's work efficiency. Japan's high-speed rail, compared with China's high-speed rail, will develop earlier. In the 60s of the last century, Japan's high-speed rail has gradually developed, and the current technology can be said to be relatively mature.

The development of China's high-speed rail was slightly later, but later through people's continuous improvement and innovation, China's high-speed rail technology has also achieved a great improvement.

If you look at it from a technical point of view, Japan's high-speed rail may be more advanced than China's high-speed rail technology. At present, the fastest speed of China's high-speed rail is 350 kilometers per hour, while Japan's high-speed rail speed has reached 600 kilometers per hour. Although Japan has developed a high-speed train with a speed of 600 kilometers per hour, it has not been successfully produced so far, and it may take a few years before it can be put into production and use.

I believe that in a few years, my country's high-speed rail speed will definitely improve, and even catch up with Japan.

In addition to the technical aspect, there are some gaps between China's high-speed rail and Japan's high-speed rail, and Japan's high-speed rail has more advantages than China's high-speed rail in the high-speed rail chain. Like some core components in the production of high-speed rail, China currently does not have the capacity to produce. Although China does not have Japan's core components, some of the technologies developed by China's high-speed rail itself are also very advanced, and the overall ** will be cheaper than Japan.

Even if there is still a small gap between China's high-speed rail and Japan's high-speed rail, this is also a normal phenomenon. After all, Japan's high-speed rail technology was developed decades earlier than China's, and China's high-speed rail technology has reached the current level under the premise of decades of late development. With the continuous progress of China's technology, it is believed that in the next few years, China's high-speed rail technology is likely to surpass Japan.

The development of high-speed rail in Japan in recent years is still very good, and it attaches great importance to the development of high-speed rail in thousands of years, and will also strengthen the construction of this aspect; Compared with China, there is still a very obvious gap, after all, China's development in high-speed rail is also very outstanding.

The development of high-speed rail in Japan is not very good; The speed is not as fast as in China, and the comfort is not very good, and it is relatively expensive.

It's not good, Japan's high-speed rail has not become popular on a large scale, so the development of high-speed rail is not perfect, and the amount is relatively small.

The high-speed rail is a complex system of engineering, consisting of a body part.

It is composed of parts, power supply parts, power supply parts, electronic control parts, bridge parts, tunnel parts, supporting facilities and other parts.

More than 20 years before the large-scale operation of China's high-speed railway, the world's high-speed rail from Germany, France and Japan has been successfully used, and their high-speed rail technology is also their own strengths, France is stronger in terms of body, Germany is more prominent in terms of electricity, and Japan has more advantages in electronic control.

You must know that the Chinese have a very deep foundation in these kung fu skills, and most of the more than a dozen bureaus built by China Railway were transferred from the original team of the former railway soldiers, who were once famous on the Korean battlefield, and at that time, under the indiscriminate bombardment of US Air Force aircraft, no matter how serious the damage to the railway was, it could be restored to traffic in a few hours.

Don't talk about Japan, the world in high latitudes, permafrost strata to build railways can not think, forced this group of people do not know much about the construction team to complete for many years, the facts have proved to run well, is its engineering and technical indicators need to be tested by Japan? No, the technical authority in this area can only be Chinese.
