China High-speed Railway is the first of the "Four New Inventions of China" in the minds of foreign youth, and it is also the "China specialty" that they want to take home most. In the eyes of many foreigners, China high-speed rail has a "high-value, high-speed and almost perfect ride experience ..."
High-speed rail has changed China and our lives. High-speed rail is becoming a business card of China, spreading its charm to the world. How did the high-speed train in China come from? Where is the "cow" of China high-speed rail? Can China High-speed Railway Run Faster?
Refreshing the "China Speed" of Cognition
It seems that "standing to coin but never failing" has become the most direct impression of foreigners on China high-speed rail. Earlier, a foreigner filmed a video of a coin standing on a high-speed train in China, which caused a heated discussion on the Internet. In this video, which lasted for several minutes, the train was running at a high speed, but the coins stood steadily all the time, which triggered a discussion among foreign netizens.
"I once took a high-speed train to complete a trip from Beijing to Xi 'an, and this experience simply refreshed my cognition! "Roger comes from the United States and has lived in Canada, Britain, Japan and China. He said that he likes both the urban light rail and the high-speed rail in China.
In China, foreigners call high-speed rail the best way to travel. Abroad, high-speed rail in China has also brought convenience and opportunities to local people.
Levent is a student of Turkish Culture University. In recent years, he paid attention to the cooperation between China and Turkey in high-speed rail construction: "There are many high-speed rail projects in Turkey, and China has provided a lot of help in these projects. I think Turkey and China have more opportunities for cooperation in these projects. "
The development of high-speed rail in China has also attracted the attention of foreign media. Last year, Russian Channel 1 released a series of documentaries called "Follow Ye Shuxuan to China". According to Ye Shu, the creator of the documentary, the first program introducing China high-speed rail received enthusiastic comments from many viewers. After taking the China high-speed rail, he also lamented: The China Harmony train is really a railway miracle!
The British Broadcasting Corporation (BBC) once regarded high-speed rail construction as a symbol of China's new industrial revolution in an article entitled "New Industrial Revolution in China". According to the article, the unique culture of China and the industrious innovation of the people of China have enabled the rapid application of high-speed rail technology in China and led the world.
Yonhap News Agency's statement is more straightforward: "You can really feel the speed of China by taking the high-speed train."
A continuous "high-speed rail revolution"
"It was an era of burning passion. Everyone is insisting that China high-speed rail must truly become China people's own high-speed rail. " Looking back on the innovation and development of high-speed rail in China, Jia Limin, a professor at Beijing Jiaotong University and head of the special expert group on advanced rail transit in the 13th Five-Year Plan, was filled with emotion. Since 1990s, Jia Limin has been devoted to the research and innovation of high-speed rail in China, and witnessed the whole process of the development of high-speed rail in China.
"We started from the shoulders of the West." Talking about the development of high-speed rail in China, Jia Limin said frankly that introducing, digesting and innovating western technology is very important for our development. From construction according to drawings to minor repairs, from introducing western manufacturing capabilities to forming their own core technology, China "high-speed rail people" spent more than 10 years "comprehensively and systematically" researching and building their own high-speed railway.
The construction period of Wuhan-Guangzhou high-speed railway is four and a half years, which generally takes 8- 10 years abroad. Wang Zhijian, chairman of Wuhan-Guangzhou high-speed railway, said: "We spend their rest time and tea and coffee time at work." Li Wanjun, a welder of CRRC Changke Co., Ltd., is known as "Worker Academician". Under his command, all the high-speed rail weldments have the same appearance and no flaws. In his eyes, "every weldment is a work of art". The Baolan high-speed railway, which took five years to build, has complex geology and landforms along the line, and was described by Yuan Tao, the project manager of Gansu section of Baolan high-speed railway of China Railway Second Bureau as "like building a high-speed railway on tofu". ...
The development of high-speed rail in China cannot be separated from the hard work of high-speed rail builders and the strategic support of the country. In Jia Limin's view, the successful development model of high-speed rail in China largely depends on China's institutional advantage: concentrate on doing great things.
"We have integrated the best technology and innovation forces in China, including more than 20 top domestic universities, more than 50 key laboratories and innovation capability platforms, and more than 500 supporting enterprises. From basic materials to control, from electronics to chemical industry, from machinery to information, we have made highly organized innovations in all fields involved. We have chosen a problem-oriented, goal-oriented and demand-oriented technological innovation path. " Jia Limin recalled that it coincided with the great development of high-speed rail construction in China, and the country provided valuable market opportunities and experimental verification environment for high-speed rail research and innovation: "We can do experiments when we have products, and we will be specially arranged to do experiments for a period of time before each new line is opened. Besides China, who else in the world has this opportunity? "
"Europeans call it the high-speed rail revolution in China, and this revolution continues." Jia Limin added.
The frontier is unique.
Due to the complex geological environment and climate change, the challenges faced by high-speed rail in China are incomparable in any part of the world. He Huawu, chief engineer of China Railway Corporation, said that the operating environment of high-speed rail in China is the most complicated, including high-cold high-speed rail, sandstorm-resistant high-speed rail and coastal high-speed rail, with long continuous high-speed transportation distance. "These factors determine the diversified demand for high-speed EMUs in China."
Therefore, Jia Limin and the high-speed rail innovation team put forward the concepts and technical framework of "high-speed train intelligence" and "high-speed train pedigree" for the first time in the world. Jia Limin compared the pedigree technology platform to an "old hen", which can "lay eggs" according to the actual demand, and complete the customization and demand-oriented rapid design, manufacture and delivery of high-speed train products. Under this pedigree platform, China has produced a series of high-speed train products suitable for plateau desert areas, such as intercity EMUs, plateau EMUs and alpine EMUs. The "Fuxing" launched on June 26th is also the application result of this technology platform.
China's high-speed rail construction has made remarkable achievements, from freezing areas covered with ice and snow to tropical islands, from extremely desert and windy areas to extremely dangerous mountainous areas. Wang Junbiao, a researcher in china academy of railway sciences, said that the overall technology of China Railway in terms of construction, operation and risk prevention and control has reached the world leading level.
Why does China's high-speed rail lead the world? Jia Limin said that China high-speed rail has the most complete technical and industrial support system in the world. "China can solve all the technical problems related to high-speed rail by itself. This kind of integrity is unique to China on a global scale. "
Jia Limin also admitted that we still have shortcomings to introduce in basic technologies and industrial fields such as materials, electronic components and basic components of information technology involved in high-speed rail, but this does not affect our independent innovation. Economic globalization can greatly alleviate the constraints brought by these shortcomings. "High-speed rail technology, design and standards are all formulated and mastered by us. We need to pay attention to the quality, efficiency and inclusive development facing the world. What we need is to integrate global resources without affecting the integrity of China's high-speed rail innovation capability and industrial capability system. "
Can high-speed rail "reach speed"?
It only takes more than five hours from Beijing to Shanghai, connecting the capital and economic center of China. It takes 2 1 minute to get from Beijing to Langfang, Hebei Province, which brings convenience to a large number of working-class people who "work across provinces" ... In the lead all the way, high-speed rail has become the new engine of China's economic development and brought great changes to the lives of people in China.
Spread out the map of China, we can see that the criss-crossing railway lines closely link China. In the past five years, China's high-speed rail has increased its operating mileage by1.2000 km, with a total mileage of more than 22000 km, exceeding the total operating mileage of other countries in the world. By 2025, China's high-speed railway network will reach 38 thousand kilometers, covering more than 240 medium-sized cities across the country, which will completely change the concept of distance and time and space on this land.
With a series of technological innovations, the speed of high-speed rail has been widely concerned by the society. "The test speed of Fuxing can reach 400 kilometers per hour, and the designed continuous running speed is 350 kilometers per hour, but why is the actual running speed still 300 kilometers per hour?" A Beijing resident expressed doubts about this. Can the actual speed reach the design speed? Can the test speed ensure safe driving? These problems have aroused the discussion of many netizens.
Jia Limin bluntly said that it is narrow-minded, short-sighted and lacking the overall situation to reduce the speed of high-speed rail on the grounds of safety without scientific and reasonable evaluation and to resist the speed on the grounds of cost. "Every link of high-speed rail from R&D, design to operation and maintenance adheres to the bottom line principle of fail-safe principle, that is, any failure must lead to safety side output. Our design speed is 350 kilometers per hour, which means that through our design process and technical means, the high-speed rail itself has the conditions and technical capabilities to operate safely under the condition of 350 kilometers. " Jia Limin said that relevant departments are now making every effort to prepare for the recovery speed.
