What technologies are inseparable from the planning of high speed rail?

What is little known is that the development of China's high-speed rail has been inseparable from a key technology - that is, lubricating oil. High-speed rail as a major high-tech equipment, the daily maintenance and guarantee of the gear box is inseparable from lubricating oil, and China in the initial stage of high-speed rail, for a long time is dependent on the import of related technology from Germany, Japan, the United States, but now we see the "Fuxing" has completely adopted China's independent research and development of the Great Wall lubricating oil, a change in the past too dependent on the "foreign oil" situation, it can be said that in the "Fuxing" a lot of domestic independent key technology, which is the future of China's high-speed rail technology to the world has a significant contribution.

The safety and comfort of high-speed rail is also the focus of Chinese attention, I have heard a high-speed rail technical engineer interviewed by reporters: he will be dizzy when taking any train, the reason is that the stability of the train at high speed is not enough, so it will cause body turmoil, now we want to build high-speed rail, the first thing to solve is the stability of the train at high speed. Through an experiment of standing coins in a carriage, we can see that this technology has met expectations.

Passengers who take the high-speed rail will have this experience: the journey is smooth, time-saving and labor-saving. Although it is slightly higher, its comfort is directly proportional to the price.

Increasing speed is an eternal theme in transportation. The plan calls for continuing to increase the speed of trains, and there are concerns that the faster the speed, the more dangerous it is. Speed is the independent variable of the large system of high-speed railways, and if the speed of the line is determined to be 350 kilometers per hour, then a standard system will be developed around ensuring the safe operation of trains at 350 kilometers per hour.

As long as the safety technology system and monitoring mechanism are implemented, the safe operation can be guaranteed."

It is very important to import, digest, re-innovate and develop Western technology. From drawing construction to minor renovations and repairs, from the introduction of Western manufacturing capabilities to the formation of their own core technologies, China's "high-speed rail people" have spent more than 10 years "comprehensively, systematically, and without missing a corner" to study and build their own high-speed railway.

The development of China's high-speed rail is inseparable from the hard work of high-speed rail builders and the strategic support of the state. In Jia Limin's view, the success of China's high-speed rail development model depends largely on China's institutional advantages: concentrating on big things.

The innovation of major powers and heavy weapons needs to give full play to the institutional advantages of "concentrating on doing great things". Break the battle of the door, give up individual interests, as the only buyer to focus on and selectively introduce the most advanced foreign technology platform, the manufacturing and R&D team clenched their fingers into a fist, open and interconnected, learn from others' strengths, for my use, form a late-mover advantage, and truly maximize the utilization efficiency of market resources and scientific research resources.

It integrates the best scientific and technological and innovation forces in the country, including more than 20 top domestic universities, more than 50 key laboratories and innovation ability platforms, and more than 500 supporting enterprises. From basic materials to controls, from electronics to chemicals, from machinery to information, we carry out highly organized innovation in all areas involved.
