recently
The commendation meeting of the "National Engineer Award" was held
50 teams were awarded
The title of "National Excellent Engineer Team".
Fuxing high-speed train R&D and innovation team
is one of them
The Fuxing has carried passengers in total
More than 2.2 billion people
The Fuxing high-speed train is independently developed by China
A new generation of high-speed trains with full intellectual property rights
It is a major achievement of China's scientific and technological innovation
As of now, the Fuxing high-speed train
The cumulative number of passengers transported has exceeded 2.2 billion
At the end of 2012, the Fuxing high-speed train was launched
In 2017, with a maximum speed of 350 kilometers per hour
Make China the world's fastest commercial operation of high-speed rail
The fastest country and remains so far
This is exactly what the R&D team has been trying to do repeatedly
The results of continuous overcoming difficulties
China State Railway Group Co., Ltd
Engineer Zhou Li introduced
"The EMU that was introduced at that time
There are different types and standards
One driver has to drive many types of vehicles
Different trains cannot rescue each other
Repair parts, parts and devices are different
Brings a lot of technical problems in use"
Led by China State Railway Group Co., Ltd
United Nations domestic production, academia and research institutes
Form a R&D and innovation team
Pull the whole industry chain
Thousands of core supporting enterprises participated
Started the Chinese standard high-speed
The road to the development of EMUs
More than 500,000 parts!
China's standard EMUs started from scratch
After more than five years of breakthroughs and innovations
High-speed EMUs are highly complex
Extremely high requirements for security
Mechatronics products
A high-speed train with a speed of 350 kilometers per hour
Consists of more than 500,000 parts
Covering machinery, metallurgy, materials, power electronics
Chemical industry, information control, computer, precision instruments, etc
Numerous technical fields
Plus unique to the mainland
Road network patterns and geo-climatic conditions
Independent research and development of high-speed trains
Facing unprecedented challenges
"There are a lot of EMUs abroad
From start to finish, it's basically three or four hours
Chinese EMUs run for more than ten hours
are all very common
From Harbin, Heilongjiang to Guangzhou, Guangdong
Operates over long distances at different temperatures
It's unique
That's where we need to design
EMUs that are suitable for China's national conditions," Zhou Li said
In order to achieve the unification of the operating handle
The R&D team selected from more than 20 design proposals
After tens of thousands of demonstrations, tests, and experiments, it was finalized
With the unremitting efforts of the team
In June 2015, two Chinese standard EMUs
Successfully assembled, debugged and rolled off the production line
Subsequently, the test verification work was carried out
November 2016
Chinese standard EMU prototype
Complete 600,000 kilometers of application assessment
It's the equivalent of running 15 laps around the globe
June 2017
Chinese standard EMUs
Officially named "Fuxing"
It debuted in both directions on the Beijing-Shanghai high-speed railway
In September of the same year, the Fuxing EMU
Operates at a speed of 350 kilometers per hour
It is a commercial operation for the world's high-speed railways
Setting a new benchmark
After all R&D personnel
More than 5 years of technical research and independent innovation
The mainland finally broke through traction and braking in an all-round way
Core systems such as networks, car bodies, bogies, etc
and key technologies such as wheels and axles
China's high-speed rail has been built from scratch
From the introduction, digestion, absorption and innovation
to independent innovation
Now it leads the world
Constant speed 400 km / h
The new generation of EMUs is being developed and innovated
Laboratory at the China Academy of Railway Sciences
The team is currently ongoing
CR450 (High Speed EMU) Innovation Engineering Practice
Faster development and more energy saving
A new generation of EMUs that are more environmentally friendly and safer
Further lead the development direction of the world's EMUs
Zhou Li introduced, "The goal of the CR450 is:
Constant speed of 400 km/h
Higher requirements are placed on braking
Stop at a faster speed
These are the things that are being studied right now."
Today, nearly 1,200 groups of Fuxing
Mercedes in the vast land of the motherland
Possess "Chinese technology" and create "Chinese speed"
Realize "Intelligent Manufacturing in China"
Fuxing to establish "Chinese standards".
Become a beautiful "Chinese business card"
