Looking back on our past decade, a series of national heavy weapons and super projects created by central enterprises have engraved new coordinates of national development from different dimensions. On September 12, "Our Ten Years @Coordinate China" online theme publicity was officially launched. With the continuous refreshing of China's span, Chinese accuracy, Chinese height, Chinese depth, Chinese strength and Chinese speed, it focuses on the representative major achievements in infrastructure construction and scientific and technological innovation since the 18th National Congress of the Communist Party of China, and demonstrates the courage, courage and wisdom of building builders of central enterprises to overcome difficulties and challenge the limits.
On July 20, 2021, the high-speed maglev transportation system with completely independent intellectual property rights was successfully launched. This is the fastest large-scale ground transportation tool that can be realized at present. Its launch marks that my country has mastered the complete set of high-speed maglev technology and engineering capabilities. What kind of unshakable belief is that allows us to constantly explore the peak of rail transit speed? How will our future change? What difficulties have we overcome in the process of continuous exploration? Today, Xiaoxin brings you the 26th issue of the theme film "Coordinate China" series, "China Speed" "Super Yi Juechen" .

Human pursuit of speed is endless From human and animal power to steam locomotives, internal combustion locomotives , electric locomotives, high-speed EMU People's land travel speed continues to rise from dozens of kilometers Fuxing EMU
has achieved a speed of 350 kilometers per hour
Now, we are still exploring
ml3
The peak of rail transit speed
Speed 600 kilometers per hour High-speed maglev comes in time
July 20, 2021
With completely independent intellectual property rights
Speed 600 kilometers per hour High-speed maglev transportation system was successfully launched in Qingdao
PART1
Why should we develop high-speed maglev?
China has a vast territory and a large population
Rapid economic development has driven
A large number of passenger flow, freight flow and fast commuting demand
High-speed maglev height conforms to my country's national conditions
Speed 600 kilometers per hour high-speed maglev transportation system
Can fill the gap in high-speed rail and space travel speed
form more in line with the formation of more integrated A multi-dimensional transportation architecture that is efficient, flexible and convenient.
improves my country's comprehensive three-dimensional transportation network
. The distance between
. The distance between
. 24 hours can be achieved to reach
. It can also realize the round trip on the same day.
PART2
. What are the new advantages of high-speed maglev?
High-speed maglev transportation system
Strong transportation capacity, green and environmentally friendly
It also has the characteristics of no contact with the track and no mechanical rotating parts, etc.
The vehicle body realizes the most ideal smoothing
can effectively reduce aerodynamic resistance
traction motor and traction flow conversion system on the ground
Can realize high-power high-speed traction
maintenance and maintenance volume is very small
low maintenance cost
good economy throughout the life cycle
cost performance high
faster speed
air resistance and noise
only Designing a suitable "head shape" and appearance
to minimize resistance and energy consumption
to reduce noise and vibration
High-speed magnetic levitation appearance design
comprehensively considering aesthetics, pneumatics, human-factor engineering and other factors
to compare more than 30 solutions
to finally determine the appearance solution
The seat with high-speed maglev is wide and comfortable,
The armrest is equipped with wireless charging, and it also has a curved back screen
Support audio and video entertainment and information query
In addition, there are a number of intelligent service functions such as electronic curtains
PART3
Flying on the ground, what difficulties have we overcome?
Speed 600 kilometers
What needs to be challenged is not just the threshold of speed level
High-speed maglev realizes
From system integration into vehicles, traction power supply
Operation and control communications, line tracks and other systems
Major breakthrough in complete set of engineering technology
solves html under ultra-high speed and complex climate and geographical conditions 3
Aerodynamics, suspension guidance, vibration reduction and noise reduction
Training and braking, operation control, rescue and escape, etc.
A series of technical problems
Take guidance as an example
High-speed maglev rail suspension gap is only 10mm
How to make multiple marshal trains suspend accurately Floating
and "flying on the ground" at a speed of 600 kilometers per hour
"floating stably" is a huge challenge
R&D team has repeatedly tried and optimized
for 5 years, and has tried more than 4,000 times html l3
Finally developed a fully autonomous
High-precision and high-stability suspension guidance system
Solve one of the core problems of the maglev system
" Powerful transportation country " grand blueprint
is slowly unfolding
