August 9th
The first domestic rare earth permanent magnetic floating rail transit project test line
—— "Red Rail" is officially completed
And realize the combination of rare earth permanent magnetic floating technology with air rail technology
Build a low -speed and low -speed transportation volume
New system rail transit system
my country is the third country that masters air rail technology
The test line of the two technologies of "magnetic floating+air rail" this time
It is the world's starting
Test line
New type of rare earth permanent magnetic floating rail transit system
Jiangxi Institute of Technology first proposed and led to research and development in 2014
In 2021
China Railway Sixth Hospital, China Railway Industry and other companies
Undertake the construction of the technical achievements
my country has completely independent intellectual property rights
Today, He Xiaoxin
Know this "China Intelligent Manufacturing" transportation system together!
01
The "Xingguo" born in "General County"
The "Red Rail" test line starts from Yongfeng Station in the south (high -speed rail Xing Guoxi Station)
Northern to Jingjun Library
The total length of the positive line is about 800 meters
All steel structures
Magnetic floating train adopts 2 vehicles
The passenger capacity is 32 seats and 88 members
The highest design runs is 80 kilometers per hour
This demonstration line is in Xingguo County, "General County" in the old revolutionary district
Known as "red rail"
The magnetic floating train is named "Xingguo"
The body consists of red and white colors
There are 56 stars on both sides of the car
The implication is owned by Xingguo County, "General County"
56 founding generals pay tribute
02
New -made rail transit from the "Rare Earth Kingdom"
Magnetic floating train relies on magnetic pole scolding or phase suction mechanism
Overcoming gravity and generating suspension effects
Use electrical magnetic magnets
Magnetic floating train with suspension effect
Magnetic magnetism changes with the size of the excitation current
Greater energy consumption
At the same time
Relying on complex control technology to achieve suspension
It will increase the difficulty of technology and operation and maintenance
The permanent magnet suspension is permanent magnet
(Can maintain its magnetic magnets for a long time)
To produce a suspension effect
That is, the permanent magnet and the rail scolding
Keep running in the middle line of the slot
Electromagnetic orientation and suspension can achieve zero mechanical friction operation
Therefore, find magnetic stability
The density is high enough, the magnetic is strong enough
And meet the permanent magnet of the train suspension needs
It has always been a alternative to the scientific and technological community
The emergence of rare earth permanent magnetic floating trains
Solved this problem
The current research results show
Relying on the alloy materials of rare earth elements
Can make small volume
The permanent magnet with high magnetic density and sufficient suspension. This is difficult to achieve natural magnet ore materials
"Red Rail" permanent magnet magnetic floating traffic system adopted
The permanent magnet is 钕 iron boron alloy
One suitable for magnetic floating transportation system
Rare earth permanent magnet alloy material
Strong magnetic and stable magnetic
The characteristics of magnetic energy distribution are reasonable
And rare earth element 硼 and boron natural reserves are high
Therefore, the cost is low
Make permanent magnet with rare earth materials
Jiangxi has a unique advantage
Ganzhou, Jiangxi is known as the "Rare Earth Kingdom"
It is one of the three major rare earth production bases in my country
70%of the world's 70%medium -weight rare earth
Application of rare earth permanent magnetic floating trains
Application model for my country's rare earth industry
Marketing is of great significance
03
Permanent magnetism with independent property rights
Permanent magnetic floating technology
Cover the permanent magnet material and rail transit
Multiple strategic emerging industries such as artificial intelligence
Following the constant -directed magnetic suspension, ultra -conducting magnetic suspension
Another new type of rail transit mode for development
Have complete independent intellectual property rights
At present, domestic air rail projects under construction are wheeled air rails
In contrast, permanent magnet magnetic floating air rail
Don't rely on rubber wheels
Can achieve zero friction operation
The characteristics of non -contact and suspended operation
The ability to climb is stronger and more energy -saving
Compared to Chang Dao Magnetic Floating Communication
Permanent magnetic floating empty rail
Has the characteristics of static magnetic field and "zero power" suspension
During the operation, the exhaust gas emissions and electromagnetic radiation are not generated during the operation
No harm to the human body and environment
The advantage of magnetic pollution is obvious
These advantages
Make the permanent magnetic floating empty rail more flexible
Not disturbed by other transportation
Not only applied to
City, scenic spots, airport connection
Commercial environments such as business center, characteristic town
On the river, around the lake, the seaside, high cold, desert, etc.
Under difficulty conditions, you can also show your skills
04
Collect a number of intelligence in one body
"Red Rail" from rare earth permanent magnet suspension system,
Driven driver system,
Intelligent positioning and communication signal system,
Operating control and security guarantee system,
Rail support and traction power supply system,
Vehicle, equipment system, etc.
Six most of the composition
It pioneered independence
Chang Dao's suspension and superconducting suspension
New system of magnetic suspension technology
The system has applied unmanned driving, Beidou positioning,
5G communication, sensing fusion, etc.
New theory, new technology, new methods
It has economical, safe and efficient, flexible maneuverability,
Good applicability, ecological environmental protection and other advantages
The independent intellectual property system is initially formed
A series of basic theories are forming,
Key technology, product standards, technical specifications
It will lead my country's new system, access -level rail transit
Open a new page
05
Safe and environmentally friendly "red rail"
"Red Rail" vehicles are hung under the floating rail
Like a "roller coaster"
Some people may worry about their safety
In fact, a mature air rail system
The "Red Rail" vehicle is wrapped in the rail beam
There is no possibility of derailment
And in terms of structure, traction, braking, control, etc.
There are reliable verification and redundant
Safety and guarantee
also
Due to the use of permanent magnet suspension technology
"Red Rail" can make the train suspend it without electrical energy
Energy -saving "worry -free" and environmentally friendly
my country's rare earth resources are abundant
The reserves and output are at the forefront of the world
Drive through major engineering applications
Extend the rare earth industry chain
Promote the sustainable development of the rare earth industry
"Red Rail" manufacturing materials can achieve circulating
Permanent Magnetic Floating Air Rail Project
Explore a medium and low volume that can adapt to complex terrain
Personalized, intelligent transportation methods
It will not replace the subway
It can be supplemented with the subway and light rails--
The subway is a large luck rail transit
The function is to ensure the large passenger flow transportation of the main network
The permanent magnetic floating empty rail is small and medium -sized transportation volume
Apply to capillaries
It can be used as a supplement to the subway
Further improve the comprehensive traffic network
At present, permanent magnet suspension air rail project verification
Successfully completed
Further optimize the car -track -magnetic rail
After the study of matching and coupling relationship
You can apply on a large scale
Looking forward to this one to check in this one
