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
