ABSTRACT

As the world continues to grow and as cities continue to become more crowded and congested, our normal modes of transportation will not be able to handle these overpopulated areas. The answer to this transportation problem lies in the world of electro magnetism and superconducting magnets. Electromagnets and superconducting magnets have allowed us to create a magnetic levitating train nicknamed “MAGLEV” that floats on the track instead of being directly on it. This has a lot of potential to create trains that are super fast with low maintenance requirements. China is the first country in the world to commercially use MagLevs, and has already helped ease the congestion on the six lane highway leading from the Pudong Shanghai International Airport to Shanghai Lujiazui financial district. This new technology has already helped China in a short period of time and can certainly help other cities around the world that are just as congested as Shanghai.

INTRODUCTION

Transport along with communication, forms the core of day to day life of modern world. Conventional rail transport through wide spread is now being considered inefficient in terms of fuel consumption and is time consuming. A genuine replacement for railways which is not only fuel efficient but also highly comfortable and can attain unimaginable velocities of around 450 – 500kms/hr are Maglev Trains whose idea was given by Robert Goddard, an American Rocket scientist, in 1904 who gave a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years, but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing.

The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be levitated above its track, or guide way, and propelled forward. Wheels and moving parts are eliminated on the Maglev train, allowing the Maglev train to essentially move on air without friction.

MAGNETIC LEVITATION SYSTEM

Magnetic levitation means “to rise and float in air”. The Maglev system is made possible by the use of electromagnets and magnetic fields.
The basic principle behind Maglev is that if you put two magnets together in a certain way there will be a strong magnetic attraction and the two magnets will clamp together. This is called “attraction”. If one of those magnets is flipped over then there will be a strong magnetic repulsion and the magnets will push each other apart. This is called “repulsion”. Now imagine a long line of magnets alternatively placed along a track. A line of alternatively placed magnets on the bottom of the train. If these magnets are properly controlled the trains will lift of the ground by the magnetic repulsion or magnetic attraction. On the basis of this principle, Magnetic Levitation is broken into three main types of suspension or levitation, they are –

1. Electromagnetic Suspension.
2. Electrodynamic Suspension.
3. Inductrack.

ADVANTAGES OF MAGLEV TRAINS

Magnetic Fields

Intensity of magnetic field effects of Maglev is extremely low (below everyday household devices)
Hair dryer, toaster, or sewing machine produce stronger magnetic fields

Energy Consumption

Maglev uses 30% less energy than a highspeed train traveling at the same speed. (1/3 more power for the same amount of energy)

Noise Levels

No noise caused by wheel rolling or engine
Maglev noise is lost among general ambient noise
At 100m – Maglev produces noise at 69 dB
At 100m – Typical city center road traffic is 80 dB

Vibrations

Just below human threshold of perception

Power Supply

110kV lines fed separately via two substations

Power Failure

Batteries on board automatically are activated to bring car to next station
Batteries charged continuously

Fire Resistance of vehicles

Latest non-PVC material used that is non-combustible and poor transmitter of heat
Maglev vehicle carries no fuel to increase fire hazard

Safety

20 times safer than an airplane
250 times safer than other conventional railways.
700 times safer than travel by road
Collision is impossible because only sections of the track are activated as needed. The vehicles always travel in synchronization and at the same speed, further reducing the chances of a crash.

Operation Costs

Virtually no wear. Main cause of mechanical wear is friction. Magnetic Levitation requires no contact, and hence no friction.
Components normally subjected to mechanical wear are on the whole replaced by electronic components which do not suffer any wear
Specific energy consumption is less than all other comparable means of transportation.
