Outline

What maglev train:    The MagLev use magnetic trains

suspended in the tracks above. Maglev trains are often referred to as the MagLev, Magnetically Levitated train shorthand.

Inventor:  In 1922, the German Hermann Kemper

electromagnetic floating principle, in 1934 the world‘s first one on the maglev technology patent.

The maglev introuduction

Two types of maglev in the world: Japan represented superconductivity

maglev. Germany,represented by the often

conductive magnetic levitation.

The type and composition of the maglev train

German Transrapid 07Japan ML100

Maglev technology is divided into tracks, vehicles, traction, run control four systems, 16 core technology.

Movie.1

The principle of the maglev train The maglev train propulsion system with

motor propulsion, equivalent to the portion of the motor housing fixed on the ground, and the rotary motor magnet mounted on the vehicle body electromagnet instead.The opposite wall with both side of the train, equipped with the equivalent of general motor field coil coil, pass on the current, it will become an electromagnet.

Levitation principle Control the the electromagnet magnetic force can be stationary suspension

Speed induction induced suspension capability, the speed of the car is about 70 km above suspension

Suspended position Attract home on the track

Track side suction push

Levitation gap 1.5cm 30cm

Top speed 430 km/hr 550 km/hr

Climbing degree 10 % 4 %

Power station is set UHP partition settings Double circuit EHV partition settings

Japan MLX01-2 superconducting solenoid bogie

Research stage maximum speeds of up to 450km / h

China officially began trial operation speeds of up to 430km / h

Japanese manned maglev train test speeds of up to 411km / h

Top speed

Movie.2

Technology Advantage Disadvantage EMS Train inside and outside of the

magnetic field is low compared to the electric power suspension. Has proved technically up to a very high speed (over 500 km / h).

Due to the inherent instability of the system need to be constantly revised and external systems, vibration may cause a problem in the system.

EDS Built magnet is substantially used in the train and the track, technically up to a very high speed (581 km / h) and a high load capacity.

The inducibility of the tracks will limit the maximum speed of the train, the train must have a rotation running at low speed.

Indutrack Failsafe suspension system without power as to activate magnet; at low speed (approximately 5 km / h) to generate sufficient magnetic field of the maglev train suspended

When the train stop, still needs a period of continued movement of the wheel or track.
