Maglev
Maglev (derived from '' magnetic levitation''), is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Such trains rise approximately off the track. There are both high speed, intercity maglev systems (over ), and low speed, urban maglev systems ( to ) being built and under construction and development. With maglev technology, the train travels along a guideway of electromagnets which control the train's stability and speed. While the propulsion and levitation require no moving parts, the bogies can move in relation to the main body of the vehicle and some technologies require support by retractable wheels at low speeds under . This compares with electric multiple units that may have several dozen parts per bogie. Maglev trains can therefore in some cases be quieter and smoother than conventional trains and have ...

Transrapid Shanghai Maglev Train Ride
Transrapid is a German-developed high-speed monorail train using magnetic levitation. Planning for the Transrapid system started in 1969 with a test facility for the system in Emsland, Germany completed in 1987. In 1991, technical readiness for application was approved by the Deutsche Bundesbahn in cooperation with renowned universities. The last version, the Transrapid 09, is designed for a cruising speed of and allows acceleration and deceleration of approximately . In 2002, the first commercial implementation was completed – the Shanghai Maglev Train, which connects the city of Shanghai's rapid transit network to Shanghai Pudong International Airport. The Transrapid system has not yet been deployed on a long-distance intercity line. The system is developed and marketed by Transrapid International, a joint venture of Siemens and ThyssenKrupp. In 2011, the Emsland test track closed down when its operating license expired. In early 2012, demolition and reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AirRail Link
The Air-Rail Link is a people mover linking Birmingham Airport with Birmingham International railway station and the National Exhibition Centre in England. The current system, originally known as SkyRail, replaced the earlier Birmingham Maglev system in 2003. The current system is a fully automated cable-hauled system that opened in 2003 and has a length of . It takes passengers between the high-level railway station concourse and the airport terminal buildings. It is free to use, and handles three million passengers per year. The Birmingham Maglev was opened in 1984 and was the first commercial Maglev transport system in the world. It operated up until 1995. The system was fully automated and used an elevated concrete guideway, much of which has been reused for the current Air-Rail Link system. Maglev Initial feasibility studies for a link from the airport to the railway station and exhibition centre were started in 1979 by the owners of the airport at that time, West Mid ...

Magnetic Levitation
Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. The two primary issues involved in magnetic levitation are ''lifting forces'': providing an upward force sufficient to counteract gravity, and ''stability'': ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized. Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes. Lift Magnetic materials and systems are able to attract or repel each other with a force dependent on the magnetic field and the area of the magnets. For example, the simplest example of lift would be a simple dipole magnet positioned in the magnetic fields of another dipole magnet, oriented with like poles facing each other, so that the force between m ...

Linear Motor
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque ( rotation), it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop. A typical mode of operation is as a Lorentz-type actuator, in which the applied force is linearly proportional to the current and the magnetic field (\vec F = I \vec L \times \vec B). Linear motors are by far most commonly found in high accuracy engineering applications. It is a thriving field of applied research with dedicated scientific conferences and engineering text books. Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pudong
Pudong is a district of Shanghai located east of the Huangpu, the river which flows through central Shanghai. The name ''Pudong'' was originally applied to the Huangpu's east bank, directly across from the west bank or Puxi, the historic city center. It now refers to the broader Pudong New Area, a state-level new area which extends all the way to the East China Sea. The traditional area of Pudong is now home to the Lujiazui Finance and Trade Zone and the Shanghai Stock Exchange and many of Shanghai's best-known buildings, such as the Oriental Pearl Tower, the Jin Mao Tower, the Shanghai World Financial Center, and the Shanghai Tower. These modern skyscrapers directly face Puxi's historic Bund, a remnant of former foreign concessions in China. The rest of the new area includes the Port of Shanghai, the Shanghai Expo and Century Park, Zhangjiang Hi-Tech Park, Shanghai Pudong International Airport, the Jiuduansha Wetland Nature Reserve, Nanhui New City, and the Sh ...

Train
In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the late 180 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracked Hovercraft
Tracked Hovercraft was an experimental high speed train developed in the United Kingdom during the 1960s. It combined two British inventions, the hovercraft and linear induction motor, in an effort to produce a train system that would provide inter-city service with lowered capital costs compared to other high-speed solutions. Substantially similar to the French Aérotrain and other hovertrain systems of the 1960s, Tracked Hovercraft suffered a similar fate to these projects when it was cancelled as a part of wide budget cuts in 1973. History Genesis at Hovercraft Development It was noticed early on in the development of the hovercraft that the energy needed to lift a vehicle was directly related to the smoothness of the surface on which it travelled. This was not entirely surprising; the air trapped under the hovercraft will remain there except where it leaks out where the lifting surface contacts the ground — if this interface is smooth, the amount of leaked air will ...

Eric Laithwaite
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of Maglev" for his development of the linear induction motor and maglev rail system. Biography Eric Roberts Laithwaite was born in Atherton, Lancashire, on 14 June 1921, raised in the Fylde, Lancashire and educated at Kirkham Grammar School. He joined the Royal Air Force in 1941. Through his service in World War II, he rose to the rank of Flying Officer, becoming a test engineer for autopilot technology at the Royal Aircraft Establishment in Farnborough. On demobilization in 1946, he attended the University of Manchester to study electrical engineering. His work on the Manchester Mark I computer earned him his master's degree. His subsequent doctoral work started his interest in linear induction motors. He derived an equation for "goodness" which parametrically describes the efficiency of a motor in general terms, and showed that it tended to imply th ...
