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 t ...

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 recon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mag ...

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 Shang ...

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 Mi ...

People Mover
A people mover or automated people mover (APM) is a type of small scale automated guideway transit system. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks. The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964. The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or WEDway PeopleMover, was an attraction that was originally presented by Goodyear Tire and Rubber Company and that opened at Disneyland in 1967. Now, however, the term "people mover" is generic, and may use technologies such as monorail, rail tracks or maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction. Generally speaking, larger APMs ar ...

Derby
Derby ( ) is a city and unitary authority area in Derbyshire, England. It lies on the banks of the River Derwent in the south of Derbyshire, which is in the East Midlands Region. It was traditionally the county town of Derbyshire. Derby gained city status in 1977, the population size has increased by 5.1%, from around 248,800 in 2011 to 261,400 in 2021. Derby was settled by Romans, who established the town of Derventio, later captured by the Anglo-Saxons, and later still by the Vikings, who made their town of one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era. Home to Lombe's Mill, an early British factory, Derby has a claim to be one of the birthplaces of the Industrial Revolution. It contains the southern part of the Derwent Valley Mills World Heritage Site. With the arrival of the railways in the 19th century, Derby became a centre of the British rail industry. Derby is a centre for advanced transport manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Research Division
The British Rail Research Division was established in 1964 directly under the control of the British Railways Board, moving into purpose-built premises at the Railway Technical Centre in Derby. The intention was to improve railway reliability and efficiency, while reducing costs and improving revenue. In so doing it became recognised as a centre of excellence and, in time, was providing consultancy to other railways around the world. While it became famous for the Advanced Passenger Train (APT), its activities extended into every area of railway operation. The theoretical rigour of its approach to railway engineering superseded the ad hoc methods that had prevailed previously. Work The Research Division brought together personnel and expertise from all over the country, including the LMS Scientific Research Laboratory. Its remit was not simply the improvement of existing equipment, or the solution of existing problems, but fundamental research from first principles, into railwa ...

Magnetic River
Magnetic river is an electrodynamic magnetic levitation (maglev) system designed by Fredrick Eastham and Eric Laithwaite in 1974. It consists of a thin conductive plate on an AC linear induction motor. Due to the transverse flux and the geometry, this gives it lift, stability and propulsion as well as being relatively efficient. The name refers to the action that provides stability along the longitudinal axis, which acts similar to the flow of water in a river. Linear motors A linear induction motor (LIM) is essentially a conventional induction motor with its primary "unwound" and laid out flat. The rotor, normally consisting of a series of conductors wound onto a form of some sort, is replaced by a sheet of magnetically susceptible metal. Due to its good conductance to weight ratio, aluminium is almost always used for this "stator plate". When the primaries are fed current, they induce a magnetic field in the stator plate, which generates forces away from the plate and along it. ...

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 b ...

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 appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
