SCMaglev
The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation (maglev) railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute. The SCMaglev uses an electrodynamic suspension (EDS) system for levitation, guidance, and propulsion. In development since the 1960s, the SCMaglev system will be used in the Chūō Shinkansen rail line between Tokyo and Nagoya, Japan. The line, currently under construction, is scheduled to open in 2034 (after delays pushing back its original opening date of 2027.) JR Central is also seeking to sell or license the technology to foreign rail companies. The L0 Series, a prototype vehicle based on SCMaglev technology, holds the record for fastest crewed rail vehicle with a record speed of . Technology The SCMaglev system uses an electrodynamic suspension (EDS) system. The train's bogies have superconducting magnets installed, and the guideways contain two sets o ...

Maglev
Maglev (derived from '' magnetic levitation'') is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance. Compared to conventional railways, maglev trains have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds. Maglev trains have set several speed records. The train speed record of was set by the experimental Japanese L0 Series maglev in 2015. From 2002 until 2021, the record for the highest operational speed of a passenger train of was held by the Shanghai maglev train, which uses German Transrapid technology. The service connects Shanghai Pudong International Airport and the outskirts of central Pudong, Shanghai. At its historical top speed, it covered the distance of in just over 8minutes. ...

Nagoya
is the largest city in the Chūbu region of Japan. It is the list of cities in Japan, fourth-most populous city in Japan, with a population of 2.3million in 2020, and the principal city of the Chūkyō metropolitan area, which is the List of metropolitan areas in Japan, third-most populous metropolitan area in Japan with a population of 10.11million. Located on the Pacific Ocean, Pacific coast in central Honshu, it is the capital and most populous city of Aichi Prefecture, with the Port of Nagoya being Japan's largest seaport. In 1610, the warlord Tokugawa Ieyasu, a retainer of Oda Nobunaga, moved the capital of Owari Province from Kiyosu to Nagoya. This period saw the renovation of Nagoya Castle. The arrival of the 20th century brought a convergence of economic factors that fueled rapid growth in Nagoya during the Meiji Restoration, and it became a major industrial hub for Japan. The traditional manufactures of timepieces, bicycles, and sewing machines were followed by the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrodynamic Suspension
Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart. These time-varying magnetic fields can be caused by relative motion between two objects. In many cases, one magnetic field is a permanent field, such as a permanent magnet or a superconducting magnet, and the other magnetic field is induced from the changes of the field that occur as the magnet moves relative to a conductor in the other object. Electrodynamic suspension can also occur when an electromagnet driven by an AC electrical source produces the changing magnetic field, in some cases, a linear induction motor generates the field. EDS is used for maglev trains, such as the Japanese SCMaglev. It is also used for some classes of magnetically levitated bearings. Types Many examples of this have been used over th ...

Linear Motor
A linear motor is an electric motor that has had its stator and rotor (electric), 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. Linear motors are used by the millions in high accuracy CNC machining and in industrial robots. In 2024 this market was USD 1.8 billion. A typical mode of operation is as a Lorentz force, Lorentz-type actuator, in which the applied force is linear equation, linearly proportional to the electric current, current and the magnetic field (\vec F = I \vec L \times \vec B). 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 ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ground Effect Train
A ground-effect train is a conceptualized alternative to a magnetic levitation train, magnetic levitation (maglev) train. In both cases the objective is to prevent the vehicle from making contact with the ground. Whereas a maglev train accomplishes this through the use of magnetism, a ground-effect vehicle, ground-effect train uses an air cushion; either in the manner of a hovercraft (as in hovertrains) or using the wing–in–ground-effect design. Details The advantages of a ground-effect train over a maglev are lower cost due to simpler construction. Disadvantages include either constant input of energy to keep the train hovering (in the case of hovercraft-like vehicles) or the necessity to keep the vehicle moving for it to remain off the ground (in the case of wing–in–ground-effect vehicles). Furthermore, these vehicles may be very drastically affected by wind, air turbulence, and weather. Whereas the magnetic levitation train can be built to operate in a vacuum to minimise ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...
