Extractions: Magnetic Levitation Vehicles Introduction As we move toward the twenty first century, an analysis of our transportation needs indicates that the systems we have in place today may not be capable of supporting our transportation needs for the future. Because of the growing need for quicker and more efficient methods for moving people and goods, researchers have turned to a new technique, one using electromagnetic rails and trains. This rail system is referred to as magnetic levitation , or maglev . Maglev is a generic term for any transportation system in which vehicles are suspended and guided by magnetic forces. Instead of engines, maglev vehicles use electromagnetism to levitate (raise) and propel the vehicle. Alternating current creates a magnetic field that pushes and pulls the vehicle and keeps it above the support structure, called a guide way There are two basic types of maglev - electromagnetic suspension (EMS) and electrodynamic suspension (EDS) EMS depends on attractive force . Electromagnets on the vehicle are drawn toward a pair of steel rails. Most of the vehicle rides above the rails but the magnets wrap beneath the rail. As the magnets pull the vehicle upward, their current is electromagnetically regulated to maintain a constant gap between the rails and the vehicle.

Extractions: Colorado Department of Transportation - Magnetic Levitation Research PUBLIC INFORMATION PACKAGE The Colorado Department of Transportation has entered into a "Memorandum of Understanding" to conduct research and development under the federal Urban Magnetic Levitation program. The other parties to this agreement are: Colorado Intermountain Fixed Guideway Authority (CIFGA) Sandia National Laboratories (SNL) MagLev Transit Group (MTG) In 1999, CIFGA and SNL were identified by the US Congress to each receive $1.75M to study and develop magnetic levitation technology for use in urban transit. MTG was selected, based on competitive proposals, by the Federal Transit Administration (FTA) to receive $742,000 to conduct magnetic levitation research. CDOT is receiving these $4,242,000 in grant funds through a cooperative agreement with the FTA and is contracting with the three participants to conduct the research and development. The state funds being used for appropriately related analysis in the ongoing I-70 west Programmatic Environmental Impact Study (I-70 PEIS) provide the required match. The I-70 PEIS study is expected to be result in a Record of Decision in 2004. CDOT is working in partnership with the other groups involved to provide accurate and complete information regarding possible advanced technology alternatives for the I-70 West Corridor. Information about this system, along with information on other fixed guideway systems, and highway, rubber-tire transit (bus), and other transportation alternatives, will be used to determine a preferred alternative for a long-term plan for the corridor.

http://www.desc.med.vu.nl/Magnet_us.htm

Extractions: Magnetic levitation Every element (in the periodic system) is magnetic. However, there are three main levels or domains of magnetism. The smallest effect is know as diamagnetism and is a property of elements like antimony, bismuth, copper, carbon but also phosphorus and hydrogen. Paramagnetism has an intermediate value, about two orders of magnitude higher than diamagnetism. Paramagnetism is seen in e.g. aluminum, zinc, liquid oxygen but also in glass and rubber. The largest magnetic effect is known as ferromagnetism. This is, in our daily life, the most common form of magnetism. The only elements with ferromagnetic properties are iron, cobalt, and nickel. Ferromagnetism is about 10 times larger compared to diamagnetism. Ferro and paramagnetic elements may easily be levitated in low gradient magnetic fields. This system is used in various commercial products. To elevate diamagnetic materials, however, much higher field strengths and field gradients are necessary. In such a high power magnet organic materials or even living biological samples may be elevated, thereby counteracting the force of gravity.

Extractions: BACKGROUND The Subcommittee will conduct a hearing to examine magnetic levitation transportation issues. Magnetic levitation (maglev) is an advanced technology in which magnetic forces lift, propel, and guide a vehicle over a guideway. Utilizing state-of-the-art electric power and control systems, this configuration eliminates contact between vehicle and guideway. Maglev systems, although not yet in revenue service, have been demonstrated to operate at speeds around 300 miles per hour (mph). High-speed passenger trains such as the European TGV and ICE systems, using flanged wheels and steel rails, have also reached speeds approaching the 300 mph level on dedicated rights-of-way. Because of its high acceleration and cruising speed, maglev offers competitive trip-time savings to auto and aviation modes in the 40 to 600-mile travel markets. By comparison, current U.S. passenger trains such as the Amtrak Metroliners operate at up to 125 mph on parts of the Northeast Corridor. The new Acela high-speed trains used by Amtrak are capable of 150 mph, but in most areas except the newly electrified New Haven-Boston segment of the Northeast Corridor, they are limited to about 130 mph by the infrastructure. The Maglev Deployment Program in TEA 21 In 1998 Congress passed the "Transportation Equity Act for the 21st Century" (TEA 21), which created a National Magnetic Levitation Transportation Technology Deployment Program. The program is to demonstrate high-speed maglev technology in commercial service through a project of about 40 miles in length.

Extractions: Fill out our online form Email Us Report a dead link Magnetic Levitation (MAGLEV) Magnetic levitation or Maglev refers to a super speed train levitated above a guideway by magnets. Using electricity, the magnets also propel the train on a cushion of air at speeds up to 300 miles per hour. Recently Congress approved TEA 21 - the largest transportation bill in history - that included $1.1 billion for Maglev deployment. Of the $1.1 billion for Maglev, the first $60 million has been spent on studies of the technology in seven corridors nationally. Based on the results of the studies, the US Department of Transportation will select one project to receive $950 million in federal construction funds. The Maglev Maryland project has moved into high gear. Phyllis Wilkins, Executive Director of Maglev Maryland for Baltimore Development Corporation (BDC), has been coordinating the regional effort since its inception working with the Departments of Transportation for Maryland and Washington, DC. Maryland Mass Transit Administration (MTA) is managing the study being conducted by a consulting team. In 1992, Maryland received a grant to perform the first Maglev feasibility study through the ISTEA transportation bill. The feasibility study released in 1994 has been widely recognized as one of the finest in the country and is the foundation for the current study efforts.

Extractions: Using Piezoelectric Actuator Keywords: Magnetic Levitation, Piezoelectric Actuator, Permanent Magnet Abstract A type of magnetic levitation system with permanent magnet motion control has been already proposed. The feature is to control attractive force of permanent magnet using actuator. Based on this principle, a 1 DOF hanging type magnetic levitation system has been developed. The levitated object hangs from the upper ferromagnetic ceiling. This system had problem that the levitated object swings. Next step is development of a 3 DOF magnetic levitation system. A 3 DOF magnetic levitation system that can control the DOFs of the rotation about horizontal axes is developed. This paper describes the success of a 3 DOF magnetic levitation system using permanent magnets and piezoelectric actuators. INTRODUCTION The need for a very clean environment is increasing in such areas as semiconductor processing and biotechnological experiments. During conveyance and handling of an object, dust and particles are generated from contact points. The conveyance vehicles used in these areas must eliminate contamination. Thus mechanical contacts are the prime origins of dust and particle generation. A non-contact conveyance mechanism is good solution for clean environment applications. Most of magnetic levitation system is a type of system which controls attractive force of electromagnet by varying electric current. Also, a type of magnetic levitation system which controls attractive force of permanent magnet by varying air gap length has been already proposed

http://www.sri.com/news/releases/05-30-00.html

Extractions: MENLO PARK, Calif. (May 23, 2000) - Silicon Valley-based SRI International received both "Best of Show" awards at the Sensors and Motion Control Expositions (May 9 to 11, 2000) for its passive diamagnetic levitation system. SRI's entry won against dozens of other entries for top honors at the events, reaffirming the organization's role as a leading technology innovator. The passive diamagnetic levitation system makes non-contact suspension and transportation possible without the use of electromagnets, control systems or power. The Sensors and Motion Control Expositions are the only events dedicated to the utilization of sensor and motion technologies and their related applications. This year's expositions, held concurrently at the Anaheim Convention Center in Anaheim, California, and sponsored by Sensors Magazine and the American Institute of Motion Engineers respectively, brought together over 325 companies displaying a full range of related technologies. Diamagnetism is a property of some materials such as graphite that causes them to levitate in a stable manner in a magnetic field without power. SRI has studied this phenomenon and has recently developed passive diamagnetic levitation system technologies for several useful devices. Passive diamagnetic levitation system technology has a broad range of applications, from precise seismic sensors to frictionless micromotors, and is particularly valuable for use in clean room transport to eliminate particulate contaminants.

Extractions: If you've been to an airport lately, you've probably noticed that air travel is becoming more and more congested. Despite frequent delays, airplanes still provide the fastest way to travel hundreds or thousands of miles. Passenger air travel revolutionized the transportation industry in the last century, letting people traverse great distances in a matter of hours instead of days or weeks. The only alternatives to airplanes feet, cars, buses, boats and conventional trains are just too slow for today's fast-paced society. However, there is a new form of transportation on the horizon that will revolutionize transportation of the 21st century the way airplanes did in the 20th century.

Extractions: Previous Story ... Related Stories Next Story Source: Carnegie Mellon University Date: The device is unique because it enables people to not only touch these objects, but to reach in and manipulate them in three dimensions as well. The new system also eliminates the bulky links, cables and mechanisms of current haptic interfaces in favor of a single, lightweight moving part, which floats on magnetic fields. The system has a bowl-shaped floating element containing six levitation coils surrounded by strong, permanent magnets. A protruding handle attached to the bowl is grasped by the computer user, enabling interaction with solid, three-dimensional models graphically depicted on the computer screen. The system is housed in a desktop-high cabinet. It has taken Hollis and his Ph.D. student, Peter Berkelman, five years to develop the haptic interface. They believe that future applications of the technology will be in computer-augmented design, medical training, entertainment, flight simulation and the interactive control of remote robots.
