Maglev Trains: the Future of Transportation? Maglev Trains: The Future of Transportation? By Jason Moore What are Maglev Trains? Maglev trains ride or float on a cushion of air. Maglev trains do not use an engine to move like traditional trains. They use a technology called magnetic levitation. (The name maglev is a combination of the words magnetic and levitation.) Electromagnets are placed on the train and on the guideway, or track. When electricity flows through the electromagnets, they act like magnets. One set of the magnets repel. That means they push away from one another. This reaction between the magnets creates a magnetic field. The field lifts the train off of the track. This lets air flow between the train and the guideway. The trains never touch the Magnets levitate when they repel. The track; they hover just above the track. A second set of magnets word levitation means to rise up in the move the 'floating train' ahead. The trains move quickly because air. they aren’t slowed down by friction between wheels and track. Where was the first maglev train? China was the first country to run a maglev train. This commercial train opened on December 31, 2002. The train takes passengers to and from the Pudong Airport to the city center 19 miles away. The trip takes about eight minutes. That’s because the train can travel up to 267 miles per hour! A trip through the city traffic would take much, much longer! What are the advantages? Maglev trains do not have as many parts as traditional trains. This means there are less breakdowns. These trains have no wheels running along metal tracks, so they are very quiet. They are friendly to the environment. There is no engine to create pollution. The trains are weatherproof too. Snow, cold weather, and rain don’t affect how they run. This means there is Maglev Train less disruption to schedules. 1 © Copyright by Write Score LLC Maglev trains are designed to glide through the air. The front is curved so that the air slides over the train as it moves. This helps the train to move faster and reduces friction with the air. Maglev trains can move at speeds up to 300 miles per hour. That is twice as fast as Amtrak’s fastest commuter train. What are the disadvantages? The biggest downside to maglev trains is the cost. These trains can’t run on the tracks that already exist in many countries. This means that the train tracks that already exist would have to be changed to work with maglev trains. Another idea would be to build all new tracks. Both ideas are very expensive. 2 © Copyright by Write Score LLC Name_________________________________ Use the passage Maglev Trains: The Future of Transportation? to answer these questions.

  • Modeling and Simulation of Shanghai MAGLEV Train Transrapid with Random Track Irregularities
    Modeling and Simulation of Shanghai MAGLEV Train Transrapid with Random Track Irregularities Prof. Shu Guangwei M.Sc. Prof. Dr.-Ing. Reinhold Meisinger Prof. Shen Gang Ph.D. Shanghai Institute of Technology, Shanghai, P.R. China Nuremberg University of Applied Sciences, Nuremberg, Germany Tongji University, Shanghai, P.R. China Abstract The MAGLEV Transrapid is a kind of new type high speed train in the world which is levitated and gui- ded over the track using electro magnetic forces. Because the electro magnets are unstable, they ha- ve to be controlled. Since 2002 the worldwide first commercial use of such a high speed train based on German technology is running successfully in Shanghai Pudong Airport, P.R.China. In this paper modeling of the high speed MAGLEV train Transrapid is discussed, which considered the whole mechanical system of one vehicle with optimized suspension parameters and all controlled electro magnet pairs in vertical and lateral directions. The dynamical simulation code is generated with MATLAB/SIMILINK. For the design of the control system, the optimal Linear Quadratic Control for minimum control energy is used for each single electro magnet. The simulation results are presen- ted with the given vertical and lateral random track irregularities. The research work was carried out together with Prof. Shen Gang, Ph.D. during the time Prof. Dr. Meisinger was visiting professor in Shanghai 2006 and Prof. Shu Guangwei, M.Sc. was visiting profes- sor in Nuremberg 2007.

Department of Energy |January 2021 [ This page is intentionally left blank] Effect of Hyperloop Technologies on Electric Grid and Transportation Energy | Page i Department of Energy |January 2021 Executive Summary Hyperloop technology, initially proposed in 2013 as an innovative means for intermediate- range or intercity travel, is now being developed by several companies. Proponents point to potential benefits for both passenger travel and freight transport, including time-savings, convenience, quality of service and, in some cases, increased energy efficiency. Because the system is powered by electricity, its interface with the grid may require strategies that include energy storage. The added infrastructure, in some cases, may present opportunities for grid- wide system benefits from integrating hyperloop systems with variable energy resources.

Magnetic-suspension systems, which have high nonlinearity and open-loop instability, are the core components of maglev vehicles. The high-performance control of maglev vehicles has been the focus of numerous studies. Encountering challenges in the levitation control of maglev vehicles in the form of uncertain time delays and disturbances is unavoidable. To cope with these problems, this study presents the design of an adaptive robust controller based on the Riccati method and sliding-mode technology, simultaneously taking into account the influence of time delays and disturbances. The asymptotic stability of the closed-loop system with the proposed control law is proved by the Lyapunov method. Control performances of the proposed controller are shown in the simulation results. Together with the consistently stabilizing outputs, the presented control approach can handle time delays and disturbances well. Finally, experiments were also implemented to examine its practical control performance of the robust levitation-control law.

  • The Workings of Maglev: a New Way to Travel
    THE WORKINGS OF MAGLEV: A NEW WAY TO TRAVEL Scott Dona Amarjit Singh Research Report UHM/CE/2017-01 April 2017 The Workings of Maglev: A New Way to Travel Page Left Blank ii Scott Dona and Amarjit Singh EXECUTIVE SUMMARY Maglev is a relatively new form of transportation and the term is derived from magnetic levitation. This report describes what maglev is, how it works, and will prove that maglev can be successfully constructed and provide many fully operational advantages. The different types of maglev technology were analyzed. Several case studies were examined to understand the different maglev projects whether operational, still in construction, or proposed. This report presents a plan to construct a maglev network using Maglev 2000 vehicles in the United States. A maglev system provides energy, environmental, economic, and quality of life benefits. An energy and cost analysis was performed to determine whether maglev provides value worth pursuing. Maglev has both a lower energy requirement and lower energy costs than other modes of transportation. Maglev trains have about one-third of the energy requirement and about one- third of energy cost of Amtrak trains. Compared to other maglev projects, the U.S. Maglev Network would be cheaper by a weighted average construction cost of $36 million per mile. Maglev could also be applied to convert the Honolulu Rail project in Hawaii from an elevated steel wheel on steel rail system into a maglev system. Due to the many benefits that Maglev offers and the proof that maglev can be implemented successfully, maglev could be the future of transportation not just in the United States but in the world.

  • Solar-Powered Vactrain – a Preliminary Analysis
    SOLAR-POWERED VACTRAIN – A PRELIMINARY ANALYSIS Sundar Narayan Lambton College ABSTRACT This paper analyzes a high-speed electric train running inside an evacuated tunnel that is powered by solar panels mounted above the tunnel that continuously produce 137 kW of average power per km of track. This train will be totally weather-proof and consume much less power than today’s high speed trains, so that surplus solar electricity from the solar panels can be profitably sold to the grid. A preliminary economic analysis indicates that this 500 km/h solar-powered vactrain can be profitable at a ticket price of 0.29 to 0.40 U.S dollars per km per passenger so that it will be cheaper than air travel. INTRODUCTION High Speed Trains such as the Japanese Shinkansen bullet train and the French Train a Grande Vitesse (TGV) are technological success stories as well as economically profitable with an excellent safety record [Gow, 2008]. These electric trains routinely travel at speeds of over 300 km/h (180 mph) though the TGV holds the world record by reaching a top speed of 574.8 km/h in April 2007. However, such record- breaking runs require special track preparation and overhead electric catenary tensioning and are not practically achievable on a day-to-day basis. Trials with the Fastech 360 bullet trains show that a peak speed of 360 km/h may not be achievable under Japanese conditions because of noise concerns, excessive overhead wire wear and braking distances. In France too, there have been a few protests against the noise from the TGV [Davey ,2001].

This article draws attention to the similarities of the engineering problems when designing the passenger compartment of the vacuum vehicle equipped with the life support system and the aircraft. It allows using the aviation system design experience for development of a vacuum transport system. As the most similar prototype, the Japanese JR-Maglev high-speed system is considered. The assumption is made that the adaptation of JR-Maglev traction levitation system to the aviation technologies can become one of the directions to design a vacuum magnetic levitation transport system. For justification of this assumption, the layout diagram of the vacuum transport system adapted to the aviation fuselage is provided. The assessment of the energy consumption for the route is given. The vacuum transport system is compared with the airbus A320 in terms of specific energy consumption.
