Available in PDF, EPUB and Kindle. Book excerpt: Key Features:Intimate relationship between superconductivity and magnetic fields to achieve high speed highlighted. Dynamics between wheel, rail and track explained. Dynamics braking and its significance explained. Extensive coverage of magnetic levitated super fast trains will benefit engineering students and practicing engineers. Examples will electronic spread sheet type of calculation for loads, stresses, dynamic response and stability.About the Book:Magnetically levitated bullet trains are the most interesting development of the new millennium, recording travel at unheard of speed levels. The train levitates above the tracks using electromagnets to create a nearly friction less ride, without making contact with the ground. Moving more smoothly and quietly than wheeled mass transit systems, the power needed for levitation is mostly to overcome aerodynamic drag.A confluence of superconductivity and magnetic technologies has produced this spectacular event. Superconducting magnets do not dissipate energy to maintain the magnetic field. A superconductor levitated above a permanent magnet remains in stable equilibrium. Resistance to flow of electric current in the conductor vanishes, so the magnetically levitated coaches operate without external energy. At the same time, however, initial cost of development and installation is prohibitive.This book provides tools for design and operation of a massive locomotive pulling a heavily loaded train through mountainous regions. Extracting maximum power, emit acceptable levels of exhaust pollutants, accelerate smoothly and safely come to stop are of significance. Passenger coaches must not pitch and roll when subjected to strong cross winds, and while negotiating sharp curves.Safeguards from dynamic operating conditions are required to avoid failures from: Train derailment due to deformed wheel and deficiencies in track pathway ? Establish dynamic loads from interaction between wheel, rail and track ballast ? Design compliant mount between vehicle body and bogie wheel assembly ? Rolling contact stress and thermal fatigue in wheel from abrupt brake application.

Book excerpt: This book provides a comprehensive overview of magnetic levitation (Maglev) technologies, from fundamental principles through to the state-of-the-art, and describes applications both realised and under development. It includes a history of Maglev science and technology showing the various milestones in its advancement. The core concepts, operating principles and main challenges of Maglev applications attempted across various fields are introduced and discussed. The principle difficulties encountered when applying Maglev technology to different systems, namely air gap control and stabilization, are addressed in detail. The book describes how major advancements in linear motor and magnet technologies have enabled the development of the linear-motor-powered Maglev train, which has a high speed advantage over conventional wheeled trains and has the potential to reach speed levels achieved by aircraft. However, many expect that Maglev technology to be a green technology that is applied not only in rail transportation, but also in diverse other fields; to ensure clean transfer in LCD manufacturing, in ropeless high speed elevators, small capacity rail transportation, space vehicle launchers, missile testers, energy storage, and so on. These potential applications and their unique challenges and proposed technological solutions are introduced and discussed in depth.

Available in PDF, EPUB and Kindle. Book excerpt: Linear motion is richly present in various industries, from direct electric propulsion in urban and interurban people movers on wheels or on magnetic “cushions” (MAGLEVs) to indoor transport of goods (conveyors, etc.), through plunger solenoids (to open hotel doors and as electromagnetic power switches), to compressor drives by linear oscillatory permanent magnet (PM) motors, smart phones integrated microphone and loudspeakers, and controlled vehicles’ suspension, etc. Besides the traditional rotary motor drives with mechanical transmissions, which mean friction limitations (weather dependent) in traction (heavy vehicles), more losses, positioning errors (backlash) in the process, and higher maintenance costs to handle them, linear motion in industry by direct electromagnetic forces is free of friction limitations for traction, free of mechanical transmission, and thus more efficient, with less maintenance cost and fewer positioning errors (backlash). This explains why they are used in so many applications already since the dramatic advancement of power electronics and digital control in the last four decades. Modeling, performance, design, control, and testing of linear electric machines (LEMs) show notable differences with respect to rotary electric motor drives, which warrant a dedicated treatment of these aspects. The Second Edition (First Edition: 2013) concentrates on the above technical aspects of various types of LEMs in close relationship with specific applications via numerical examples of modeling, design, control, and testing, with ample representative results from literature, industry and some of the author’s contributions, such as: Technical field and circuit modeling of linear induction motors in flat configurations for low and high speeds (with and without dynamic end effects) and in tubular configurations short travel design, control and testing Linear synchronous motor (LSM) drives in dc-excited, homopolar, reluctance and superconducting excitation configurations for urban and interurban high-speed vehicles propulsion and integrated propulsion and levitation (in MAGLEVs) modeling, design and control with full-scale numerical examples, with emphasis on lower KWh/passenger/Km at high speeds Flat and tubular linear permanent magnet (PM) synchronous motors (L-PMSMs), mainly destined to industrial indoor transport for automation at high efficiency in clean rooms Linear “flux-modulation” motors— new breed, suitable for very low-speed applications due to higher thrust density Plunger solenoids in various applications including new valve PM actuators with millisecond response time Linear resonant PM oscillatory motors design, control and testing mainly destined to compressors for higher efficiency in compact drives Attraction and repulsive force suspension (levitation) systems for MAGLEVs Active and passive guideway MAGLEVs in urban and superhigh-speed interurban transport at lower Kwh per passenger/km (in lighter vehicles without wheels) The numerous numerical design and control examples (with practical specifications) throughout the 23 chapters of the book allow the reader deep and fast access to a practical but thorough unitary (good for comparisons) methodology in designing and controlling LEMs for various applications.

This book was released on 2008-09-22 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2008 in the subject Engineering - Industrial Engineering and Management, grade: 1,3, Vrije University Brussel (Solvay Business School), course: Advanced Technology, language: English, abstract: The magnetic levitation train analysed in this study was developed in Germany by the Transrapid International GmbH & Co. KG, a joint venture by Siemens AG and ThyssenKrupp AG, as a means for high speed transportation. First prototypes were presented to the public as early as 1969 and 1979, yet, the first public high-speed maglev track was opened only four years ago in Shanghai, China. Despite the fact that businesspeople like engineers from all sorts of backgrounds speak very highly of the technology, the Shanghai track remains the only commercially operated one thus far.1 Purpose of this paper is to analyse the potential of the maglev train, to assess its strengths and weaknesses, and to spot opportunities as well as threats to the application of this state-of-the-art - or perhaps ahead-of-its-time - technology.
