Safety of High Speed Magnetic Levitation Transportation Systems: Final Report on Magnetic Field Testing of TR-07 Maglev Vehicle, Volume I - Analysis
The safety of various magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is of direct concern to the Federal Railroad Administration (FRA). The characterization of electric and magnetic fields (EMF) emissions, both steady (dc) and...
Recommendations for Acoustical Test Facility for Maglev Research
Noise from high speed operations of a maglev system is a source of concern. The German and Japanese prototype maglev systems generate high noise levels at very high speeds. Without mitigation, a maglev system may encounter public opposition if introduced to the existing transportation system in the...Preliminary Design Guidelines for Noise Control on High Speed Maglev Trains
This report builds on the first two reports of this series and provides preliminary guidelines on the prediction, assessment and mitigation of noise from maglev systems. The first report identifies noise sources from high speed maglev operations and recommends further research to help determine the...Power Transfer to High Speed Vehicles
This final report summarizes work performed in the assessment and analysis of power transfer techniques to high speed vehicles. The objectives of this research were to determine the optimum power transfer technique for two power levels at high speed and to prepare a preliminary design of the...Novel Cryogen-free Actively Shielded Superconducting Magnets for Maglev Vehicles
This report presents the results of a research effort into the design of a shielded superconducting magnet system for a maglev vehicle. The magnet design is based on a novel cryogen-free technology which allows operation without the use of any cryogenic fluids. This is accomplished by the use of...
Noise Sources of High Speed Maglev Trains
Noise is a major concern when any new transportation source is introduced into the existing surface transportation network. Maglev will be no exception. Despite the perception that there will be no problem in comparison with other noisy sources, such as diesel-hauled passenger and freight trains,...Noise Criteria for High Speed Maglev Trains
The introduction of a new transportation system into a community generates concerns about the change in the noise environment brought about by the new source. When the new source has unique features, as does maglev, or when the community has not had prior exposure to a particular source, as will...Measurements and Analysis of ELF Magnetic and Electric Fields for Existing and Advanced Rail Transportation Systems: Fifth Quarterly Progress Report
[From the Overview] This Quarterly Progress Report covers the effort on Contract DTFR- 53-91-C-00047, "Measurements and Analysis of ELF Magnetic and Electric Fields for Existing and Advanced Rail Transportation Systems" for the calendar months of June, July and August 1992. It is organized in four...Maglev System Concept Definition: Severe Segment Test Report
This report presents Foster-Miller Maglev system performance results and cost analysis for the Severe Segment Test (SST) stipulated by the government. The route design procedures are described and the resulting SST route geometries are defined for the two sets of requirements on ride quality ("...
