Abstract

This report discusses a propulsion and stabilization system comprising a series of figure 8 coils mounted vertically on the walls of the guideway to provide suspension, lateral guidance and propulsion of a magnetically levitated vehicle. This system further allows for altering the magnetic field effects by changing the relative position of the loops comprising the figure 8 coils either longitudinally and/or vertically with resulting changes in the propulsion, the vertical stability, and the suspension.

Design approaches and parameters for magnetically levitated transport systems. [Null flux suspension (Maglev)]

Conference Danby, G T; Powell, J R

Mechanically levitated transport system approaches are assessed with regard to thrust power needs, track cost, suspension stability, and safety. The null flux suspension appears as the favored approach, having the least thrust power requirements, highest stability, and lowest amount of track material. Various null flux configurations are described together with their operating parameters. The Linear Synchronous Motor (LSM) propulsion system is also described for propelling the suspended vehicles. Cryogenics and superconductivity aspects are discussed and the effect of high T/sub c/ superconductors evaluated. 13 refs., 16 figs., 2 tabs.

Propulsion and stabilization system for magnetically levitated vehicles

Patent Coffey, Howard T [Darien, IL]

A propulsion and stabilization system for an inductive repulsion type magnetically levitated vehicle which is propelled and stabilized by a system which includes propulsion windings mounted above and parallel to vehicle-borne suspension magnets. A linear synchronous motor is part of the vehicle guideway and is mounted above and parallel to superconducting magnets attached to the magnetically levitated vehicle.

Technical feasibility of magnetic levitation as a suspension system for high-speed ground transportation vehicles. Final rept. Feb 71--Feb 72, on Task 1

Technical Report Davis, L C; Reitz, J R; Wilkie, D F; ...

The technical feasibility of magnetic levitation was examined as a suspension system for high-speed ground transportation vehicles in the 300 mph cruise speed range. Of the various magnetic suspensions which have been proposed one appears to provide all the desired features of good ride quality, moderate guideway tolerance, basic stability, and moderate drag forces. This is high clearance (about 10 inch vehicle-track clearance) suspension using superconducting magnets in the vehicle and a conducting, nonmagnetic, continuous guideway. If a high tolerance track can be successfully laid and maintained, then a low clearance suspension using magnetic attraction forces such as being developedmore » « less
