Abstract:
Dynamic
responses of maglev vehicle/guideway system have important influence on
running safety, ride comfort and system costs, which are crucial factors
for maglev train commercial application. As the first part of the series
paper, the essential issue of maglev vehicle/guideway system dynamics is
discussed, including the magnet/rail interaction and the dynamic
stability. Remarkable advance has been made on the 2-diemesional
theoretical analysis and dynamic simulation of magnet/rail interaction.
It is necessary to carry out theoretical analyses and experimental
studies on the 3-diemensional magnet/rail interaction in the future. The
magnet suspension stability, single magnet/guideway system stability and
dynamic stability of simple maglev vehicle/guideway system had been
investigated in the past thirty years. In order to meet the demand of
developing the commercial maglev system, it is suggested to investigate
as soon as possible the dynamic stability of the full-scale maglev
vehicle/guideway system.
Key words: Maglev vehicle Elevated-beam Coupling dynamics
