Abstract: A state-of-the-art review on maglev vehicle/ guide- way
system dynamics including modeling, numerical simulation and dynamic
performance evaluation is presented. As maglev train technology advanced
towards the level of commercial application, dynamic simulations of
maglev vehicle/guideway system used more detail and complex coupling
models. And great progress is made in studies on the maglev vehicle/guideway
vertical interaction, curve negotiation and random vibration. In the
future, the large system model considering the bogie structure, the
levitation and guidance control system, aerodynamic effect and linear
motor force should be established to simulate truly dynamic behaviors of
maglev train system, which make it necessary to explore new
high-efficient numerical method solving the nonlinear time-varied
differential equations of maglev vehicle/guideway controller system.
Furthermore, studies on the experimental verifications of dynamic model
and simulation, the maglev train longitudinal dynamics, the dynamic
optimization of maglev train system, and the specifications for
evaluating dynamic performances should be carried out as soon as
possible.
