This paper deals with a
study on the dynamic behavior of 600 km/h wheel-type train propelled by
superconducting linear synchronous motor (LSM). This train is of a traditional
wheel-on-rail type with traction motors on wheel-bogies. However, for the 600 km/h
speed, on the both sides of each vehicle, superconducting LSMs are attached and
the ground coils are installed on the guideway. In this case, the guideway
irregularities act as disturbance to the vehicle causing deterioration of ride
comfort. And besides thrust force, the normal force could be created in superconducting
LSM control, which influences vehicle dynamics during running. In this study,
to examine the effect of guideway irregularity and normal force on dynamic
behavior of proposed train, the vehicle dynamic model is driven and frequency
analysis is performed through simulation. The simulation results show that the
lateral directional acceleration is mainly influential to ride comfort; however
this could be reduced effectively by electromagnetic damping force from linear
generator. It is also shown that the normal force effect from superconducting
LSM control is limited even though the attractive normal force acts favorably
to ride comfort.
