Description
Technical Field

Background
Compared with a wheeltrack train, the magnetic levitation train has the remarkable characteristics of safety, economy, silence, environmental protection and the like. The cost per kilometer and the operation and maintenance cost of the middle-low speed magnetic levitation train are lower than those of the subway and the light rail. At present, a magnetic levitation train commercial operation line exists in the long sand, the magnetic levitation train operation line is opened by Beijing, and the middle-low speed magnetic levitation train operation line is planned in the capital area.
The wheel tread of the wheel rail train is conical, so that the wheel rail train has an automatic centering function, and the wheels can automatically center the rail under the action of gravity of the vehicle body when being deflected to one side due to the disturbance of the rail irregularity. The current magnetic levitation train has no transverse force and no restoring force in the horizontal plane, no automatic centering function, and the used F-rail middle-low speed magnetic levitation train has weak centering function but cannot be adjusted in size, and the F-rail and levitation structure (CN 201320278221) of the magnetic levitation train and the paper are referred to the research and analysis of the novel middle-low speed magnetic levitation train running mechanism with 140km per hour.
The magnetic levitation track is inclined, so that the levitation force is not vertically upwards any more, and therefore transverse component force is generated, and the transverse component force of the levitation forces at the two sides is adjusted in real time, so that the levitation frame is controlled in the middle of the track.
