Abstract:
1. A vehicle vibration suppression device for suppressing vibration of a vehicle body generated when a railway vehicle passes through a tunnel, comprising: a pair of ducts below a floor surface of the vehicle body, the pair of ducts being mounted adjacent to at least a pair of bogies on which the vehicle body is mounted, the ducts being arranged in a direction perpendicular to a traveling direction of the vehicle body and mounted so as to penetrate through both side surfaces of the vehicle body; a pressure control device mounted within each of the ducts, the pressure control device having openings, one of the openings serving as an intake port and the other opening serving as a discharge port, the pressure control device being configured to generate a pressure difference in each of the ducts; and a control unit for controlling start and stop of suction performed by the pressure control device while determining a side surface of the vehicle to be subjected to the suction by the pressure control device on the basis of current distance information of the railway vehicle during currently traveling, wherein the control unit suppresses vibration by driving the pressure control device and sucking a vortex caused by turbulence of air flow generated at a portion of the bogie when the railway vehicle passes through the tunnel.
