摘要： A vibration control device for railroad vehicle includes an actuator with a cylinder coupled to a truck of a railroad vehicle, a piston, a rod coupled to the piston and a vehicle body, a rod-side chamber and a piston-side chamber in the cylinder, a tank, a first on-off valve disposed at an intermediate position of a first passage communicating between the rod-side chamber and the piston-side chamber, a second on-off valve disposed at an intermediate position of a second passage communicating between the piston-side chamber and the tank, and a pump for supplying fluid to the rod-side chamber. A warm-up operation of the actuator is performed by opening the first and second on-off valves and driving the pump after the vibration control device is started and before a transition is made to a normal control mode for suppressing the vibration of the vehicle body.
