<p>PROBLEM TO BE SOLVED: To provide a vibration control device that reduces vibration and noise to a nearby area of a railroad line by suppressing a vibration generating in a train according to a vibration situation when the train is passing and also lighten the load placed on a track structure to contribute to suppression in track maintenance amount and improvement in comfortableness to ride in a train.SOLUTION: A vibration control condition setting part 17 sets vibration control conditions for reducing vibration by an elastic support part 10. A spring rigidity variation part 22 varies spring rigidity of the elastic support part 10 based upon the vibration control conditions set by the vibration control condition setting part 17. When the vibration control condition setting part 17 sets a rail priority vibration control mode, the spring rigidity variation part 22 varies the spring rigidity of the elastic support part 10 so that vibration on the side of a rail 5 is reduced. When the vibration control condition setting part 17 sets a roadbed priority vibration control mode, the spring rigidity variation part 22 varies the spring rigidity of the elastic support part 10 so that vibration on the side of a roadbed 8 is reduced.</p> |
