Abstract (en)

[origin: EP2020356A2] A vibration suppression device that suppresses vibration in a railway vehicle 1 includes a damper 9 having a variable damping force, which extends and compresses in accordance with lateral vibration of a vehicle body 10 relative to a bogie 3, first control means that control the damping force of the damper 9 using sky-hook semi-active control in order to suppress the lateral vibration of the vehicle body 10, vertical direction acceleration detecting means 15 that detect acceleration in a vertical direction of the vehicle body 10, determining means that determine whether or not lateral vibration has occurred in the bogie 3 on the basis of the acceleration detected by the vertical direction acceleration detecting means 15, second control means that cause the damper 9 to operate so as to suppress the lateral vibration of the bogie (3), and switching control means that switch from the first control means to the second control means when lateral vibration is determined to have occurred in the bogie 3.
