PROBLEM TO BE SOLVED: To provide a stationary acceleration speed detection device which can detect the stationary acceleration speed with high accuracy, and a vibration damping device for railway vehicle which can improve the riding comfort at the travel in the curve section.SOLUTION: A stationary acceleration speed detection device D obtains the stationary acceleration speed αc on the basis of the filtered yaw acceleration speed ω' and filtered sway acceleration speed β' subjected to the low-pass filter processing. A vibration damping device V for railway vehicle obtains the control forces Ff, Fr on the basis of the centering force fn and the suppression forces ff, fr obtained on the basis of the stationary acceleration speed αc when the stationary acceleration speed αc detected by the stationary acceleration speed detection device D is equal to or greater than a centering threshold α1.SELECTED DRAWING: Figure 3
