PROBLEM TO BE SOLVED: To provide a vibration suppression control apparatus by which riding comfortableness is not deteriorated even if a passage flow quantity of a hydraulic oil in a hydraulic circuit is small.SOLUTION: A vibration suppression control apparatus for a railway vehicle comprising a cylinder 10 for vibration suppression control provided between a carriage 153 and a vehicle body 151, and a reservoir tank 20 which connected to a head side chamber 13 of the cylinder 10 for vibration suppression control, in which in the case that a vibration detected by an acceleration sensor 160 in a first on-off valve 61 and a second on-off valve 62 which are connected to a controller 90 is larger than a first threshold, the first on-off valve 61 and the second on-off valve 62 so control that a hydraulic oil pass through a third flow channel R3 or a fourth flow channel R4, and in the case vibration detected by the acceleration sensor 160 is equal to or smaller than the first threshold, the first on-off valve 61 and the second on-off valve 62 so control that the hydraulic oil pass through a first flow channel R1 or a second flow channel R2 by means of the controller 90.SELECTED DRAWING: Figure 1
【課題】油圧回路内の作動油の通過流量が少ない場合にも乗り心地を悪化させない制振制御装置の提供。【解決手段】台車153と車体151との間に備えられる制振制御用シリンダ10と、制振制御用シリンダ10のヘッド側室13に接続されたリザーバタンク20と、を備えた鉄道車両用の制振制御装置において、コントローラ90に接続された第1オンオフ弁61及び第2オンオフ弁62で、加速度センサ160が検出する揺れが第1閾値より大きい場合、第1オンオフ弁61及び第2オンオフ弁62が第3流路R3又は第4流路R4を作動油が通過するように制御し、加速度センサ160が検出する揺れが第1閾値以下の場合、コントローラ90によって第1オンオフ弁61及び第2オンオフ弁62が第1流路R1又は第2流路R2に作動油が通過するように制御する。【選択図】図1
