To provide a vibration control system using a runaway prevention device of a track running-type machine capable of efficiently absorbing impact of rocking phenomenon during an earthquake by modifying an existing device, and capable of reducing cost.SOLUTION: A vibration control system comprises a runaway prevention device 40 including: a running gear 8 on which rotatable running wheels 7 are arranged along a rail 4; a fluid pressure cylinder 13 which freely presses/separates a brake pad 12 in a direction orthogonal to the rail 4 against/from a running wheel rolling surface 4a of the rail 4; and a fluid pressure unit 14 which guides working fluid to the fluid pressure cylinder 13 and presses the brake pad 12 against the running wheel rolling surface 4a of the rail 4. Furthermore, the vibration control system comprises a fluid pressure shock absorber installed between the fluid pressure cylinder 13 and the fluid pressure unit 14 to absorb the landing shock after the running gear 8 is lifted when an earthquake occurs.SELECTED DRAWING: Figure 1

    【課題】既存の装置の改造により地震発生時のロッキング現象における衝撃を効率良く吸収し得、コスト削減を図り得る軌道走行式機械の逸走防止装置を用いた制振システムを提供する。【解決手段】レール4に沿って転動自在な走行車輪7が配設された走行装置8と、レール4の走行車輪転動面4aに対しレール4と直交する方向へブレーキパッド12を押付・離反自在な流体圧シリンダ13と、作動流体を流体圧シリンダ13へ導いてブレーキパッド12をレール4の走行車輪転動面4aに押し付ける流体圧ユニット14とを含む逸走防止装置40を備え、更に、走行装置8の地震発生時における浮き上がり後の着地時に発生する衝撃を吸収するよう流体圧シリンダ13と流体圧ユニット14との間に設けられる流体圧緩衝装置を備える。【選択図】図1
