PROBLEM TO BE SOLVED: To ensure attenuation force of a damper even in a case of arranging the damper in a vertical direction.SOLUTION: A vibration control system includes: an upper structure part fixed to a vibration control object; a first mass body suspended from the upper structure part; a lower structure part fixed to vibration control object; a second mass body supported to the lower structure part; a connection member constraining the first mass body and the second mass body in a horizontal direction while allowing relative displacement in a vertical direction between the first mass body and the second mass body; and a damper arranged in the vertical direction between the first mass body and the second mass body. The damper has a large attenuation coefficient when the relative speed in the vertical direction between the first mass body and the second mass body is made small, and has a small attenuation coefficient when the relative speed is made large.SELECTED DRAWING: Figure 6 |
