PURPOSE:To provide a viscous damper device which gives no static or semi- static deformation to a structure by sealing a container with viscosity fluid with no bubbles. CONSTITUTION:This viscous damper device 1 is subjected to bubble venting, where no bubbles exist in viscous fluid 4. A no-contact type displacement meter measures the displacement of a gate stage 5 near a damper mounting position. With no damper attached (A), it reaches Z which is a target value, however, it is vibrational. In the case of a conventional viscosity damper device (B), attenuation is restrained, however, a static or semi-static deformation DELTAZ exists by a restoring force. In the case of this viscosity damper device (C), no static or semi-static deformation DELTAZ exists. Attenuation restraint is also realized. |
