ANTI-VIBRATION APPARATUS FOR VERTICAL VIBRATION OF STRUCTURE

摘要: PROBLEM TO BE SOLVED: To provide anti-vibration apparatus for vertical vibration which enables regulation of natural frequency within wide limits in terms from a low limit to high thereof. SOLUTION: A pair pendulums (10) comprise, respectively, an arm (12) installed revolvably on horizontal axis (11) attached column part (53) the structure and oscillating body (13) mounted tip portions adjustably angularly. The are supported form balancing toy by means spring (14) arranged between bodies right left connectably adjusting allow pendulum oscillation based position slanted roof center is projected upward as reference damper (15) disposed pain arms damping. can be regulated over range controlling length arm, angle inclination installation constant spring.
