Mass tuning type vibration reduction multi-pendulum structure with air springs and damping particles

A mass tuning type vibration reduction multi-pendulum structure with air springs and damping particles mainly comprises a rigid hanging rod, tuning mass balls, the air springs, anchoring bolts, a top hinged seat, reserved filling holes and the damping particles. The device is connected with a structural floor. By using the characteristic that the period, mass, pendulum length and rigidity of the multi-pendulum structure are all related, the mass of the tuning mass balls, the length of each section of the hanging rod, rigidity of the air springs and the overall damping of the damping particles are reasonably set, so that the multiple natural vibration periods of the mass tuning type vibration reduction multi-pendulum structure is equal to or close to the corresponding multi-order period of the structure, and accordingly tuning vibration reduction control over the structural multi-vibration mode is achieved and dynamic response of a structural body under earthquakes and wind loads is reduced. 种具有空气弹簧和阻尼颗粒的质量调谐式
