Abstract

The invention discloses a variable damping type tuning mass damper arrangement mechanism, which includes a mass ball, a first guide rod, a second guide rod, a fixed support, N first cavities and N second cavities; One cavity is fixed on one side of the fixed support sequentially along the horizontal direction, each second cavity is fixed on the other side of the fixed support sequentially along the horizontal direction, one end of the first guide rod is fixed on one side of the outer wall of the mass ball, The other end of the first guide rod passes through the N-1 first cavities in turn and is inserted into the Nth first cavity, one end of the second guide rod is fixed on the other side of the outer wall of the mass sphere, and the second guide rod The other end passes through the N-1 second cavities in turn and is inserted into the Nth second cavity. This mechanism has an obvious shock-absorbing effect in the case of low-intensity ground vibrations, and it is also effective in the case of high-intensity ground vibrations. Not easy to be destroyed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and mechanical engineering, and relates to a variable damping type tuning mass damper arrangement mechanism. Background technique [0002] Structural shock absorption control is to reduce or suppress the response of the structure due to external loads by installing energy-dissipating shock-absorbing devices on the structure. It is mainly used in the field of civil engineering for energy-dissipating shock absorption of buildings. As a shock absorbing and energy dissipating device, a tuned mass damper (TMD) has been widely used in various high-rise or super high-rise buildings due to its stable and reliable performance. However, due to the simple damping provided by the traditional tuned mass damper, the control effect is not obvious under the action of small-intensity earthquakes, and the excessive intensity of earthquakes may cause damage to the device.
