Abstract

The invention relates to a distributed type fan blade type tuned mass damper device which comprises a fixed base (4) and control units distributed around the fixed base (4) in a fan blade shape. Each control unit comprises a cantilever (1), a balance weight (2) and a viscous damper (3), wherein one end of the cantilever (1) is connected with the viscous damper (3), the other end of the cantilever (1) is connected with the balance weight (2), and the cantilever (1) and the viscous damper (3) are fixed to the fixed base (4). The fixed base (4) is detachably connected with the control units, and a flat damper structure is formed. Compared with the prior art, the distributed type fan blade type tuned mass damper has the advantages of being small in size, convenient to install and the like.

Description

technical field [0001] The invention relates to the field of structural vibration control in construction engineering, in particular to a distributed fan-type tuned mass damper device, which is mainly aimed at human activities such as walking, jumping and running of users in buildings and indoor forklifts, Structural floor vibration caused by power equipment such as air-conditioning compressors and machine tools on the floor. Background technique [0002] The vibration of the floor structure caused by users walking, jumping, running, dancing, stepping, instant standing or sitting down, flexion and extension, clapping and other actions is called human-induced vibration. In addition, in industrial and public buildings, there may be small forklifts running on the floor, and power equipment such as air-conditioning compressors, purifiers, and processing machine tools may be arranged at the same time. These equipment will also cause vibration of the floor when they are running. ...
