Abstract

The invention relates to the field of buildings, in particular to a speed amplification combined damping device and an eddy current damping wall. The speed amplification combined damping device comprises a rigid support, a rack, a first gear, levers, at least one stage of overdrive gear assembly and an eddy current damping assembly, wherein the rack is horizontally arranged, the first gear is meshed with the rack, one end of each lever is rotationally connected with the rigid support, the other end of each lever is rotationally connected with the rack, a connecting piece is hinged between every two adjacent levers, the connecting pieces are hinged to the levers through hinge shafts, the hinge shafts are located between first rotating shafts and second rotating shafts, the connecting piecescan drive the rack to be in meshing transmission with the first gear, the eddy current damping assembly is connected with the rigid support, and the overdrive gear assembly can drive the eddy currentdamping assembly to generate damping force. According to the speed amplification combined damping device, design and manufacturing of a large-tonnage damping wall can be achieved in a composite acceleration mode, the multiple speed amplification effect is achieved, and the energy consumption efficiency of the damping wall is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a speed amplification combined damping device and an eddy current damping wall. Background technique [0002] Under the action of wind and earthquake loads, the building will vibrate greatly, which will affect the safety and durability of the building. At present, structural vibration control has become the mainstream measure to reduce building vibration (vibration). In the field of structural vibration control, the damping wall is a passive energy dissipation and vibration reduction component, which is installed between building floors as a wall, and uses the relative movement between building floors to increase the damping of the structure to achieve energy dissipation and shock absorption. Compared with other energy dissipation and shock absorbing devices, the damping wall has the following advantages: [0003] (1) Easy to manufacture and install without complicated devices; [000...
