The invention can improve the dynamic characteristics of the original structure, realizes the function of transferring and dissipating part kinetic energy which should be borne by the structure under the external dynamic action, and realizes dissipation of energy in multiple dimensions, thereby reducing the destructiveness of the original building structure.

Description

technical field [0001] The invention relates to a gyro damper for controlling multi-dimensional vibration of a structure and a manufacturing method thereof. The damper can perform tuning, energy consumption and shock absorption in the horizontal direction of the structure and in the torsional direction in the horizontal plane, and belongs to the technical field of anti-seismic, wind-resistant and vibration-absorbing structural engineering . Background technique [0002] With the continuous improvement of civil engineering theory and technical level, major building structures around the world are becoming large, complex and towering. Therefore, the structure is generally soft, and the deformation is relatively obvious under the action of environmental factors such as wind vibration and earthquake. The safety of the structure and the comfort of personnel have been severely tested. Facts have proved that under the action of wind load, the structure will produce complex vibrati...

Problems solved by technology

However, most of the current vibration control research is to simplify the structure into a plane model. The response of the structure under the action of a hurricane or earthquake is multi-dimensional, especially for an asymmetric structure. Failure to consider the multi-dimensional coupling vibration control will lead to vibration reduction. The effect is greatly reduced and cannot meet the needs of actual engineering
