Abstract

The invention provides a damper support platform for vibration reduction by utilizing the mass of furniture and household appliances, which belongs to the field of vibration reduction of civil engineering structures. Based on the vibration reduction control principle of the tuned mass damper, the invention uses the mass of furniture and household appliances as the mass of the damper, and designs a mechanism consisting of a cap, a ball slide, a spring and a viscous damper. The tuning mass is changed to the tuning stiffness through the detachable spring, thereby adjusting the natural vibration period of the overall system in combination with the quality of furniture and household appliances. Although the furniture damper cap adopts the TMD principle, it does not add unnecessary additional mass to the building structure. It can be used for washing machine bases, refrigerator bases, bed bases, etc., so that the necessary furniture and household appliances in the building can be used to repair the structure. Vibration control.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of civil engineering structures, and relates to the design of a shock absorber composed of a bearing platform, a ball slideway, a spring and a viscous damper for a building structure. Background technique [0002] The traditional seismic design of structures is to "resist" earthquake action by enhancing the performance of the structure itself. However, because people cannot accurately estimate the earthquake intensity and characteristics that the structure may encounter in the future, under the action of strong earthquakes, the structure may not meet the safety requirements, resulting in serious damage or even collapse. The emergence of structural vibration control technology provides an effective way to improve the safety of building structures under strong earthquakes. A tuned mass damper (Tuned Mass Damper, TMD) is a common vibration reduction device, by tuning the additional mass ...
