Damper bearing table for vibration reduction by using mass of furniture and household electric appliances

一种利用家具及家用电器质量来减振的阻尼器承台

Abstract

The invention provides a damper bearing table for vibration reduction by using the mass of furniture and household electric appliances, and belongs to the field of civil engineering structure vibration reduction. A mechanism consisting of bearing tables, a ball bearing slideway, springs and viscous dampers is designed by using the mass of the furniture and the household electric appliances as the mass of a damper on the basis of a TMD (Tuned Mass Damper) vibration reduction control theory. The tuned mass is changed into the tuned rigidity through the dismountable springs, so that the natural vibration period of the whole system is regulated by combining the mass of the furniture and the household electric appliances. The furniture and household electric appliance damper bearing table has the advantages that the TMD theory is used, but the unnecessary additional mass of a building structure is not increased; and the damper bearing table can be used for a washing machine base, a refrigerator base, a bed base and the like, so that the necessary furniture and the necessary household electric appliances in a building are used for vibration reduction on the structure.
本发明提供了一种利用家具及家用电器质量来减振的阻尼器承台,属于土木工程结构减振领域。本发明基于调谐质量阻尼器减振控制原理,利用家具及家用电器质量作为阻尼器的质量,设计了承台、滚珠滑道、弹簧、粘滞阻尼器组成的机构。通过可拆卸弹簧改变了调谐质量为调谐刚度,从而结合家具及家用电器质量调节了整体系统的自振周期。该家具家电阻尼器承台虽然采用TMD原理,但不增加建筑结构不必要的附加质量,可用于洗衣机底座、冰箱底座、床底座等等,从而利用建筑中必要的家具及家用电器来对结构进行减振控制。
