Vertical vibration reduction support and vibration reduction method thereof

Abstract

The invention provides a vertical vibration reduction support. The vertical vibration reduction support comprises an upper seat plate, a middle seat plate and a lower seat plate which are sequentially stacked and connected from top to bottom. The vertical vibration reduction support is characterized in that a multi-frequency vibration absorption assembly capable of absorbing multi-frequency vibration is arranged in the middle seat plate, the multi-frequency vibration absorption assembly is correspondingly in elastic contact with the upper seat plate and the lower seat plate and synchronously deforms along with relative vertical movement of the upper seat plate and the lower seat plate, and the upper seat plate, the middle seat plate and the lower seat plate all have damping characteristics. Vibration of various frequencies can be absorbed, the defect that an existing vertical support is single in vibration absorption frequency is overcome, the damping capacity and the vertical deformation capacity of the whole support are higher, the vibration reduction efficiency of the support is effectively improved, the damping capacity and the vertical deformation capacity are higher, the support is simple in internal structure and not prone to being damaged, and the service life of the support is prolonged. The invention further provides a vibration reduction method of the vertical vibration reduction support.

Description

technical field [0001] The invention relates to a vertical vibration-damping support and a vibration-damping method thereof, belonging to the technical field of supports. Background technique [0002] The ground vibration induced by subway is mainly vertical vibration. For buildings adjacent to rail transit, when the vertical vibration exceeds the national standard limit, necessary vibration reduction measures must be taken, especially for buildings with high vibration requirements such as theaters, concert halls, museums, and cutting-edge laboratories. The control of environmental vibration and noise has become a problem that must be solved in the design of building structures. [0003] CN212453169U discloses a device for vertical vibration isolation and horizontal vibration isolation for buildings, including a vertical vibration isolation mechanism and a horizontal vibration isolation mechanism, wherein the vertical vibration isolation mechanism is used to reduce vertical...
