Multidimensional wave-surface thick viscoelastic layer vibration/shock isolation and attenuation device

Abstract

The invention provides a multidimensional wave-surface thick viscoelastic layer vibration / shock isolation and attenuation device which comprises an upper steel plate, a lower steel plate and a wave-surface viscoelastic support clamped between the upper steel plate and the lower steel plate, wherein wave-surface viscoelastic support comprises a top plate fixed on the lower surface of the upper steel plate, a base plate fixed on the upper surface of the lower steel plate and a wave-surface laminated support located between the top plate and the base plate; the wave-surface laminated support is formed by alternately laminating and vulcanizing viscoelastic material layers and steel plates with elliptical bulges on the upper and lower surfaces in sequence. Under a condition of guaranteeing a horizontal vibration isolation effect in the horizontal direction, the horizontal ultimate deformation resistance of the device is enhanced; under a condition of guaranteeing the bearing capacity in the vertical direction, the vertical rigidity is reduced, and the vibration isolation effect is improved; furthermore, by the sectional design, relatively high vertical damping is obtained.

Description

technical field [0001] The invention relates to a structure vibration control device, in particular to a multi-dimensional isolation vibration reduction / vibration device. Background technique [0002] With the development of economy and social progress, there are more and more high-rise buildings, long-span structures, important building facilities, and structures with irregular shapes (such as structures with long overhangs); at the same time, urban rail transit is booming, high-speed railways, Underground railways and other large-scale construction. Under the action of dynamic loads (earthquakes, strong winds, vibration loads under orbital operation, etc.), the building structure vibrates, which can easily lead to a decrease in the comfort level of the structure, a decrease in safety, or even damage. How to reduce complex and changeable vibration effects has become an important issue. . Structural vibration control is a new type of anti-vibration / seismic measure, which c...
