Embodiment Construction
[0021] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.
[0022] Example: such as figure 1 , 2 As shown, a multi-dimensional wave surface thick viscoelastic layer isolation vibration reduction / vibration device includes an upper steel plate 1 and a lower steel plate 2 arranged horizontally up and down, and a wave surface viscoelastic support 9 arranged between the upper steel plate 1 and the lower steel plate 2 . The wave surface viscoelastic support 9 includes a top plate 3, a bottom plate 4, and a wave surface laminated support between the top plate 3 and the bottom plate 4. The top plate 3 is fixed and attached to the lower surface of the upper steel plate 1 by bolts 7, and the bottom plate 4 is fixed by bolts 7. Attached to the upper surface of the lower steel plate 2, the corrugated laminated support is formed by alternately laminating and vulcanizing v...

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 damping / vibration device, in particular to a multi-dimensional vibration damping / 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 consumes or i...
