Multi-dimensional vibration isolation and damping device with multi-directional anti-drawing and pre-tightening functions and vibration isolation and damping method thereof
A pre-tightening and pull-out technology, applied in building components, building types, earthquake-proof, etc., can solve the problem of inability to observe changes in device performance in real time, poor vertical pull-out and torque performance, and multi-dimensional vibration isolation and torsional effects. It can achieve the effect of clear force transmission and energy consumption mechanism, enhanced overall deformation ability, and reasonable structure

Example Embodiment
[0049] Example 1
[0050] The preloaded cylindrical damper 5 is located between the upper and lower pressure-bearing steel plates, and a total of four preloaded cylindrical dampers are used, which are installed symmetrically and evenly around the core damping pad.
[0051] The steel plate layer 2 of the core damping pad and the viscoelastic material layer 3 of the core damping pad are laminated in sequence, and vulcanized under high temperature and high pressure to form the core damping pad (that is, the arrangement rule of the viscoelastic material and the steel plate is the interlayer arrangement, similar In the "sandwich" structure.) It is also located between the upper and lower bearing steel plates and is installed in the center of the upper and lower bearing steel plates. Among them, the preloaded cylindrical damper 5 is mainly used to attenuate the vibration in the vertical direction, and the preloading spring 10 is used to provide preloading force, so as to withstand a larg...
Example Embodiment
[0074] Example 2
[0075] In this embodiment, the viscoelastic material in the pre-compressed cylindrical damper 5 is replaced with foamed aluminum.
Example Embodiment
[0076] Example 3
[0077] In this embodiment, the viscoelastic material layer 3 of the core damping pad is replaced with rubber.
