High-damping multi-direction wide-frequency-domain anti-drawing shock isolation and absorption device and shock isolation and absorption method
The invention discloses a high-damping multi-direction wide-frequency-domain anti-drawing shock isolation and absorption device and a shock isolation and absorption method. The device is composed of an upper steel cylinder, a lower steel cylinder, a lower shock isolation and absorption unit, an upper shock isolation and absorption unit and a fluid damping material. Under the action of an earthquake or vibration, shock isolation and shock absorption are conducted through shear deformation by the lower shock isolation and absorption unit in the horizontal direction, and vibration transmission is isolated and vibration energy is consumed through compression deformation of the spring and the viscoelastic cushion in the vertical direction. In addition, innovative design of fluid damping materials, annular bosses, damping round holes and the like is adopted in the device, the damping ratio in multiple directions is increased, and the technical problems of drawing resistance, torsion resistance and the like are solved. The device can effectively cope with multidirectional and broadband complex vibration disasters generally existing in the service period of an engineering structure, has the advantages of being clear in stress process, convenient and fast to machine and manufacture and the like, and is easy to apply and popularize in engineering.
本发明公开了一种高阻尼多方向宽频域抗拉拔隔减震装置及隔减震方法，装置由上钢筒、下钢筒、下部隔减震单元、上部隔减震单元和流体阻尼材料组成。在地震或振动作用时，水平方向由下部隔减震单元通过剪切变形隔震和减震，竖向通过弹簧和粘弹性垫的压缩变形隔离振动传递并消耗振动能量。此外，装置采用了流体阻尼材料，环向凸台，阻尼圆孔等创新性设计，增加了多方向的阻尼比，解决了抗拉拔和抗扭转等技术难题。本装置可有效应对工程结构服役期间普遍存在的多方向、宽频域复杂振动灾害，并具有受力过程明确，加工制造便捷等优势，易于在工程中推广应用。
