Fabricated foamed aluminum-based composite material-extruded lead composite damper and anti-seismic device
The invention discloses a fabricated foamed aluminum-based composite material-extruded lead composite damper and an anti-seismic device, and belongs to the technical field of engineering structure seismic resistance and energy dissipation and shock absorption. The damper comprises an upper sleeve and a lower sleeve, a cavity is formed between the upper sleeve and the lower sleeve, lead blocks are arranged in the upper sleeve and the lower sleeve, a middle pressing plate is arranged in the cavity, foamed aluminum-based composite materials are fixed between the middle pressing plate and the upper sleeve and between the middle pressing plate and the lower sleeve, and a push-pull rod penetrates through the upper sleeve, the lower sleeve, the middle pressing plate and the lead blocks in the upper sleeve and the lower sleeve. The parts, located in the upper sleeve and the lower sleeve, of the push-pull rod are provided with shaft protrusions, and the push-pull rod drives the middle pressing plate and the shaft protrusions to move synchronously. When the composite damper vibrates in a small displacement mode, the foamed aluminum-based composite material plays a role in energy dissipation, and the structure can be effectively prevented from shaking; and during large-displacement vibration, the extrusion lead block and the foamed aluminum-based composite material jointly participate in energy consumption, a good damping energy consumption effect is achieved, and therefore shock absorption is effectively conducted on the structure.
本发明公开了一种装配式泡沫铝基复合材料‑挤压铅复合型阻尼器及抗震装置，属于工程结构抗震与消能减震技术领域。本发明的阻尼器包括上套筒、下套筒，所述的上、下套筒之间形成一腔室，所述的上、下套筒内均设有铅块，腔室内设有中间压板，该中间压板与上、下套筒之间均固定有泡沫铝基复合材料，推拉杆贯穿上、下套筒、中间压板以及上、下套筒内的铅块，该推拉杆位于上、下套筒内的部分设有轴突，推拉杆带动中间压板、轴突同步移动。本发明的复合型阻尼器在小位移振动时，泡沫铝基复合材料发挥耗能作用，能有效地防止结构晃动；而在大位移振动时，挤压铅块和泡沫铝基复合材料共同参与耗能，起到很好的阻尼耗能作用，从而有效地对结构进行减震。
