Self-resetting combined disc spring U-shaped metal energy dissipation damper with variable hysteresis performance
The invention relates to a variable hysteresis performance self-resetting combined disc spring U-shaped metal energy dissipation damper, and belongs to the technical field of civil engineering earthquake resistance. Comprising an outer sleeve, an inner sleeve, a combined disc spring and a U-shaped metal plate. The inner sleeve is sleeved with the outer sleeve, and the U-shaped metal plates are fixed to the inner side of the outer sleeve and the outer side of the inner sleeve. The inner sleeve comprises a first inner sleeve on the left side and a second inner sleeve on the right side; an inner sleeve left side baffle is further fixedly arranged on the left side of the first inner sleeve, a pair of inner sleeve outer side baffles is further slidably arranged on the first inner sleeve in a sleeving mode and arranged on the right side of the inner sleeve left side baffle and the left side of the second inner sleeve in a blocking mode, and a combined disc spring is further arranged on the portion, between the inner sleeve outer side baffles, of the first inner sleeve in a sleeving mode; two annular outer sleeve inner side baffles are further arranged in the outer sleeve and used for limiting the moving distance of the inner sleeve outer side baffles. The problems that a common energy dissipation damper is insufficient in energy dissipation capacity under the action of small earthquakes and has residual deformation under the action of large earthquakes or medium earthquakes are effectively solved.
本发明涉及一种变滞回性能自复位组合碟簧U型金属耗能阻尼器，属于土木工程抗震技术领域。包括外套管、内套管、组合碟簧以及U型金属板；内套管套设在外套管内部，U型金属板固定在外套管的内侧和内套管的外侧；内套管包括左侧的第一内套管以及右侧的第二内套管；第一内套管的左侧还固定设置有内套管左侧挡板，在第一内套管上还滑动套设有一对内套管外侧挡板，其分别挡设在内套管左侧挡板右侧以及第二内套管左侧，内套管外侧挡板之间的第一内套管上还套设有组合碟簧；外套管内还设置有两个环形的外套管内侧挡板，用于限制内套管外侧挡板的移动距离。本发明有效解决了普通耗能阻尼器在小震作用下耗能能力不足以及大震或中震作用下残余变形的问题。
