Sliding friction self-resetting energy dissipation damper with memory alloy ring
The invention discloses a sliding friction self-resetting energy dissipation damper with a memory alloy ring and belongs to the technical field of disaster prevention and shock absorption. The slidingfriction self-resetting energy dissipation damper with the memory alloy ring is mainly composed of an upper semicircular outer sleeve, a lower semicircular outer sleeve, wedge-shaped inner cores, endplates and the memory alloy ring, wherein the upper semicircular outer sleeve, the lower semicircular outer sleeve, the left wedge-shaped inner core and the right wedge-shaped inner core are made ofsteel with high strength; the left wedge-shaped inner core and the right wedge-shaped inner core are respectively welded with the left end plate and the right end plate; grooves matched with the shapes of the wedge-shaped inner cores are formed in the upper semicircular outer sleeve and the lower semicircular outer sleeve; the wedge-shaped inner cores are placed in the grooves of the upper semicircular outer sleeve and the lower semicircular outer sleeve; and the memory alloy ring is used for sleeving an upper semicircular outer sleeve ring and a lower semicircular outer sleeve ring. Accordingto the sliding friction self-resetting energy dissipation damper with the memory alloy ring, the requirements for deformation and bearing capacity of the structure under the action of the earthquakecan be met; the damper is simple in structure, clear in working mechanism and high in energy dissipation performance and self-resetting performance. The invention aims to solve the problems that post-earthquake maintenance and reconstruction costs are increased and the energy dissipation performance is insufficient because of excess residual deformation of the ordinary energy dissipation damper under the action of severe earthquake or medium earthquake.
一种记忆合金环滑移摩擦自复位耗能阻尼器，属于防灾减震技术领域。记忆合金环滑移摩擦自复位耗能阻尼器主要由上下半圆形外套管、楔形内芯、端板及记忆合金环构成。上下半圆形外套管和左右楔形内芯均为强度较高的钢材。左右楔形内芯分别与左右端板焊接。上下半圆形外套管内侧均有与楔形内芯形状吻合的凹槽，楔形内芯放置在上下半圆形外套管的凹槽里。记忆合金环将上下半圆形外套管环套在一起。本发明用可满足结构在地震作用下的变形和承载力要求。该阻尼器构造简单，工作机理明确，耗能性能与自复位性能能力强。本发明是为了解决普通耗能阻尼器在大震或中震作用下出现过量的残余变形而加大震后维护和重建成本以及耗能能力不足的问题。
