Self-resetting energy dissipation supporting device

Abstract

The invention provides a self-resetting energy dissipation supporting device. The self-resetting energy dissipation supporting device comprises a fixing frame, a supporting member and one or more pairs of self-resetting assemblies. The fixing frame comprises a fixing arm and two bearing arms, wherein one ends of the bearing arms are fixedly connected to a fixed arm and are parallel mutually; one end of the supporting member extends into the space between the two bearing arms and spaced with the fixing arm by a distance; the one or more pairs of self-resetting assemblies are symmetrically arranged on the two sides of the supporting member; and each self-resetting assembly comprises one or more shape memory alloys, each shape memory alloy is provided with two mutually parallel connecting arms and an energy dissipation arm connected to the two connecting arm, and every two connecting arms are connected to the supporting member and the corresponding bearing arm. The self-resetting energy dissipation supporting device has the good energy dissipation capability and the good self-resetting capability. 本发明提供一种自复位耗能支撑装置，包括固定架、支撑构件和至少一对自复位组件。固定架包括固定臂和一端固定连接于固定臂且相互平行的两个承载臂；支撑构件的一端伸入两个承载臂之间，且与固定臂之间间隔一距离；至少一对自复位组件对称设置于支撑构件的两侧；自复位组件包括一个或多个形状记忆合金，每个形状记忆合金具有两个相互平行的连接臂和连接于两个连接臂的耗能臂，两个连接臂分别连接于支撑构件和承载臂。本发明具有良好的耗能能力和自复位能力。
