Adjustable self-resetting variable cross-section friction energy consumption device
The invention provides an adjustable self-resetting variable cross-section friction energy consumption device, which belongs to the technical field of structural engineering, and comprises a sleeve assembly and two variable cross-section steel bars which are symmetrically inserted in the sleeve assembly front and back; a first conical surface, a first equal-diameter section, a second conical surface and a traction rod are sequentially arranged on each of the two variable-cross-section steel bars from the opposite end to the end far away from the opposite end; the diameters of the two first conical surfaces are gradually reduced from the opposite ends to the ends far away from each other; load is transmitted to the variable cross-section steel bar through the steel structure, the variable cross-section steel bar generates reciprocating motion of the two ends in the axial direction under reciprocating pull pressure, due to the fact that the variable cross-section steel bar is attached to the inner side of the fan-shaped cover plate, force in the axial direction is converted into force in the vertical direction, under the effect of the SMA wires, the fan-shaped cover plate is hooped again and attached to the variable cross-section steel bar, and then the fan-shaped cover plate is fixed. And the variable cross-section steel bar is not easy to deform and can continuously work.
本发明提供一种可调式自复位变截面摩擦耗能装置，属于结构工程技术领域，该一种可调式自复位变截面摩擦耗能装置包括套管组件和两个前后相互对称插设在套管组件内的变截面钢棒；两个变截面钢棒从相对一端到相远离一端依次设置有第一锥形面、第一等径段和第二锥形面和牵引杆；两个第一锥形面的直径从相对一端到相远离的一端逐渐减小；荷载通过钢结构传给变截面钢棒，变截面钢棒受到往复拉压力产生两端沿轴向方向的往复运动，由于变截面钢棒与扇形盖板内侧贴合，将轴向方向的力转变为竖向方向的作用下，在SMA丝的作用下，将扇形盖板进行重新箍紧，与变截面钢棒贴合，使变截面钢棒不容易发生变形，能够继续工作。
