Shape memory alloy composite friction damper and design method and application thereof
The invention discloses a shape memory alloy composite friction damper and a design method and application thereof.The shape memory alloy composite friction damper comprises an outer frame and an inner frame which can slide relatively, and the outer side of the outer frame and the outer side of the inner frame are connected with a first force transmission plate and a second force transmission plate correspondingly; two groups of SMA rod damping structures with opposite deformation directions are connected between the inner frame and the outer frame, each SMA rod damping structure comprises an SMA rod, an anti-buckling steel sleeve is arranged on the outer side of each SMA rod, and fillers are arranged between the SMA rods and the anti-buckling steel sleeves. The shape memory alloy and the friction device are combined, the shape memory alloy provides self-resetting capacity, and the friction device provides energy dissipation capacity. And the energy dissipation capacity of the damper can be adjusted, and the problem that the self-resetting capacity of the damper is insufficient after the earthquake action is effectively solved.
本发明公开了一种形状记忆合金复合摩擦阻尼器及其设计方法和应用，本发明的形状记忆合金复合摩擦阻尼器包括能够相对滑动的外框架和内框架，所述外框架和内框架的外侧分别连接有传力板一和传力板二；所述内框架和外框架之间连接有两组形变方向相反的SMA棒阻尼结构，每个所述SMA棒阻尼结构包括一个SMA棒，所述SMA棒外侧设置有防屈曲钢套筒，所述SMA棒和所述防屈曲钢套筒之间设置有填料。本发明将形状记忆合金与摩擦装置结合，由形状记忆合金提供自复位能力，由摩擦装置提供耗能能力。且该阻尼器耗能能力可以调节，有效解决阻尼器在地震作用后的自复位能力不足的问题。
