Self-resetting damper based on SMA (Shape Memory Alloy)
The invention discloses a self-resetting damper based on SMA. The self-resetting damper comprises a sleeve assembly, a fixing piece, an energy consumption wire and a prestress clamp. The sleeve assembly comprises an inner barrel and an outer barrel, the outer barrel is arranged on the outer side of the inner barrel in a sliding and sleeving mode, and a guide groove is formed in the inner barrel. The end of the fixing piece is fixed to the outer barrel, and the fixing piece penetrates through the guide groove and can slide along the guide groove. The energy consumption wires comprise the first energy consumption wire and the second energy consumption wire. The first end of the first energy consumption wire is fixed to the first end of the inner barrel, and the second end of the first energy consumption wire is fixed to the fixing piece. The first end of the second energy consumption wire is fixed to the second end of the inner barrel, and the second end of the second energy consumption wire is fixed to the fixing piece. At least one end of the first energy consumption wire and/or the second energy consumption wire is fixed through a prestress clamp. Compared with the prior art, the energy dissipation wire is pre-stretched, the average damping force in the deformation process of the energy dissipation wire can be improved, and therefore the dissipation capacity of vibration energy is improved.
本发明公开了一种基于SMA的自复位阻尼器，包括套筒组件、固定件、耗能丝和预应力卡具。套筒组件包括内筒体和外筒体，外筒体滑动套设于内筒体外侧，内筒体上设有导向槽。固定件的端部固定于外筒体上，固定件穿过导向槽并能够沿导向槽滑动。耗能丝包括第一耗能丝和第二耗能丝。第一耗能丝的第一端固定于内筒体的第一端，第一耗能丝的第二端固定于固定件上。第二耗能丝的第一端固定于内筒体的第二端，第二耗能丝的第二端固定于固定件上。其中，第一耗能丝和/或第二耗能丝的至少一端通过预应力卡具固定。相比于现有技术，本发明通过对耗能丝进行预拉伸，能够提高其变形过程的平均阻尼力，从而提高对震动能量的耗散能力。
