Torsion-resistant damper with self-resetting function
The invention belongs to the field of civil engineering energy dissipation, shock absorption and disaster prevention and reduction control, and relates to an anti-torsion damper with a self-resetting function, which mainly comprises a shell plate, a rubber block, a mass block, a slide rail, a lug plate a, an SMA beam, a lug plate b, a connecting rod, a steel rod, a partition plate, a rivet, an upper cover plate, a roller, a lower cover plate and a bolt pin. The problems that a restorable damper is low in energy consumption efficiency and can only achieve a damping effect on torsional vibration of a single frequency band are effectively solved. The SMA beam and the lever structure are adopted, small torsional displacement is amplified, and the energy consumption efficiency is remarkably improved; the force transmission mechanism is clear and reasonable, and the torsional motion of the mass block is effectively converted into the stretching of the SMA beam; the whole structure is in central symmetry, so that the influence of the eccentric distance on the structure can be effectively reduced; the device is reasonable in design, simple in structure, low in cost and convenient to mount, and can be applied to building structures in rows and groups.
本发明属于土木工程耗能减震与防灾减灾控制领域，涉及到一种具有自复位功能的抗扭阻尼器，主要由外壳板、橡胶块、质量块、滑轨、耳板a、SMA束、耳板b、连杆、钢杆、隔板、铆钉、上盖板、滚轮、下盖板以及销栓构成。本发明有效解决了可恢复性阻尼器耗能效率低，只能对单一频段的扭转振动起到阻尼作用的问题。本发明采SMA束和杠杆结构，将较小的扭转位移放大，使其耗能效率显著提升；传力机制明确、合理，质量块发生的扭转运动有效地转换成SMA束的拉伸；能够在振动过后自行复位，整体结构呈中心对称，能有效减少偏心距对结构产生的影响；设计合理，结构简单，成本低廉，安装便捷，可以成排、成组地应用于建筑结构。
