Self-resetting quasi-zero stiffness shape memory alloy vibration isolator
The invention discloses a self-resetting quasi-zero stiffness shape memory alloy vibration isolator. The self-resetting quasi-zero stiffness shape memory alloy vibration isolator comprises a horizontal vibration isolation ring, an upper support, a lower support, an upper sliding block and a lower sliding block. The lower support is located in the upper support, and the horizontal vibration isolation ring is located on the upper plane of the bottom in the lower support and located between the side wall of the lower support and the side wall of the upper support. The lower sliding block is located on the upper plane of the bottom inside the lower support and is in sliding connection with the lower support, the upper sliding block is in sliding connection with the upper part of the lower sliding block, and the upper support is in sliding connection with the upper face of the upper sliding block. The horizontal shock insulation ring is a shape memory alloy rubber horizontal shock insulation ring, the upper plane of the bottom inside the lower support is zero in curvature, and the lower sliding block is tightly attached to the upper plane of the bottom of the interior of the lower support. Transverse seismic oscillation can be effectively isolated, collision between a structure subjected to seismic isolation and a seismic isolation groove retaining wall or the adjacent structure is reduced, and the self-resetting quasi-zero stiffness shape memory alloy vibration isolator has the advantages of being small in rigidity, low in cost and capable of eliminating residual displacement.
本发明公开了一种自复位准零刚度形状记忆合金隔震器，包括：水平隔震环，上、下支座、上、下滑块，下支座位于上支座内部，水平隔震环位于下支座的内部的底部上平面上，并且位于下支座的侧壁与上支座的侧壁之间，下滑块位于下支座的内部的底部上平面上，两者滑动连接，下滑块的上部滑动连接有上滑块，上滑块的上面滑动连接有上支座，所述的水平隔震环为形状记忆合金橡胶水平隔震环，下支座的内部的底部上平面为零曲率，下滑块与下支座的内部的底部上平面紧密贴合。本发明能有效隔离横向地震动，减少被隔震的结构与隔震沟挡土墙或者相邻构造物之间的碰撞，具有刚度小，成本低，可以消除残余位移的优点。
