Multi-energy-consumption damper
The invention relates to a multi-energy-consumption damper which comprises a damper shell, a damper box body arranged in the damper shell in a sliding mode due to external vibration, an eddy current vibration reduction energy consumption assembly, a particle damping assembly and a shape memory yield energy consumption assembly, wherein the eddy current vibration reduction energy consumption assembly, the particle damping assembly and the shape memory yield energy consumption assembly are arranged in the damper shell. Compared with the prior art, the particle damper has various energy dissipation forms, when a small earthquake occurs, the particle damper box slides left and right in the damper shell, and damping force is generated through friction collision among particles, energy dissipation of the energy dissipation springs, magnetic induction lines cut by the sliding plates and the conductor rods; when a large earthquake occurs, the relative displacement in the structure is large, the controllable buckles on the connecting plates clamp the end plates and drive the SMA metal yield energy dissipation devices to conduct yield energy dissipation, and a large amount of energy generated by the earthquake is consumed. And earthquakes with different intensities can be effectively dealt with.
本发明涉及一种多重耗能阻尼器，包括阻尼器外壳、因外界振动而滑动设于阻尼器外壳内的阻尼器箱体，以及设于阻尼器外壳内的电涡流减振耗能组件、颗粒阻尼组件和形状记忆屈服耗能组件。与现有技术相比，本发明的耗能形式多样，小震时，颗粒阻尼器箱体在阻尼器外壳内左右滑动，通过颗粒之间的摩擦碰撞以及耗能弹簧耗能，滑板和导体棒切割磁感线，产生阻尼力；大震时，结构内部相对位移较大，连接板上的可控卡扣卡住端板并带动SMA金属屈服耗能装置进行屈服耗能，大量消耗地震产生的能量。能有效应对不同强度的地震。
