Metal composite damper and device
The invention provides a metal composite damper and device, the metal composite damper comprises two constraint plates and a composite viscoelastic layer arranged between the two constraint plates, a plurality of lead cores are arranged between the two constraint plates and the composite viscoelastic layer, and a limiting assembly is arranged between the two constraint plates. Under the condition of shear displacement, through plastic deformation of the lead core and shear hysteresis deformation energy consumption of the composite viscoelastic layer, the two restraint plates generate shear displacement towards two opposite directions in the shear displacement direction, and large initial rigidity and high damping can be provided; the damper has good resilience and moderate damping when stress is terminated, the energy consumption effect of the damper is enhanced, the stability of the whole structure provided with the damper is better guaranteed, the damper has good fatigue resistance under the action of long-term wind load, shear hysteresis deformation can be generated under small displacement for energy consumption, and the energy consumption of the whole structure is reduced. The energy consumption effect is good, and the safety of a main structure can be guaranteed.
本发明提供了一种金属复合阻尼器及装置，包括两块约束板以及设置在两块约束板之间的复合粘弹性层，两块约束板与复合粘弹性层之间设有若干铅芯，两块约束板之间设有限位组件。本发明在发生剪切位移的情况下，通过铅芯的塑性变形和复合粘弹性层的剪切滞回变形耗能，在剪切位移方向上两个约束板向相对的两个方向发生剪切位移，能提供较大的初始刚度和较高的阻尼，在受力终止时具有较好的回复性和适度的阻尼，增强阻尼器自身的耗能效果，更好的保证安装有该阻尼器的整体结构的稳定性，在长期的风荷载的作用下具有较好的耐疲劳性能，能在很小的位移下就产生剪切滞回变形进行耗能，耗能效果好，能保证主体结构的安全。
