Three-dimensional lead viscoelastic damper with variable rigidity
The rigidity-variable three-dimensional lead viscoelastic damper comprises lead cores, a laminated viscoelastic body and connecting plates, the connecting plates are fixed to the upper side and the lower side of the laminated viscoelastic body respectively, and the lead cores are arranged in the middles of the connecting plates and the laminated viscoelastic body. The advantages of small deformation energy consumption characteristic and good deformation capacity of the viscoelastic material and stable energy consumption characteristic of the lead core are fully exerted, three-dimensional space energy consumption is achieved through the synergistic effect of the lead core and the viscoelastic material, and three-dimensional energy consumption and space deformation capacity are achieved. Three-dimensional shock absorption and energy consumption can be achieved, energy input into the structure by an earthquake is effectively consumed, and the structure meets the anti-seismic requirement.
本发明提供了一种可变刚度的三维铅黏弹性阻尼器，包括铅芯、叠层黏弹性体和连接板，所述叠层黏弹性体的上下两侧分别固定有所述连接板，所述连接板和所述叠层黏弹性体的中部设有所述铅芯。本发明充分发挥黏弹性材料的小变形耗能特性、良好变形能力与铅芯的稳定耗能特性的优点，利用铅芯与黏弹性材料的协同作用，实现三维空间耗能，具有三维耗能与空间变形能力。能够实现三维减震耗能，将有效消耗地震输入结构的能量，使结构满足抗震要求。
