Three-dimensional lead viscoelastic damper and preparation method thereof
The invention provides a three-dimensional lead viscoelastic damper and a preparation method thereof, the three-dimensional lead viscoelastic damper structurally comprises a lead core, a viscoelastic body and sealing plates, the sealing plates are arranged on the upper side and the lower side of the viscoelastic body, and the lead core is arranged at the center of the viscoelastic body and the center of the sealing plates. The three-dimensional space energy consumption is realized by utilizing plastic deformation generated after shearing or extrusion yield of lead and shearing and tension-compression hysteresis deformation energy consumption of a viscoelastic material through organic combination of the plastic deformation and the shear and tension-compression hysteresis deformation energy consumption. The advantages of small deformation energy consumption characteristic and good deformation capacity of the viscoelastic body and stable energy consumption characteristic of the lead core are fully exerted, and three-dimensional space energy consumption is achieved through the synergistic effect of the lead core and the viscoelastic body.
本发明提供了一种三维铅黏弹性阻尼器及其制备方法，其结构包括铅芯、黏弹性体和封板，所述黏弹性体的上下两侧设有所述封板，所述黏弹性体和所述封板的中心处设有所述铅芯。本发明利用铅的剪切或挤压屈服后产生塑性变形和黏弹性材料的剪切和拉压滞回变形耗能，利用两者的有机结合实现三维空间耗能。充分发挥黏弹性体的小变形耗能特性、良好变形能力与铅芯的稳定耗能特性的优点，利用铅芯与黏弹性体的协同作用，实现三维空间耗能。
