Viscoelastic damper with adjustable compressive pre-stress
The invention discloses a viscoelastic damper with adjustable compressive pre-stress, and belongs to the technical field of structural damping. The main body comprises a constraint unit, an energy consumption unit and a connecting unit. The energy consumption unit is made of hydrogel/porous metal composite materials, impedance force with hysteretic characteristics is generated through shear deformation to absorb vibration, and the effect is remarkable. The elastic degree of the belleville spring is controlled through the adjusting bolt to provide different pre-tightening forces, so that the energy dissipation and shock absorption effects of the viscoelastic damper are changed, structural vibration caused by earthquakes and wind vibration can be remarkably reduced, and the viscoelastic damper is more economical. The device is good in damping effect, simple in structure, convenient to install, easy to replace under a large earthquake and suitable for various applications from new building to existing building renovation, and high quality and low cost can be achieved through large-scale production of high-quality industrial products and standardized systems.
本发明公开了一种预压应力可调的黏弹性阻尼器，属于结构减震技术领域。主体包括约束单元、耗能单元以及连接单元。耗能单元选用水凝胶/多孔金属复合材料，由剪切变形产生有滞回特性的阻抗力吸收震动，效果显著。通过调节螺栓来控制碟形弹簧的松紧程度，以提供不同的预紧力，由此改变黏弹性阻尼器的消能减震效果，能显著减小由地震和风振引起的结构振动，更为经济。本发明减震效果好，构造简单，安装方便，大震下易于更换，并且适用于从新建到现有建筑翻新的各种应用，通过大规模生产高质量的工业产品和标准化的系统，可实现高质量和低成本。
