Viscous damping module unit with variable damping and self-resetting characteristics
The invention discloses a viscous damping module unit with variable damping and self-resetting characteristics, which integrates a self-resetting technology and a shear viscous damping shock absorption technology and introduces variable viscous damping characteristics. A conventional clearance type viscous damping wall can reduce dynamic response through shear energy consumption of a viscous damping medium under high-frequency dynamic excitation; the self-resetting technology can reduce the residual displacement of the structure in a wide load frequency domain, and ensures the automatic and rapid recovery capability of the structure after the uncertain earthquake action. A plurality of viscous damping module units can be connected in parallel or in series in the same direction to enhance energy consumption or deformation capacity, and a plurality of viscous damping module units can be connected in series in two directions to realize two-way shock absorption and energy consumption, so that the viscous damping module units are more advanced in structural design, the rigidity and damping of the viscous damping module units can be adaptively changed according to a preset control target, and the performance of the viscous damping module units is improved. Cooperative damping control requirements on cost effectiveness, bearing capacity, energy dissipation capacity, reset capacity, comfort and the like can be met, and the damping device has a wide application prospect.
本发明公开了一种具有变阻尼和自复位特性的黏滞阻尼模块单元，融合了自复位技术和剪切黏滞阻尼减震技术，并引入了变黏滞阻尼特性。常规间隙式黏滞阻尼墙能在高频动力激励下通过黏滞阻尼介质的剪切耗能而降低动态响应；自复位技术可以在较宽荷载频域内降低结构的残余位移，确保其在不确定性地震作用后自动快速恢复能力。多个黏滞阻尼模块单元可同向并联或串联增强耗能或变形能力，也可将多个黏滞阻尼模块单元双向串联可实现双向减震耗能，因此，该黏滞阻尼模块单元在构造设计上更为先进，其刚度和阻尼可以按照预设控制目标自适应地改变，可实现在成本效益、承载能力、耗能能力、复位能力和舒适度等多方面协同减震控制需求，具有广阔的应用前景。
