Amplified energy dissipation damping extension arm based on hydraulic transmission
The invention discloses an energy dissipation damping extension arm based on hydraulic transmission amplification. The extension arm comprises a core tube, an outer frame column, a hydraulic amplification device, a viscous damper and an extension arm truss. Wherein the upper end of the hydraulic amplification device is hinged to an upper chord of the outrigger truss through a pin shaft, the lower end of the hydraulic amplification device is connected with one end of the viscous damper, and the other end of the viscous damper is connected with a steel corbel fixed to the outer frame column. The working efficiency of the damper is effectively improved through the amplification effect of the liquid amplification device, the small deformation of the main body structure is utilized, the deformation amount and the deformation speed are amplified through the effect of the hydraulic amplification device to excite the damper effect, and therefore external load input energy is consumed in a concentrated mode, and the damage effect of external input on the main body structure is reduced; the structure comfort level and the anti-seismic safety performance are improved, and the method has important practical significance on the development of a super high-rise structure.
本发明公开了一种基于液压传递放大消能阻尼伸臂，其包括：核心筒、外框柱、液压放大装置、粘滞阻尼器以及伸臂桁架；其中，所述液压放大装置的上端通过销轴铰接于所述伸臂桁架的上弦杆，液压放大装置的下端与所述粘滞阻尼器的一端连接，所述粘滞阻尼器的另一端与固定在所述外框柱上的钢牛腿连接。本发明通过液体放大装置的放大作用有效提高了阻尼器的工作效率，利用主体结构较小变形，通过液压放大装置的作用放大变形量与变形速度激发阻尼器作用，从而集中消耗外部荷载输入能量，减小外部输入对主体结构破坏作用，提高结构舒适度及抗震安全性能，对超高层结构发展具有重要实际意义。
