Self-adaptive energy dissipation and shock absorption device
The invention discloses a self-adaptive energy dissipation and shock absorption device, and relates to the technical field of shock absorption devices, the self-adaptive energy dissipation and shock absorption device comprises an I-shaped connecting piece, and the I-shaped connecting piece is slidably sleeved with a mass block and a friction self-resetting energy dissipater; the friction self-resetting energy dissipater comprises a three-layer connecting plate installed on the upper side of the transverse plate and a double-layer connecting plate installed at the bottom of the mass block, a double-layer plate of the double-layer connecting plate is inserted between two plate seams of the three-layer connecting plate, and the inner side of the three-layer connecting plate and the inner side of the double-layer plate are each provided with a plurality of trapezoidal tooth openings meshed with one another. Friction plates are arranged between the two outer sides of the double-layer connecting plate and the third-layer connecting plate, and the third-layer connecting plate, the double-layer connecting plate and the friction plates are connected through elastic connecting assemblies. When the pedestrian overpass is used as a main structure to generate dynamic response, the device can adjust the vertical rigidity of the device according to the response of the main structure of the pedestrian overpass, so that the resonant frequency of the device can be adaptively adjusted within a certain frequency range, and the energy consumption requirement can be met even when a plurality of resonance points appear on the structure.
本发明公开了一种自适应耗能减震装置，涉及减震装置技术领域，包括工字形连接件，工字形连接件上滑动套设有质量块和摩擦自复位耗能器；摩擦自复位耗能器包括安装在横板上侧的三层连接板以及安装在质量块底部的双层连接板，双层连接板的双层板插设于三层连接板的两板缝之间，且三层连接板及双层板内侧均设有若干相互啮合的梯形齿口；双层连接板的两外侧与三层连接板之间均设有摩擦片，三层连接板、双层连接板和摩擦片通过弹性连接组件相连；当人行天桥作为主结构发生动力响应时，本装置能够根据当人行天桥主结构响应调整自身的竖向刚度，使其共振频率能够在一定频率范围自适应地进行调整，即使当结构出现多个共振点时，也能满足耗能要求。
