Anti-collision energy absorption device based on bionic structure
The invention discloses an anti-collision energy absorption device based on a bionic structure, and relates to the field of rail transit vibration reduction and energy consumption. Comprising a top plate and a bottom plate, a plurality of phononic crystal unit assemblies arranged between the top plate and the bottom plate comprise upper plates and lower plates, rubber corrugated pipes are arranged between the upper plates and the lower plates, vertical hollow pipe springs are arranged in the rubber corrugated pipes, and the lower plates of the phononic crystal unit assemblies at the bottom are fixedly connected with the lower surface of the top plate. The phononic crystal unit assemblies are fixedly connected with one another; a plurality of concentric annular grooves are formed in the upper plate and the lower plate of each phononic crystal unit assembly, and a plurality of steel balls are arranged in each track; second through holes are formed in the ends, close to each other, of the lower plate and the upper plate. By adding an anti-collision energy-absorbing effective structure of a bionic moso bamboo wall vascular bundle honeycomb structure and a tree multi-layer concentric ring structure and combining the local resonance theory of the photonic crystal unit, the damping effect on the structure can be better.
本发明公开了一种基于仿生结构的防撞吸能装置，涉及轨道交通减振耗能领域。包括顶板和底板，顶板和底板之间设置的若干声子晶体单元组件包含上板和下板，上板、下板之间设置有橡胶波纹管，橡胶波纹管内设置有竖直的空心管弹簧，底部的声子晶体单元组件的下板与顶板下表面固定连接，每个声子晶体单元组件之间固定连接；每个声子晶体单元组件的上板和下板内设有若干的同心环形槽，每个轨道内设置有若干钢球；下板和上板相互靠近的一端开设有第二通孔。本发明通过加入仿生毛竹壁维管束蜂窝结构以及树木多层同心环结构的防撞吸能有效构造，再结合声子晶体单元局域共振理论能够实现结构上的减振效果更佳。
