Composite vibration isolation superstructure with photonic crystal characteristics
The invention discloses a composite vibration isolation superstructure with photonic crystal characteristics. The composite vibration isolation superstructure comprises an upper sandwich plate, a lower sandwich plate and a filling metamaterial located between the upper sandwich plate and the lower sandwich plate. The filling metamaterial is formed by arranging unit cell elements with auxetic characteristics through space continuation; the shapes of the unit cell elements comprise concave hexagons, double arrows, stars and other polygons with tensile expansion characteristics; and the upper sandwich plate and/or the lower sandwich plate are/is provided with periodically or quasi-periodically distributed convex body oscillators or embedded scatterers. Control over low-frequency elastic waves and vibration is formed by changing the sizes, the arrangement rules and the arrangement positions in the sandwich plate of the filled metamaterial, the embedded scatterer or the protrusion oscillator with the auxetic characteristic. The vibration isolation superstructure can effectively reduce vibration transmission under low frequency, has high designability, and can be designed according to actual engineering requirements, so that vibration in a specific frequency range cannot be transmitted in the superstructure.
本发明公开了一种具有声子晶体特性复合隔振超结构，该复合隔振超结构包括上夹层板、下夹层板，以及位于上夹层板和下夹层板之间的填充超材料；填充超材料由具有拉胀特性单胞元通过空间延拓布置形成；单胞元形状有内凹六边形、双箭头形、星形及其它具有拉伸膨胀特性多边形；上夹层板和/或下夹层板上布置周期性或拟周期性分布的凸起体振子或嵌入散射体。通过改变具有拉胀特性填充超材料、嵌入散射体或凸起体振子的尺寸、排列规律与在夹层板中的布置位置，形成对低频弹性波和振动的控制。该隔振超结构可以有效降低较低频率下的振动传递，并具有高度的可设计性，能够根据工程实际需要进行设计，使得特定频率范围内的振动在该超结构中不能传播。
