Wave resistance block vibration isolation barrier and design method
The vibration isolation barrier comprises a barrier body formed by continuously arranging a plurality of unit cell units, the barrier body is located on the side where vibration propagation of moving loads is obstructed, and the length direction of arrangement and extension of the barrier body is consistent with the moving direction of the moving loads; each unit cell unit sequentially comprises a base body, a wrapping layer and a core body from outside to inside and extends in the direction perpendicular to the moving direction of the moving load. According to the method, the influence of geometric parameters and material parameters of the periodic wave stop block continuous barrier on the complete band gap is researched, the corresponding parameters of the periodic wave stop block continuous barrier can be adjusted according to the vibration wave frequency range, the target vibration isolation frequency is made to be within the complete band gap, and therefore the better vibration reduction effect is obtained; and a reference is provided for the design of the periodic wave resistance block continuous barrier in practical engineering.
本发明公开了一种隔振屏障波阻块隔振屏障，其包括多个单胞单元连续排列的屏障主体，所述屏障主体位于阻隔移动载荷振动传播的一侧，所述屏障主体排列延伸的长度方向与移动载荷移动方向一致；所述单胞单元从外到内依次为基体、包裹层和芯体，并在与移动载荷移动方向垂直的方向上延伸。本发明通过研究周期性波阻块连续屏障的几何参数和材料参数对完全带隙的影响，可根据振动波频率范围，调整相应的周期性波阻块连续屏障的参数，使目标隔振频率处于该完全带隙内，从而获得更好的减振效果，为实际工程周期性波阻块连续屏障设计提供参考。
