附加式声学黑洞梁对平板的振动影响分析
Analysis of the Influence of Additional Acoustic Black Hole Beam on the Vibration of Plate Structures
摘要
Abstract
Acoustic black hole(ABH)possesses broad-frequency and high efficient vibration control capability.The structure of ABH is simple and ABH can be manufactured easily,which is widely used to solve problems of structural vibra-tion and control.While dynamic vibration absorber(DVA)is commonly used equipment for vibration reduction.Although DVAs have good vibration control effects in the low frequency range,their vibration control frequency band is narrow.In this paper,an 1D ABH-DVA was designed based on the principles of ABH and DVA and attached to the primary plate struc-ture as an additional DVA.Due to the rich dynamic characteristics and efficient vibration energy absorption and dissipation ability of the 1D ABH-DVA,it can realize broadband vibration control for the primary plate structure.The dynamic charac-teristics of the plate structure with the additional 1D ABH-DVA were explored,and its suppression effect on the broadband stable vibration peak of the plate was verified.The vibration reduction characteristics of 1D ABH-DVA were analyzed,and the potential mechanism of 1D ABH-DVA for plate vibration control was analyzed.This work has a reference value for fur-ther research on the application of ABHs.关键词
