Abstract: The structural design and vibration damping characteristics of the CFRP plate structure embedded with acoustic black holes were studied. Firstly, the influence of several common carbon fiber layup angles on the vibration damping characteristics of CFRP plate structure was explored, and then the energy focusing effect of ABH was verified by finite element software, and the influence of different shapes of ABH on the vibration damping characteristics of CFRP plate was explored through harmonic response analysis. The results show that ABH can effectively reduce the vibration of CFRP board and improve the vibration damping performance of CFRP board.

摘要： 碳纤维增强复合材料板（CFRP）以其高比刚度、比强度特性而在航空航天航海等领域得到广泛重视。本文面向航天敏感载荷的高隔振指标需求，提出以内嵌声黑洞（Acoustic Black Hole，ABH）阵列的CFRP板为基础进行敏感载荷隔振装置设计的思路，重点进行了内嵌声黑洞的CFRP板结构设计以及不同组合下的减振特性研究。首先通过探究几种典型的碳纤维铺层角度对CFRP板结构减振特性的影响规律，确定了最佳的铺层角度。随后通过内嵌声黑洞阵列，借助有限元分析法对ABH的能量聚焦效应进行了验证，进而分析了附加不同阻尼材料，不同结构形状的ABH对CFRP板减振特性的影响规律，确定了最佳的组合减振方案。研究结果表明：嵌入式声黑洞能够有效降低CFRP板的振动响应，进一步提升CFRP板的减振性能。
