摘要: 为了改善传统蜂窝夹层板结构的吸声特性，提出了一种负泊松比内凹六边形蜂窝夹层板结构，该结构上面板为微穿孔板，夹芯层为负泊松比内凹六边形蜂窝，其由19个具有内延伸管的单元腔体谐振器构成。采用COMSOL仿真软件对负泊松比内凹六边形蜂窝夹层板结构在500~950 Hz频率范围内进行吸声系数的计算，并运用B&K驻波管测量系统对仿真结果的有效性进行了验证。在保持负泊松比内凹六边形蜂窝胞元结构不变的前提下，研究了胞元参数对蜂窝夹层板结构吸声系数的影响，研究结果表明：当胞元倾角增大、内延伸管孔隙率减小、腔体壁厚减小时，结构的吸声性能增强；此外，腔体深度的增加和内延伸管管长的增加都会导致共振频率向更低频方向移动，其中腔体深度的改变更明显。在500~950 Hz频率范围内，该结构比传统蜂窝夹层板结构的平均吸声系数提升了5.64%，表明负泊松比内凹六边形蜂窝夹层板结构在低频范围内具有更优的吸声性能。Abstract: In order to improve the sound absorption characteristics of the traditional honeycomb sandwich panel structure, a negative Poisson's ratio concave hexagonal honeycomb sandwich panel structure was proposed, the upper panel of the structure was a micro-perforated plate, and the sandwich layer was a negative Poisson's ratio concave hexagonal honeycomb, which was composed of 19 units cavity resonators with internal extension tubes. The sound absorption coefficient of the concave hexagonal honeycomb sandwich plate structure in the frequency range of 500-950 Hz was calculated by COMSOL simulation software, and the validity of the simulation results was verified by the B&K standing wave tube measurement system. Under the premise of keeping the structure of negative Poisson's ratio concave hexagonal honeycomb cell unchanged, the influence of cell parameters on the sound absorption coefficient of honeycomb sandwich plate structure was studied. The results show that when the cell inclination angle increases, the porosity of the inner extension tube decreases, and the wall thickness of the cavity decreases, the sound absorption performance of the structure is enhanced. In addition, the increase of cavity depth and the increase of inner extension tube length will lead to the resonance frequency moving to lower frequencies, and the change of cavity depth is more obvious. In the frequency range of 500-950 Hz, the average sound absorption coefficient of the structure is increased by 5.64% compared with the traditional honeycomb sandwich panel structure, indicating that the negative Poisson's ratio has better sound absorption performance in the low frequency range than the traditional honeycomb sandwich panel structure.
