摘要
基于压电降噪理论,采用COMSOL软件,开展了加筋板结构的减振降噪研究。通过在加筋板上粘贴不同数量的压电片,以及在加筋板不同位置上粘贴压电片,分析加筋板的减振降噪效果,从而进一步地给出了压电片布局优化方案。
In this paper, the vibration and noise reduction of stiffened plat is researched through the COMSOL software, based on the theory of noise reduction of piezoelectric. Different numbers of piezoelectric and different pasting locations are analyzed and compared in the manuscript. Then, the layout optimization of the piezoelectric is given.
