Experimental Research of Lamb Wave Tuning in Model Control
调谐兰姆波在模态控制中的实验研究

Lamb wave mode tuning refers to a single-mode Lamb wave testing method via frequency selection under the condition of piezoelectric transducer with certain size. The excitation and control of single-mode Lamb wave was implemented by zuthors based on the theory of Lamb wave tuning. At the same time, the effect of adhesive property and bonding position on transducer on the Lamb wave tuning controlling was experimentally studied. Results show that for different kinds of adhesive, after solidified, the stiffer the adhesive layer is, the better coherence between the experimental and the theoretical is. While for the same adhesive, the bonding at the edge of piezoelectric transducer may produce certain effect on lamb wave mode tuning due to the asymmetric mode stress amplitude increasing.
