| 摘 要： | 约束阻尼层结构是一类利用阻尼层的剪切效应达到减振目的的结构。基于这一原理，本文分析了约束阻尼层板的振动。引入的位移模式中，考虑了附加部分对原结构运动的相对性和阻尼层的横向剪切效应，据此推导了约束阻尼层板的运动方程和边界条件。最后分析了简支矩形板的固有振动，讨论其振动特点。

| Abstract: | Structures added to constrained damping layer are a sort of ones which utilize transverse shear effect of damping layer in order to attain passive control. Based on this principle, this paper deals with the vibration of the plate attached to the constrained damping layer. In the displacement modeling, the transverse shear effect of the attachment on the plate structure is considered, and its displacement is treated as the composition of the base movement and its relative motion to the base. Then, the vibration equation and the boundary conditions are given. Through the natural vibration analysis of a simply supported plate attached to the constrained viscoelastic damping layer, the interaction among the axial vibration, the transverse shear vibration and the bending vibration is discussed. |
