摘要
提出边界粘弹性支承对矩形板强迫振动响应影响的分析方法。该方法基于阻尼复模态分析 ,利用阻尼复模态的正交性 ,导出了板的完全解耦的模态方程 ;通过算例研究和讨论了粘弹性边界支承对板的振动响应的影响。
In the paper a method for analysis of the effects of viscoelastic boundary supports on the forced vibration of a rectangular plate is proposed. The method is based on damped complex modes analysis method. The solution of vibration response is expressed in terms of a product of the beam solutions under the same boundary conditions. Using the damped complex modes of the beams, the modal equation of the plate motion becomes completely uncoupled. Effects of the viscoelastic boundary supports on the vibration response of the vibrating plate are discussed by an example.
