摘要
本文首先推出了四种粘弹性地基上弹性薄板在时间域上的动力学方程 ,并给出了三元件和 Kelvin粘弹性地基上矩形薄板的固有频率的解析解 ,然后对振动特性进行了分析和比较 。
In this paper,the free vibration equation of elastic foundation plate on viscoelastic foundatons are derived ,and the analytical solutions to the natural frequencies are given for elastic rectangular plates on kelvin and three elements viscoeastic foundations .Their dynamic behaviors are analyzed and compared.Example and conclusions are given in the end.
