摘要
本文利用振型迭加法,从Winkler粘弹地基上粘弹薄板的动力学方程出发,板和地基材料是用广义Maxwell模型表示的三单元线粘弹性体,直接导出了动挠度在时间域中的解析表达式。最后结合Laplace数值反演技术,给出了算例和结果讨论。从而在理论上探讨了粘弹板——地系统的动力性态,揭示了其动力学行为。
n this paper, the Eigenfunction expansions is used to obtain accurate solution for the vibration of viscoelastic circular plate rested on the winkler viscoelastic foundation,the solution is based on a linearly viscoelastic material represented by a three-element model of the generalized Maxwell model with Laplace transform techniques. At last, we have discussed some properties of viscoelastic plate-foundation and the pavement structures.
