| 摘 要： | 研究置于弹性地基上受到面向预加荷载的对称正交铺设层合板在受到冲击荷载作用时的动力响应，根据高阶剪切变形理论推导出由位移表示的运动方程，用模态叠加法解得振动频率及动力响应，把所得的结果与一阶剪切变形理论做了比较，并讨论了材料、几何参数、地基刚度系数对动力响应的影响。

| Abstract: | A forced vibration for simply supported symmetric cross ply rectangular laminate plates subjected to transient loading combined with initial in plane loads on elastic foundations was investigated. Based on the higher order shear deformation plate theory, the equations of motion expressed by five displacements were deduced. Using the Navier solution method,the vibration frequencies and dynamic response were obtained. The results were compared with those of the first order shear deformation plate theory,and the effects of material and geometric parameters and foundation stiffness on the forced vibratrion were discussed. |
