| 摘 要： | 为了分析层合板受到斜荷载冲击时的响应,基于Kirchhoff经典层合板理论从平衡微分方程出发推导层合板振动的控制微分方程,利用模态叠加原理求解层合板振动控制微分方程得到层合板的位移、速度和加速度的响应.给出算例,分析了冲击力的大小、冲击的角度、板的尺寸等参数对接触面上最大剪应力的影响,并给出了剪应力在接触面上的分布情况.

| Abstract: | The study was present,that on the dynamic response of composite laminated plates under inclined loads impact.Base on Kirchhoff classical composite laminated plated theory,the dynamic control differential equation of the composite laminated plates was established by the equilibrium differential equation.The dynamic response values relate to the structure displacement,speed and acceleration are obtained by using modal superposition methods to solve the dynamic control differential equation of the composite la... |
