| 摘 要： | 根据伽辽金法,用Matlab/Simulink软件对推导的经典板假设理论、一阶剪切理论蜂窝夹层板运动方程进行了数值仿真。简单算例的计算结果表明两者基本一致。基于一阶剪切理论讨论了蜂窝夹芯泊松比对蜂窝夹层板低阶频率的影响。发现当泊松比接近1时对频率响应有显著的影响。

| Abstract: | According to Galerkin method,the numerical simulation of the equations derived by the classical plate assumption theory and the one order shear deformation theory for forced vibration of a honeycomb core sandwich panel was done within Matlab/Simulink software in this paper.The results of a simple case showed that the two theories were similar.The effect of Poisson ratio of the honeycomb core on the one order natural frequency of the whole panel based on the low order shear deformation theory was discussed.I... |
