基于经典叠层板理论,将铝基蜂窝芯层等效为一正交异性层,等效弹性参数由修正后的Gibson公式得出,对四边固支薄蜂窝夹层板弯曲振动的固有频率进行了理论推导,研究了蜂窝夹层板厚度、芯层板厚度对蜂窝夹层板固有频率的影响。同时利用有限元软件计算了相应参数下的固有频率。计算结果表明,经典叠层板理论可以较准确的计算四边固支蜂窝夹层板的固有频率。 Based on the classical laminate theory, the aluminum honeycomb core is equivalent to an orthotropic layer, and the equivalent elastic parameters are derived from the modified Gibson formula. The natural frequencies of the bending vibration of thin honeycomb sandwich panels Theoretical deduction, the honeycomb sandwich plate thickness, the thickness of the core plate on the honeycomb sandwich plate natural frequency. At the same time, using the finite element software to calculate the corresponding parameters of the natural frequency. The calculation results show that the classical laminated plate theory can calculate the natural frequencies of the honeycomb sandwich panels with four sides more accurately.
