金字塔形格栅夹心夹层板的分解刚度法

The application of split rigidity method of sandwich panel with pyramidal truss cores

采用考虑剪切变形的具有3个广义位移的平板弯曲理论进行分析利用分解刚度法对金字塔形格栅夹心夹层板进行了静力分析,给出了简便实用的计算公式,通过与有限元法分析结果的对比,表明了分解刚度法作为一种简化的计算方法,其精度比较高且计算过程大大简化。

Were analyzed by the theory of plate with consideration of shear deformation and three generalized displacements. The static analysis of a sandwich panel with pyramidal truss cores were studied by split rigidity method. The comparison with the results of finite clement method shows that as a simplified method split rigidity method is very accurate, its precision is more accurate and its calculation is more simplified.
