| 摘 要： | 通过横向刚度等效的原则,将金字塔形栅格转变成连续化模型,并通过其刚度常数的推导,使其转变成均匀夹层板,应用Reissner夹层板理论,得到其弹性小挠度下的基本方程,并就简支板为例,得到其解析解,通过与有限元分析进行比较,两者结果吻合良好。

| Abstract: | A sandwich panel with pyramidal truss cores was introduced and transformed into continuum model by means of the equivalent transverse shear stiffness.Its elastic stiffness constants were derived,and then the sandwich panel was idealized as a sandwich panel with uniform cores,and the basic equation was obtained with Reissner sandwich panel theory.The closed-form solution of a simple supported sandwich panel was calculated,and agree well with 3D finite element analysis. |
