摘　　要：本文将金字塔形栅格夹心夹层板假设成均匀夹心夹层板,应用Reissner夹层板理论,对其自振频率以及在简谐荷载下的强迫振动进行了研究,并以简支板为例,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。并把金字塔形栅格夹层板与同质量实体板进行比较,得出金字塔形栅格夹层板具有更好动力性能。A sandwich panel with pyramidal truss cores was assumed as a sandwich panel with uniform cores. Its dynamic problems were studied with Rei.ssner sandwich panel theory. The closed form solution of a simple supported sandwich panel was calculated, and agree well with 3D finite element analysis. The sandwich panel with pyramidal truss cores has better dynamic performance by comparison between sandwich panels with pyramidal truss cores and solid panels with same mass.
