Paper deals with an investigation of the dynamic behavior of aluminium honeycomb sandwich panels. The presented study is based on numerical modal analysis where the free vibrations of nine panels are analyzed in order to examine the influence of geometric parameters, such as thickness and height of the core, on their modal parameters. The analyzed panels have a rectangular shape and consist of two aluminum alloy face sheets of thickness 1 mm and hexagonal aluminum honeycomb core, of which height and wall thickness are varying. Additionally, the modal parameters of one single core were analyzed in dependence of wall thickness. The all FEM models were built and the simulations were executed in Abaqus/CAE. The results (natural frequencies and mode shapes) are processed in tabular and graphical form.
