چكيده فارسي :
The current investigation focuses on design, analysis and dynamic response of the sample of micro-satellite Aluminum
panel structure. Aluminum face sheet sandwich panels have been manufactured and are studied. Modal tests have been performed
with impact hammer equipment. Modal analysis have been done with 2D and 3D numerical models of sample satellite sandwich
panel structure with commercial finite element (FE) code, ABAQUS 6.12.1. There is a good agreement between FE modeling and
analytical stress results; also 6.73 % is the maximum discrepancy between numerical and experimental first 5th modal frequencies,
also comparison between numerical predicted mode shapes and experimental ones implies a very good likeness.
