Mechanical Properties Analysis on Honeycomb Sandwich Structure Considering Flexural Rigidity of Face Sheets

Abstract

Based on the honeycomb sandwich structure on the supported plates of a satellite antenna, the bending effect of the honeycomb sandwich structure is analyzed with analytical method and finite element method (FEM) to design and verify the models established in the paper. Then, the analytical method without/with considering the flexural rigidity effect of the face sheets is solved. And the equivalent model of the honeycomb sandwich structure is constructed for valuating analysis. Then the three different models are analyzed with finite element method. The results show that, the flexural rigidity of face sheets can affect the bending of the structure when the thickness cant be ignored. Compared to the reality model, the bending results of the equivalent model are more conservative. Its significant in the engineering practice for the honeycomb sandwich structures.
