Analytical and experimental study on honeycomb sandwich plates reinforced by ring beam of satellites

Abstract The equivalent parameters of hexagon aluminum honeycombs are work out with the theories sandwich plates in this paper. honeycomb plate reinforced by ring beam applied static load is simulated finite element model plates, which validated test. research results show that numerical calculation error less than 10% compared test results, acceptable for an engineering project, and mechanical behavior can be described detail. Thus, method parameter proved to effective design analysis plates. influence elasticity modulus shear reflected exactly from figured assembly clearance accuracy have a significant obvious especially at lower level.
