Abstract

Abstract: Based on the knowledge of material mechanics and elastic mechanics, the theoretical calculation formula of bending stiffness of honeycomb core filled with foamed rubber is derived in this paper. The rationality and feasibility of the theoretical formula are verified by finite element analysis of three-point bending model of honeycomb sandwich structure with or without foamed rubber. At the same time, the relative error between the bending stiffness value of finite element analysis and the theoretical value is controlled within 10%, which makes the calculation formula of theoretical value of filled foamed rubber honeycomb core have certain reference significance and application value.
