Abstract: Honeycomb sandwich structure composite with light weight and high specific strength and specific stiffness has been widely used in many fields in recent years. In this paper, the research results at home and abroad are combed and summarized from the aspects of equivalent parameters of honeycomb core and honeycomb equivalent model. The equivalent parameters of honeycomb core layer are classified and discussed from the aspects of theoretical formula derivation, homogenization method and finite element method, and the equivalent models are compared based on sandwich plate theory, honeycomb plate theory, equivalent plate theory and other equivalent methods. Finally, some suggestions on the research direction of the equivalent model of honeycomb sandwich structure are put forward.    

Key words: honeycomb sandwich structure, equivalent parameter, equivalent model, composites
