Abstract ∵ This paper takes the large-scale array honeycomb stack structure as the research object in order to solve the problems of numerous model features and large-scale numerical calculation caused by its huge overall structure in mechanical performance analysis.The grid independence verification work is first caried out by taking a single honeycomb module as the entry point. On this basis,the “substructure” modeling method is adopted to reasonably divide the overallstructure into multiple substructures, and detailed modeling and analysis are carried out respectively, which can significantly reduce the modeling complexity. At the same time, the "gravity equivalent pressure” simplification modeling method is introduced. By converting gravity into equivalent pressure and applying it to the bottm layer model, the calculation efciency is greatly improved.The upper limit of the actual structure mechanical analysis of the honeycomb stack structure is provided to a certain extent.To further improve the analysis efficiency,the distributed row and distributed column simplification modeling method is adopted,and a detailed comparison of the strength and stiffess variation trends is carried out.Theresults show thatunder the premise offull ensuring the analysis accuracy,this method can accurately provide the lower limit of the actual structure mechanical analysis.These simplified modeling methods,when used in combination,can eficientlyand accurately verifythe mechanical performance of large-scalearray stack structures.
