摘　　要：结构轻量化是航空航天、车辆、船舶等领域发展的永恒主题,蜂窝铝夹芯板是轻量化结构中的重要组成部分。该文建立了蜂窝铝夹芯板三点弯曲有限元模型,通过三点弯曲有限元仿真分析来研究蜂窝铝夹芯板结构的力学性能;同时分析了不同面板厚度和不同芯层厚度对结构极限载荷的影响。结果表明,蜂窝铝夹芯板结构的极限承载能力与面板厚度和芯层厚度均呈现正相关关系,且芯层厚度的变化对极限载荷的影响较大。所得研究结果和结论为蜂窝铝夹芯板结构的工程应用提供参考依据。Structural lightweight design is an eternal theme in the development of aerospace,automotive,marine and other fields,and honeycomb aluminum sandwich panels are important component of lightweight structures.In this paper,a finite element model of three-point bending of honeycomb aluminum sandwich panels was established.Through the three-point bending finite element simulation analysis,the mechanical properties of honeycomb aluminum sandwich panel structures were studied.Influences of different panel thicknesses and different core layer thicknesses on the structural ultimate load were analyzed.The results show that the ultimate load-bearing capacity of honeycomb aluminum sandwich panel structures is positively correlated with both panel thickness and core layer thickness,and the change in core layer thickness has a greater impact on the ultimate load.The research results and conclusions obtained in this article provide a reference for the engineering application of honeycomb aluminum sandwich panel structures.
