摘　　要：为了研究蜂窝夹层结构受剥离力时面板的变形和蜂窝芯中的应力，对蜂窝夹层梁进行了数学分析和实验验证．将建筑中的弹性地基上梁的理论用于蜂窝夹层结构分析，视面板为弹性地基上的梁，视蜂窝芯为弹性地基，得出了蜂窝夹层结构受剥离力时的面板变形和夹芯中的应力分布的计算公式．通过分析和实验指出，将建筑中的弹性地基上梁的理论用于蜂窝夹层结构分析，具有计算量小、精确度较高和公式直观等优点．This work investigated honeycomb sandwich structure with mathematical analysis and experimental verification in order that the deformation of the face sheet and the stress in the honeycomb core of honeycomb sandwich structure under peeling load can be obtained. The theory of beam on elastic foundation was applied to the sandwich structure. The formula to compute the deformation of the face sheet and the distribution of stress in the core was given for sandwich structure under peeling load based on model in which the core was regarded as elastics foundation and the face sheet beam on the foundation. The conclusion was reached that the method suggested by the work to analyze sandwich structure is feasible, with merits of low quantity of computation, high precision and direct formula.
