摘要 摘 要 蜂窝纸板的优点是质轻、承重大等;瓦楞纸板的优点是厚度小、工业 化程度高等。然而,蜂窝纸板和瓦楞纸板都各有缺点。蜂窝/瓦楞复合结构 同时具有蜂窝纸板和瓦楞纸板两者优点,将瓦楞纸板和蜂窝纸板联用，可 以发挥瓦楞纸板和蜂窝纸板的优势，其复合纸板的侧压强度和平压强度均 可以提高。本文的意义在于通过对瓦楞一蜂窝复合结构的压缩吸能特性的 分析对以后这方面的研究和复合结构在实际生活中的应用提供了帮助。 针对瓦楞一蜂窝复合结构在运输包装应用中的静态压缩特性，本文 理论分析了正弦瓦楞一六边蜂窝复合结构的压缩吸能性能。 首先，根据瓦楞一蜂窝复合结构纸板的夹层板结构特征，采用夹层 板理论和弹性力学，对瓦楞一蜂窝复介结构纸板进行静态压缩特性分析， 推导瓦楞一蜂窝复介结构纸板的微分方程，得到其挠度的计算表达式，从 而得出应力一应变关系。 其次，分析复合夹层结构的压缩模式，变形模式。 最后，根据压缩模式，变形模式和压缩吸能原理分析正弦瓦楞一六 边蜂窝复合结构的压缩吸能特性。 关键词 ：正弦瓦楞,六边蜂窝,压缩，吸能 Abstract Abstract The advantages of honeycomb cardboard are light,large bearing capacity, and so on. And the advantages of corrugated cardboard are low thickness, high manufacturing level, and so on. However ,the honeycomb cardboard and corrugated cardboard both have their own shortcomings .Then to explore a new type of material that can make full use of the properties of the two materials is needed. Meanwhile, the advantages of honeycomb cardboard and corrugated cardboard are both existing in honeycomb/corrugated composite cardboard. The significance of this paper is based on a corrugated, the analysis of the compression properties of honeycomb composite structure for future research in this field and composite structure applied in the practical life provides the help. Against a honeycomb composite structures in transport packaging corrugated application the static compression feature, in this paper, theoretical analysis of compression on the sinusoidal corrugated - hexagonal honeycomb composite structure can absorption performance. First of all, according to a corrugated sandwich plate structure characteristics of honeycomb
