摘　　要：为研究多胞结构胞元间的粘接条件对结构耗能特性的影响,将碳纤维增强环氧树脂复合材料方管采用环氧树脂胶以不同粘接条件粘接在一起形成多胞结构,并进行了准静态压缩试验,分析了不同粘接条件下多胞结构的压缩破坏模式和耗能特性。研究结果表明:胞元间采用侧面粘接或底部粘接的方法可提高多胞结构的耗能特性;粘接底部比侧面粘接对多胞结构的耗能量和压缩载荷的影响更大;完全粘接试件的平均压缩载荷、耗能量和比吸能均最大。对于三胞结构而言,品字型三胞结构的耗能特性比L型三胞结构耗能特性更优。In order to study the effects of adhesion conditions between cells of multi-cell structures on the energy absorption characteristics of structure,carbon fiber reinforced epoxy resin composite square tubes are bonded together with epoxy resin adhesive under different adhesion conditions to form multi-cell structures.The quasi-static compression tests are carried out,and the compression failure mode and energy absorption character-istics of multi-cell structures under different adhesion conditions are analyzed.The results show that the energy absorption characteristics of multi-cell structures can be improved by using side adhesion or bottom adhesion be-tween cells.The effects of bottom adhesion on the energy absorption and compressive load of multi-cell structures are greater than those of side adhesion.The average compressive load,energy absorption and specific energy ab-sorption of full adhesion specimens are the largest.For tri-cellular structure,the energy absorption characteris-tics of品-shaped tri-cellular structures are better than those of L-shaped tri-cellular structure.
