【摘要】 针对一种新型组合蜂窝结构(SCCH)开展研究，该结构将方形管与圆形管进行组合，充分发挥了圆形管的吸能优势和方形管的变形优势。通过试验与有限元仿真，对比了SCCH结构与传统圆形蜂窝结构(CH)在面内压缩的力学性能和不同应变时的变形行为。结果表明，SCCH结构的总吸能为0.198 kJ、平均压缩力为5.50 kN、初始峰值压缩力为6.80 kN、比吸能值为6.22 kJ/kg,均优于CH结构。此外，SCCH结构的比吸能明显高于其他常见的蜂窝结构，具有优异力学性能和吸能性能的SCCH结构，可为设计具有高吸能能力的蜂窝结构提供有益借鉴和设计基础。更多还原

【Abstract】 This study investigates a novel Square-Circular Combined Honeycomb(SCCH) structure, which amalgamates square and circular tubes, capitalizing on the energy absorption superiority of circular tubes and the deformation advantages of square tubes.The mechanical properties and deformation behaviors under in-plane compression of SCCH structure were compared with the traditional Circular Honeycomb(CH) structure at different strains through experimentation and finite element simulation.The results demonstrate that the total energy absorption of the SCCH structure is 0.198 kJ,the mean compression force is 5.50 kN,the peak compression force is 6.80 kN,and the specific energy absorption is 6.22 kJ/kg, all of which outperform the CH structure.Furthermore, the specific energy absorption of the SCCH structure significantly surpasses other common honeycomb structures.The SCCH structure, with its exceptional mechanical and energy absorption properties, provides valuable reference and design basis for designing high-energy absorbing honeycomb structures.更多还原
