摘　　要：对截面为六边形的薄壁吸能盒引入折纸图案,形成折纸结构。通过ABAQUS软件对铝制结构、碳纤维复合材料(CFRP)结构以及CFRP/AL混合结构进行准静态压缩仿真模拟,分析不同组成组分对吸能盒性能的影响。对于CFRP/AL混合结构进行不同的铺层角度设计,并运用子程序进行模拟仿真,研究不同铺层角度对CFRP/AL混合结构耐撞性能的影响。通过对不同组成组分的吸能盒研究发现,CFRP/AL混合结构的吸能效果远远大于铝制结构、CFRP结构,而且对于不同铺层角度下的CFRP/AL混合结构,表现性能较好的是AL-1-COM-30,其吸能量提升91.48%,比吸能提升24.03%,压缩效率提升43.41%。The thin-wall energy absorbing box with hexagonal section is introduced into the paper folding pattern to form the paper folding structure. The quasi-static compression simulation of aluminum structure, carbon fiber composite material(CFRP) structure and CFRP/AL hybrid structure was carried out by ABAQUS software, and the influence of different components on the performance of the energy absorption box was analyzed. Different layering angles were designed for the CFRP/AL hybrid structure, and the subroutine was used for simulation. The influence of different layering angles on crashworthiness of CFRP/AL hybrid structures was studied. It can be seen from the research and analysis that the energy absorption effect of CFRP/AL hybrid structure is far greater than that of aluminum structure and CFRP structure through the study of energy absorption boxes of different components. Moreover, AL-1-COM-30 is the best CFRP/AL hybrid structure with different lay-up angles, and its energy absorption is increased by 91.48%. Specific energy absorption increased by 24.03% and compression efficiency increased by 43.41%.
