能量吸收结构广泛应用于许多场景中。薄壁构件已大量用于吸收冲击能量。本文提出了一种新颖的，罗恩Resch折纸图案启发的能量吸收结构。通过实验表征和数值模拟研究了该结构的能量吸收特性。结果表明，与传统蜂窝结构相比，蜂窝结构具有多条塑性铰线的能量吸收模式，峰值力降低，有效行程增大。总的来说，罗恩Resch折纸启发的结构和经典的蜂窝结构作为能量吸收结构是非常互补的。
Energy absorption structures are widely used in many scenarios. Thin-walled members have been heavily employed to absorb impact energy. This paper presents a novel, Ron Resch origami pattern inspired energy absorption structure. Experimental characterization and numerical simulations were conducted to study the energy absorption of this structure. The results show a new collapse mode in terms of energy absorption featuring multiple plastic hinge lines, which lead to the peak force reduction and larger effective stroke, as compared with the classical honeycomb structure. Overall, the Ron Resch origami-inspired structure and the classical honeycomb structure are quite complementary as energy absorption structures.
