lor of the year摘要：Bumper performance under low-speed impacts and pedestrian-to-vehicle impacts are regulated in the United States by Regulation Part 581 and ECE 127/GTR 9, respectively. The regulations posss a contradictory t of requirements. An ideal bumper structure should be stiff for the former sc

Several energyabsorbing structures capable of passively adapting their mechanical respons were investigated using finite element modelling with complementary validation tests. The preferred structure consisted of a rectangular array of trapezoidal cells which buckle under single-cell impacts while resisting lateral deformation and increasing the structural stiffness under large-area impacts. A geometric study of this dissipater demonstrated the potential to increa total energy 春望原文及翻译
