以金属薄壁构件为例,研究其薄壁构件沿轴向压缩的历程,在给出薄壁构件的材料模型和有限元模型之后,用碰撞大变形有限元软件PAM-CRASH进行仿真,并对薄壁构件的截面对能量的吸收情况进行了分析,对正方形截面的单元胞和多元胞薄壁结构进行了吸能仿真分析,并对薄壁构件这种能量吸收结构提出建议. Taking the metal thin-walled member as an example, the process of axial compression of the thin-walled member was studied. After the material model and the finite element model of the thin-walled member were given, the finite element simulation software PAM-CRASH was used to simulate the thin- The energy absorption of the thin-walled members was analyzed, and the energy absorption simulation of the unit cells and the multi-cell thin-walled structures with square cross-section was carried out. The energy absorption structure of the thin-walled members was also proposed.
