目的 为了简化复杂缓冲包装系统设计，拟建立质量主体-EPS泡沫-瓦楞纸板有限元模型。方法 利用EPS泡沫宏观等效可压缩本构模型，同时采用瓦楞纸板薄壁壳结构，对复杂缓冲系统进行有限元计算。结果 得到了符合实际的层状缓冲结构的变形及质量主体的加速度脉冲。结论 该方法丰富了包装动力学的缓冲包装结构设计方法。

The work aims to propose to establish the finite element model for the mass-EPS foam-corrugated board, in order to simplify the design of the complicated cushion packaging system. The constitutive model could be compressed with the macroscopically equivalent EPS foam, and the finite element calculation of the complicated cushioning system was done with the thin-walled shell structure of the corrugated board. The deformation of the laminated cushion structure that met the physical situation and the acceleration pulse of the mass were obtained. Such method enriches the method used to design the cushion packaging structure based on the packaging dynamics.
