摘　　要：为降低鸡蛋在流通过程中的破损率,基于鸡蛋的流固耦合特性,利用ABAQUS有限元软件对鸡蛋缓冲包装常用的聚苯乙烯泡沫(Expanded Polystyrene,EPS)、可发性聚乙烯(Expandable Polyethylene,EPE)缓冲包装进行跌落冲击力学仿真;并通过强度试验确定鸡蛋的破损强度,为仿真分析提供破损标准。结果表明:同一厚度下EPE的缓冲效果优于EPS,选择缓冲材料厚度EPE≥10mm,EPS≥25mm,可有效避免鸡蛋在跌落冲击过程发生破损。In order to reduce the breakage rate of eggs in circulation,the drop impact simulation of Expanded Polystyrene(EPS)and Expandable Polyethylene(EPE) commonly used in cushioning packaging of eggs were studied based on the fluidstructure coupling model by ABAQUS.Moreover,the strength of eggs was determined by strength test for providing the egg damage standard for simulation analysis.The results showed that the cushioning effect of EPE was better than that of the EPS at the same thickness.The cushioning material thickness of EPE(≥10 mm)and EPS(≥25 mm)could effectively satisfy the requirement avoiding the breakage of eggs.
