摘要
目的研究设计的包装结构对高脚杯的缓冲效果。方法建立高脚杯缓冲包装件实体模型,导入Ansys/LS-DYNA中,确定材料的性能参数及边界条件,进行跌落仿真,分析仿真结果。结果根据跌落仿真得到的应力云图,分析在跌落和回弹过程中包装件及内装物的应力变化,通过对最大加速度进行分析表明,设计的缓冲包装结构能够使高脚杯的最大加速度在80g以下。结论设计的缓冲包装满足产品脆值要求,达到了缓冲包装的效果。
This work aimed to study the cushioning effect of the packaging structure designed. A goblet cushion package model was introduced into Ansys/LS-DYNA, the material parameters and boundary conditions were determined, drop simulation was conducted, and the simulation results were analyzed. According to the stress cloud obtained by drop simulation, the stress changes of the package and the contents during the fall and rebound processes were analyzed. Based on the maximum acceleration analysis, the cushion packaging structure designed could keep the maximum acceleration of goblet below 80 g. The cushion packaging designed met the fragility requirement of the product, and reached the cushioning effect.
