Evaluation Method of Beverage Packaging Design Based on the Lsdyna971 Explicit Algorithm

目的研究饮料包装的仿真设计评价方法。方法以酷儿饮料包装为研究对象,基于Pro/E 5.0和Hypermesh 10.0软件建立3D模型和有限元动力学仿真模型,然后调用Lsdyna971显示算法程序执行顶部静压和侧面挤压等多工况动力学仿真计算,同时进行相应的实物试验验证。结果数值仿真结果与试验结果的对比分析得出两者的结果偏差不超过15%,能够满足工程学上的设计要求。结论基于Lsdyna971显式算法的虚拟设计评价方法完全适用于饮料包装设计研发,且可大幅缩减实物试验费用和新饮料包装设计周期。

Objective To study the simulation design evaluation method for the beverage packaging. Methods The Qoo bev- erage packaging was selected as the research object, and the 3D and finite element dynamic simulation models were built with softwares Pro/E 5.0 and Hypermesh 10.0, respectively. Then dynamic simulation ＆ calculations with the multiple cases, such as top loading and side extruding were executed via the Lsdyna971 explicit algorithm, and corresponding physical tests were conducted to verify the virtual simulation results. Results All result deviation rates were below 15%, which met the design re- quirement from standpoint of engineering through the comparison of the numerical simulation results with those of lab tests ： de- viation rate 〈 15%. Conclusion The virtual design evaluation method based on the Lsdyna971 explicit algorithm can be well applied to the development of beverage packaging design. It can also dramatically reduce the physical test cost and the design cycle of new beverage packaging.
