| Objective To study the simulation design evaluation method for the beverage packaging. Methods The Qoo beverage 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 requirement from standpoint of engineering through the comparison of the numerical simulation results with those of lab tests: deviation 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. |
