Liquid Container Drop Impact Computer Stress Simulation

This paper researches the stress distribution of the liquid-storaged containers in avariety of dropping conditions based on kinetic theory of the packaging andpackaging engineering concepts using computer simulation technology. Throughresearch and document retrieval it briefly discusses product packaging concept, thehistorical evolution of the packaging ,the industrial development, vessel structuraldesign in packaging engineering and the dropping impact theory in environmentcirculation. The main achievements of this paper reflect on getting the stress andstress-time law under various conditions via the software of ANSYS.Throughdesigning the effective process, We have done the stress simulation analysis duringthe dropping impact of the glass beer bottles. The first definition of "liquid-inducedstress multiplier factorα" in the dynamic packaging field is of an importantsignificance to understand the impact which is led by the liquid packaging products.In the latter part of the paper, the author expands to three aspects: 1. Simulatethe real flow conditions,lead the function of the corrugated board to the stress analysisof the container.In the same typical conditions, we acquire a series of achievements; 2.analyse the relation between structure and intensity of the container,design structuralOptimization of the beer bottles by stress calculation, it has certain value; 3. analysethe fluid-structure coupling and the modal analysis which both are mature and notdetailed researched in the direction of packaging engineering. preliminarycalculation shows that this is one worthy of further research.
