利乐砖棱跌落试验仿真研究

对装有液体的利乐砖型包装进行跌落试验,检测包装设计的效果。对于动态加载情况,ABAQUS/Explicit提供先进方法用于连续体非线性结构的动态仿真。通过有限元仿真代替真实的跌落试验,以降低试验成本,提高实验效率。仿真试验得到的结果与真实包装试验结果进行了比对,结果相似。在包装材料出现破损时,剪切应力集中通常出现在发生包装破损同样的地方。随着跌落高度的增大,应力增大,这与实际吻合很好。

Edge Drop Test Simulation of Tetra Brick Carton

Tetra brick cartons containing liquid were tested in the drop test method to evaluate the effect of packaging design.ABAQUS/Explicit was applied in the dynamic simulation.The purpose of the FE simulation of the dynamic drop test procedure was to reduce cost and improve efficiency of test.Comparison was made between real test and simulation results and it showed that the results are similar;shear stress concentrations are usually located in the same areas that cracks appear in the packaging material;stress i...
