摘    要:目的研究鸡蛋缓冲包装的结构及缓冲效果。方法利用Ansys/LS-DYNA有限元分析软件,对所设计的缓冲包装结构在0.6 m的跌落高度进行角跌落仿真,得到鸡蛋和包装件在与地面接触瞬间、回弹瞬间及跌落结束瞬间的等效应力云图及危险点的加速度曲线,模拟鸡蛋在流通过程中包装件受到冲击和振动时鸡蛋的应力变化,以检验缓冲包装的缓冲效果。结果在跌落过程中,包装件与地面接触瞬间的等效应力最大,为0.784 MPa,小于瓦楞纸板的极限应力;危险点的最大加速度为59g,小于鸡蛋的脆值60g。结论设计的缓冲包装能够起到很好的缓冲效果,可有效提高鸡蛋运输过程中的安全性。

关 键 词:鸡蛋  缓冲包装  角跌落  有限元分析

Abstract:The work aims to study the cushioning packaging structure and cushioning effect of egg. The designed cushioning packaging structure carried out the angle drop simulation at the drop height of 0.6 m with the Ansys/LS-DYNA finite element analysis software to obtain the equivalent stress nephogram of the egg and package in contact with the ground, at the time of springback and at the end of drop, and the acceleration curve of the dangerous points, to simulate the egg stress change in the course of circulation of the egg when the package was subject to shock and vibration, so as to verify the cushioning effect of the cushioning packaging. The maximum equivalent stress of the contact between the package and the ground was 0.784 MPa, lower than the limit stress of the corrugated paperboard; the maximum acceleration of the dangerous point was 59g, smaller than the crisp value 60g of the egg in the process of dropping. Designed cushioning packaging can give good cushioning effect and effectively improve the safety of egg transport process.
Keywords:egg  cushioning packaging  angle drop  finite element analysis
