智能物流环境监测仪包装设计及跌落仿真

Packaging Design and Drop Simulation of Intelligent Logistics Environmental Monitor

目的基于有限元软件对某智能物流环境监测仪进行跌落仿真分析以验证其包装设计的合理性。方法本文根据某智能物流环境监测仪的结构特征和防护要求,以发泡聚乙烯(EPE)为主要缓冲材料设计了一款缓冲包装,利用LSDYNA软件对其进行高度为1.2 m的面、棱、角跌落仿真分析,并进行了跌落试验验证。结果仿真和试验结果均表明,EPE缓冲垫和瓦楞纸箱在产品跌落过程中吸收大部分能量,产品最大应力远小于其失效应力,验证了所设计缓冲包装的合理性,也为其它产品结构及包装设计提供了参考。

Objective Based on the finite element software,the drop simulation analysis of an intelligent logistics environmental monitor was carried out to verify the rationality of its packaging design.According to its structural characteristics and protection requirements,a package with foamed polyethylene(EPE)as the main cushioning material is designed.The surface,edge and angle drop simulation analysis of the height of 1.2m is carried out based on LS-DYNA software,and the drop test is verified.Simulation and test results show that EPE cushion and corrugated box absorb most of the energy in the process of product falling,and the maximum stress of the product is far less than its failure stress,which verifies the rationality of the designed cushion package,and also provides a reference for other product structures and packaging design.
