基于运输环境的包装系统疲劳损伤分析

目的针对当前物流运输环境,研究产品在运输过程中因受到不同振动与冲击导致的包装系统疲劳损伤情况。方法针对以聚苯乙烯泡沫为缓冲包装材料的包装系统进行运输环境模拟,通过使用有限元分析软件,对运输环境中包装系统受到的随机振动进行仿真,发现包装系统的薄弱部分,针对薄弱部分进行疲劳仿真,最终得出薄弱处的损伤数据。结果仿真结果表明,包装件能够在实际运输过程中对产品起到保护作用,为产品的运输包装方案提供了指导性意见。结论该方法不仅适用于文中的包装系统,对常见家用电器的包装方案均可进行评价。

Fatigue Damage of Packaging System Based on the Transportation Environment

The work aims to study the fatigue damage of packaging system caused by different vibration and impact during product transportation in the current logistics transportation environment. In view of the transportation environment simulation of the packaging system with polystyrene foam as the cushion packaging material, the finite element analysis software was used to simulate the random vibration of the packaging system in the transportation environment, so as to obtain the weak part of the packaging system. The fatigue simulation of the weak part was conducted to obtain its damage data. The simulation results showed that, the package could protect the product in the actual transportation process, and provide guidance for the packaging transportation scheme of the product. The proposed method is not only applicable to the packaging system herein, but also can be used to evaluate the packaging schemes of common household appliances.
