摘要
通过建立不同通风孔设计的果蔬保鲜包装箱有限元模型,模拟分析了其应力分布云图,探讨了果蔬保鲜包装箱通风孔设计的主要参数。分析结果表明,长圆形、靠近纸箱中部且对称分布的偶数个通风孔设计,能有效减少应力集中,避免纸箱压缩强度的大幅下降。为实际应用中果蔬保鲜包装箱通风孔结构设计提供参考。
A FE model of fruit ＆ vegetable preservation packaging box with various designs of ventilation holes were established with respect to stress distribution. The principal design parameters of ventilation holes of fruit ＆ vegetable preservation packaging box were discussed. The result showed that the appropriate pattern with oblong-shaped, close to carton middle, even hole number with symmetrical distribution can minimize stress concentration, which avoids consid- erably decrease in compression strength of the box. The purpose was to provide reference for structural design of venti- lation holes of fruit ＆ vegetable preservation packaging box.
