| 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。 |

| Abstract: |
| 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 considerably decrease in compression strength of the box. The purpose was to provide reference for structural design of ventilation holes of fruit & vegetable preservation packaging box. |
