EPE泡沫塑料在多次冲击下的缓冲性能

目的预测并分析多次冲击下EPE缓冲材料的缓冲性能。方法应用应力-能量法得到并分析多次冲击下的缓冲曲线,评价EPE缓冲材料的缓冲性能变化。结果 EPE试样在经受多次冲击后,厚度会减小,缓冲性能会下降。结论在缓冲包装设计中,要充分考虑环境因素,根据物流环境条件适当增加缓冲垫厚度,使产品得到充分防护。

EPE Foam Cushioning Performance under Repeated Dropping Shocks

The work aims to predict and analyze the cushioning performance of EPE cushion material under repeated dropping shocks. Stress-energy method was used to obtain and analyze the cushioning curves under repeated dropping shocks. Then, the change in cushioning performance of EPE cushion material was evaluated. After the EPE samples were subject to multiple dropping shocks, the thickness decreased and the cushioning performance reduced. In the process of designing the cushion packages, the environmental factors should be taken into full consideration. To sufficiently protect the products, the cushion thickness should be added properly according to the conditions of logistics environment.
