| 摘 要： | 为了研究不同质量、不同厚度条件下,发泡聚乙烯的最大加速度-静应力及缓冲系数变化情况,基于有限元法对EPE的缓冲性能进行了分析。结果表明：随着静应力的增加,即随着质量块质量的增加,最大加速度与静应力并不成正比,而是先减小后增加;随着缓冲材料厚度的增加,最大加速度与厚度也不成正比,厚度的增加并不一定能够改善缓冲材料的缓冲性能。

| Abstract: | In order to study the maximum acceleration-static stress curve and cushion coefficient of expanded polyethylene （EPE） under the different quality and different thickness, the cushioning properties of EPE are analyzed based on the finite element method. The results show that with the increase of static stress, the maximum acceleration and static stress are not proportional, but the maximum acceleration first decreases and then rises. With the increasing of thickness, maximum acceleration and the thickness of EPE are not proportional. The cushioning properties of EPE do not be necessarily improved with the increase of thickness. |
