摘要
利用DY-2型冲击试验机对EPE、EPS进行了动态压缩试验,实验中选取对应于缓冲系数最低点的一组试样测量它们每次冲击一分钟后的厚度,并进行弹性变形对比.实验结果表明:在进行动态冲击后,EPE恢复原状的速度快于EPS,EPE的弹性变形率小于EPS,且两组试样均在第三次冲击后达到弹性极限.
Made experiments on EPE and EPS through DY-2 dynamic compression machine,selected a particular set of samples.Survey their thickness every minute after each dynamic impact,compared their elastic deformation.The laboratory result proved that：after dynamic impact,the restoration speed of EPE is faster than that of EPS,EPE′s elastic deformation rate is smaller than EPS′s,Both of them reached their elastic limit after the third impact.
