项目摘要

The Split Hopkinson bar method (SHB) has been widely used for impact tests of compression. However, the SHB method for low mechanical impedance materials such as rubber or soft plastics has not been established, because that their deformation strengths are extremely small compared with those of industrial metal materials and they are accompanied with large deformation.The aim of this investigation is to examine the impact testing method and impact energy absorption for a rubber-chip board specimen and its manufactured products made from the chip of used vehicle tires. In the present study, first, the large arrangements of Hopkinson bar using a falling weight were designed and produced by way of trial In order to match the mechanical impedance between the employed materials and the Hopkinson bar, and take a long time impact, PMMA bars of 45 mm in diameter and 2000mm in length were utilized as an input bar and an output bar as well as a striking bar in the SHB. Second, Five kinds of rubber-chip specimens were fabricated and employed in impact compressive tests by the Hopkinson bar set-up, together with static tests. Consequently, reasonable results were repeatedly obtained and it was found from a series of the experimental results that the impact compressive strength of rubber-chip board was remarkably influenced by strain rates. Moreover, impact tests for a rubber cushion drum was carried out and discussed on relaxation of impact force and energy absorption against collision of vehicles

Split Hopkinson Bar方法（SHB）已被广泛用于压缩撞击测试。但是，尚未建立用于低机械阻抗材料（例如橡胶或软塑料）的SHB方法，因为它们的变形强度与工业金属材料的变形强度非常小，并且伴随着较大的变形。该调查的目的是检查影响橡胶板板和橡胶板的产品的影响方法，并用来吸收橡胶板和其制造产品的能源。 In the present study, first, the large arrangements of Hopkinson bar using a falling weight were designed and produced by way of trial In order to match the mechanical impedance between the employed materials and the Hopkinson bar, and take a long time impact, PMMA bars of 45 mm in diameter and 2000mm in length were utilized as an input bar and an output bar as well as a striking bar in the SHB.其次，霍普金森棒设置制造并使用了五种橡胶芯片标本，并在撞击压缩测试中使用了静态测试。因此，反复获得了合理的结果，并从一系列实验结果中发现，橡胶芯片板的影响受到应变率的影响非常明显。此外，对橡胶垫鼓的撞击测试进行了，并讨论了撞击力和吸收能量的放松，以防止车辆碰撞
