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

分离式霍普金森杆法（SHB）是一种广泛应用于压缩冲击试验的方法。然而，用于低机械阻抗材料如橡胶或软塑料的SHB方法尚未建立，由于橡胶材料的变形强度与工业金属材料相比非常小，且变形量很大，本文研究了橡胶材料的冲击试验方法和冲击能量吸收特性。用废旧汽车轮胎碎片制成的碎料板试样及其制品。为了使所用材料与Hopkinson杆之间的机械阻抗匹配，并能承受较长时间的冲击，采用直径45 mm、长2000 mm的PMMA杆作为输入杆、输出杆和撞击杆。其次，利用Hopkinson压杆装置对五种橡胶片进行了冲击压缩试验和静态试验。结果表明，橡胶刨花板的冲击压缩强度受应变率的影响很大。并对橡胶缓冲鼓进行了冲击试验，讨论了缓冲鼓在汽车碰撞中的冲击力松弛和能量吸收问题
