摘　　要：为掌握橡胶材料的抗爆吸能特性,通过SHPB实验系统对3种不同配比的橡胶进行动力学试验研究,对比分析3种不同配比橡胶在不同应变率下的应力应变曲线。结果表明:橡胶动态弹性模量、峰值应力、吸能率随着应变率的增大而增大,低硬度橡胶的动态应变率效应更为显著,橡胶中掺入补强剂和软化剂将大大提高吸能效果。In order to know the energy absorption property of rubber, experimental study on dynamics of three kinds of rubber with different formula was carried out by Split Hopkinson Pressure Bar test, the stress-strain curves under different strain rates were compared. The results show that dynamic young＇s modulus, peak stress, energy absorption rate increase with strain rates increasing. The low stiffness rubber has obvious dynamic strain-rate effect, the addition of reinforcing agent and softener can greatly improve the energy absorption rate of rubber.
