Abstract: The modified Split Hopkinson Pressure Bar system equipped with the high, speed camera is utilized to perform the experimental researches on the dynamic behavior of ring systems made of different materials subjected to impact loading. Correspondingly, comprehensive numerical simulations on the ring systems are conducted by the dynamic finite element software LS, DYNA. The energy absorption features of different ring systems and the influences of different parameters are discussed. The results show that the energy absorption efficiency of the ring systems is relatively high and the system is very valuable for engineering uses.

Key words: ring systems, SHPB technique, energy absorption
