[ ABSTRACT] In order to investigate the influence of charge size, charge density and state of charge on impact response of composition B, the impact sensitivity of composition B was researched by aself-developed impact device. Effects of charge conditions on the low-velocity impact response of composition B were discussed. The causes of the influence rules were also analyzed. The results suggest that, with the same diameter, the shock threshold of composition B was increased with the increasing of grainsthickness. It was also found that the impact sensitivity was not sensitive to the change of charge density when it approaches to the theoretical density. Moreover, the impact sensitivity of different states presents a remarkable difference that the impact sensitivity of powder is all far over the impact sensitivity of grain.
