Hopkinson pressure bar and X-ray CT tomography scan equipment and devices were used to test and evaluate a bridge-wire detonator′s performance in high acceleration overload environments.According to test results, the failure mode and the weak properties were obtained.A structure reinforced detonator was designed through materials optimization, structural optimization and reinforcement, transition charge solidified.The results show that reinforced detonator can withstand the impact of more than 100000 g and pulse with width of about 100 μs.After the high acceleration impact, the detonator performance and basic structure nearly do not change, revealing that the performance of bridge-wire detonator against high acceleration overload is enhanced.
