Fuze High Speed Fragment Impact Ceramic Material Protection Structure
Aiming at how to protect the detonating charge column of fuze under fragment impact environment to reduce the response level of the detonating charge column,a metal-ceramic-metal multilayer composite protection structure of the detonating charge column of fuze was designed according to the protection mechanism of ceramic material and the structural characteristics of detonating charge column.The protective properties of different ce-ramic materials were compared by numerical simulation,the results show that,compared with the original fuze structure the protection effect of SIC ceramic material is the best.The peak pressure of explosive and the impact velocity of fragment were significantly reduced.The effectiveness of the buffering structure was verified by frag-ment impact experiments.The ceramic material protection structure could effectively reduce the response level of the detonating charge column of fuze under fragment impact environment.
