【 摘 要 】

Comparing the anti-detonation property and shock wave attenuation law of the single material structures, composite material structures and sandwich material structures are simulated by AUTODYN. The simulation on the structures with different combination show that, the aramid fiber material as base material in touched with the explosives, can greatly reduce the shock wave in identification board. For different material structures of the attenuation rule of shock wave, numerical simulation results show that the sandwich structure of the shock wave attenuation ability is more effectively than a single material structure. Based on the anti-detonation performance in different arrangement of the material structure, anti-detonation structure optimization design scheme is given according to the simulation results.
