Abstract
Underwater explosion of aluminized explosive and its character were simulated by using AUTODYN software. Effect of non-ideal detonation on shock wave and bubble pulsation was investigated numerically. The aluminized explosive of cylindrical charge with a weight of 1 kg was detonated underwater at a depth of 5 m in an explosion test tank. The numerical results show that the Miller model could precisely simulate the phenomenon of the shock wave and bubble pulses and the simulation data could be consistent with the experimental data. Moreover, the effect of charge parameters and detonation mode on the peak pressure of shock wave has been analyzed and summarized. This work has a certain value to the calculation and simulation for further research.
