Inhalt:
The distribution of shock wave load after the explosion of munitions in the compartment is an important basis for assessing the damage of munitions to the ship's compartment. Using AUTODYN software simulation study of the explosion of ammunition in the compartment, analysis of the charge and aspect ratio on the impact of shock wave load distribution in the compartment under the implosion, the results show that: (1) wall reflection overpressure enhancement times 2-3 times, the two sides of the corner overpressure enhancement times -6 times (2) when the aspect ratio of 1/1, the corner enhancement times 7.88 times, with the increase in the aspect ratio corner overpressure Gradually decreases, when the aspect ratio is 3/1, the overpressure enhancement at the corner is 3.46 times.
