【摘要】 通过AUTODYN进行了多爆源在多舱室内爆炸仿真,分析了爆源的数量和布置方式对内爆毁伤效应的影响,基于单爆源多舱室内爆毁伤等级划分标准,提出了多爆源多舱室内爆最优爆源数量的估算方法。结果表明:存在最佳的爆源数量和空间布置方式,能够将爆源释放的能量充分利用,实现对多舱室结构的最大毁伤。在本文所研究的多舱室结构中,当爆源数量为2且爆源间隔舱室布置时,对多舱室整体毁伤效果最佳。仿真和实验验证了最优爆源数量估算方法的有效性。更多还原

【Abstract】 The simulation of multi-explosion sources blast in multi-cabin was carried out by AUTODYN, and the influence of the number and arrangement of explosion sources on the damage effect of implosion was analyzed.Based on the classification standard of damage level when a single source explosion blast in multi-cabin, a method for estimating the optimal number of explosion sources when multi-explosion sources blast in multiple chambers was proposed. The results show that there is an optimal number of explosion sources and space layout, which can make full use of the energy released by explosion sources and achieve the maximum damage to multi-cabin structure.The results show that there is an optimal number of explosion sources and space layout, which can make full use of the energy released by explosion sources and achieve the maximum damage to multi cabin structure. In the multicabin structure studied in this paper, when the number of explosion sources is 2 and the explosion sources are arranged in compartments, the overall damage effect of multi-cabin is the best. Simulations and experiments verify the effectiveness of the calculation method for the optimal number of explosion sources.更多还原
