    Abstract
  • By using the dynamic finite element software LS-DYNA, we simulated the working process of a novel emulsion explosive pressure desensitization device, and investigated the characteristics of its flow field distribution and the influence of its structural design on the experimental results.The comparison of simulation and experiment results shows that the row spacing is the critical factor that determines the degree of accuracy in experiment.For the novel dynamic pressure desensitization equipment, when the radius of the emulsion explosive is 2cm and the weight of RDX is 10g, the smallest row spacing, which minimizes the effect of the emulsion explosive in the front row on that in the back row, is determined as 20cm.Therefore, in order to decrease the experiment error, we can decide on the smallest row spacing through numerical simulation before the dynamic desensitization experiments take place.Our work can serve as a reference for the further research.
