    Abstract
  • In order to study the probability ignition behavior of explosive and the influence of sample thickness on ignition in drop weight test, a three-dimensional numerical simulation of brittle explosive PBX-2 is carried out. The three-dimensional numerical simulation method combining the finite element method and the discrete element method is adopted, and the non-uniformity of explosive material is considered. The ignition probability distribution of explosive under different falling height is obtained. The calculation result of falling height is consistent with the experimental result reported in literature. The influence of sample thickness on the temperature rise process and ignition threshold height of explosive in drop weight test is studied. The estimation formula of pressure peak value and ignition threshold with sample thickness is obtained by fitting, which can provide reference for experimental design.
