    Abstract
  • To identify the properties of the three-wave point for aluminized explosives in the near-earth air blast, we simulated the explosion process of 3 kinds of RDX-based aluminized explosives, i.e. HL-01 (RDXph), HL-02 (85% RDXph+15% Al) and HL-03 (70% RDXph+30% Al), using the ANSYS/AUTODYN software.The results show that the pressure histories and the near-earth overpressures obtained from the simulation almost overlapped those measured from the experiment, indicating that the chosen model and parameters were appropriate.The comparison of the simulation results with those from the empirical chart shows that it was not suitable to calculate the height of three-wave point for aluminized explosives from the empirical chart, while it was so by simulation.At the same explosion height, the height sequence of three-wave point was HL-03 > HL-02 > HL-01.For the same explosive, the height of three-wave point increased with the decrease of the explosion height.
