    Abstract
  • The shaped charge jet can be applied to explore and enlarge the escapeway for drivers and passengers trapped in an ignited bus due to its special cutting ability.In this research, we established a numerical model of this scheme to study the performance of the shaped charge jet by using the ANSYS/LS-DYNA finite element software.Simulation results show that despite of the negative influence of both the asymmetry of the shaped charge and the diffraction of the detonation wave in curvature segments on the penetrating ability of jet, the cutting ability of the shaped charge jet can be sustained with reasonable parameters.It can smoothly explore and expand the escapeways within microseconds without any remaining obstacles for physical vulnerable groups.Thus the scheme can be used as an effective countermeasure for the ignited bus.
