    Abstract
  • In this work we simulated the process of the jet penetrating into a target with a V-shaped reactive armor using the three dimensional finite element code (LS-DYNA), and performed the corresponding experiment to study the effect of the impact point position on the jet.The numerical simulation results are in good agreement with the experimental data.The results show that the disturbance degree of the jet was obviously different when the impact point was positioned differently.With the increase of the distance between the impact point and the bottom in the center line of the V-shaped reactive armor, the penetration depth of the jet in the witness target exhibits a tendency to decrease first and then increase.When the distance between the impact point and the top of the V-shaped reactive armor is 6.25 times that of the jet diameter, the penetration depth is minimum and the protective capability at this point is optimal.Moreover, the protective capability of the top is superior to that of the bottom.
