Abstract

To study the effect of the projectile shape's influence in rotary penetration depth(RDP) of concrete target, LS-DYNA was used to simulate the process of the projectile rotary penetrating in the target under different projectile shape and different velocities. Simulation results prove that drilling-head shape projectile could increase RDP with low velocity, when ogive-nosed shape projectile could do well with high velocity, so composed of drilling-head and ogive-nosed shape could improve penetration performance; when rotary velocity is 50000r/min, the composed shape projectile the most optimal increasing rate of RDP with the axis velocity of 300-400m/s. Under excellent loading condition, the depth of the cutting slot has the larger effect on penetration depth than the slope, the cutting slot shape that relatives to target surface has little effect of the penetration. Based on the validation test of penetrating into targets, the simulation results are coordination with the experiment data.
