Study on the effect of multi-velocity section and different length to diameter ratio rod body on its penetration capability
In order to study the correlation of multi-velocity section,different length to diameter ratio(L/D ratio)rod body and the damage effect on homogeneous armor targets,a finite element model under different working con-ditions was established by using AUTODYN software to accomplish the simulation calculation and comprehensive a-nalysis of the damage on semi-infinite homogeneous armor target impacted by a projectile core with a mass of 4 kg,L/D ration of 10 to 35,velocity between 1 100 m/s to 2 100 m/s,then the correlation value amang the L/D ratio,velocity section and depth of penetration was obtained.The results of this study can provide technical reference for the design and development of rod-type penetrator.
