In order to improve the penetration performance of projectiles toceramic composite armor, the nose of 30mm standard projectile is replaced by atoughened ceramic nose, and the armor-piercing performance of ceramic-noseprojectile to ceramic/A3 steel composite targets has been experimentallyresearched. Under the guidance of Impact Dynamics Theory, this article mainlyanalyzed and compared, under DOP method, the armor-piercing performancebetween 30mm ceramic-nose projectile and 30mm standard projectile to theceramic/A3 steel composite targets, especially focusing on the effects made bydifferent nose structures and materials. Under same conditions, a comparativeanalysis on the aperture and the depth of perforation on the armor plates as well asthe residual mass of bullet core has been given. A numerical simulation has beenbuilt and computed by ANSYS/LS-DYNA, whose results mainly meet the testresults. Combined with the simulation results, further analysis on the penetrationperformance is given in terms of the residual mass of bullet core. The results showthat the ceramic nose has a great effect on the protection of bullet core which laysa foundation for its applying in other warheads.
