Abstract

In order to explore the penetration efficiency of ceramic fragments and post-target damage effect,ballistic impact test and FEM-SPH algorithm were used in the study to study the penetration efficiency of ceramic fragments and the damage effect of debris cloud after target by changing the penetration velocity,fragment size and penetration angle of ceramic fragments.The results show that the penetration ability of ZrO2 ceramic fragments is stronger than that of Al2O3 ceramic fragments.With the increase of penetration velocity and fragment size,the reaming effect of aluminum target is enhanced,the volume of post-target debris cloud,the mass loss of after-effect target,the perforation diameter and the damage area increase.With the increase of the penetration angle,the perforation shape of the aluminum target changes from circular to oval,the perforation area decreases first and then increases,the volume of post-target debris cloud,the mass loss of the after-effect target,the perforation diameter and the damage area increase first and then decrease.The research results are of reference significance for the evaluation of the damage caused by ceramic fragments penetrating the outer shell of spacecraft and the internal circuit board.

Key words： ceramic fragment; aluminium target; penetration velocity; fragment size; penetration angle; after-effect target
