Research on Influence of rotation velocity on projectile penetration ability

Abstract This paper takes the 35mm armor-piercing projectile as research object, and uses ANSYS LS-DYNA dynamic analysis platform to simulate process of penetrating armored steel plate under different rotation speeds by using Johnson-Cook constitutive model. The results show that speed has a certain influence on penetration performance projectile: will have effects contact stress target in later period penetration, resulting resistance with speeds;the ability first decreased then increased increase speed. guiding significance for improving interception efficiency anti-air targets terminal air defense anti-missile equipment.
