Abstract

In order to educe the influence rule between thickness of RHA, impact velocity and penetration aftereffect of steel shell PELE, a series of PELE projectiles impacted differently thick RHA with different impact velocity, and the number and the distributing of fragment perforation were analyzed. The results indicate that the number of fragment takes on a quadratic function relation to impact velocity and thickness of RHA, the angle of splashing fragment embodies a quadratic function relation with impact velocity and a linear function relation to thickness of RHA. Impact velocity influences the number of fragment more than the angle of splashing fragment. Reducing the thickness of RHA makes for enlarging the angle of splashing fragment under a certain condition.

Key words： PELE; impact velocity; thickness of RHA; number of fragment; angle of splashing fragment
