In order to study the damage effect of long-rod kinetic energy projectiles with different velocity on target board with different velocity by different attack angle and impact angle,the penetration was simulated by ABAQUS,the residual velocity,deflection angle,torsion angle,the residual mass of kinetic energy projectile and the damage area of plate were analyzed.The result indicates the angle of attack in 60 degrees or so is better for penetration ability,and the smaller or larger the angle of attack is,the better is the damage ability;The damage ability of the kinetic energy projectile declines as oblique penetration.
