Numerical Simulation of the Kinetic Energy Projectile Deflected by Targets Moving along Transverse Direction

Abstract:

When the kinetic energy projectile into concrete target movement, angle of attack can affect the penetration process of ballistic performance, resulting deflection effect, thus affecting the penetration depth. For the analysis of kinetic energy projectile penetrating the lateral movement of the target deflection model, using the finite element simulation software for lateral movement of the target missile penetrates the process of numerical simulation. The results showed that: rigid lateral movement of the target missile and projectile kinetic energy projectile velocity has some deflection effect. Playing the role of the kinetic energy of the lateral movement of the target, the missile body yaw angular velocity increases and then decreases after the first, but not so obvious kinetic energy projectile yaw.
