Investigation of explosive effect to followed projectiles by shaped charge of tandem warhead

The explosion of shaped charge of tandem warhead and the impact process on followed projectile of impulse are simulated with a numerical hydrocode of AUTODYN. The maximum acceleration response and kinetic energy attenuation of followed projectile during impact process are analyzed under different projectile mass and diameter. The result indicates that the projectile's maximum acceleration decreased, remainder kinetic energy increased with followed projectile mass increased. An equation of followed projectile's residual velocity with projectile mass is concluded based on simulation results, and it is validated by experimental results.
