Abstract:
The penetration process is simulated by software to control a projectile penetrating through a multilayer defense to detonate in a designated layer by the fuze.The acceleration signal of the projectile penetrating the target is obtained by separating the fuze model from the projectile model.Characteristics of the penetration overload signals of positive penetration and oblique penetration are analyzed separately.Layer counting is shielded for a short time because a secondary collision overload may happen when the tail of the projectile is penetrating through the target obliquely.The method is tested by a detonating experiment,and the layer counting detonating control method is correct.
