活性破片作用后效靶板耦合能量分布特征

To reveal the coupling energy distribution characteristics and mechanism of the reactive fragments penetrating the rear target plate, the ballistic gun experiment of the reactive fragment impacting the double-layer target plate is carried out. The bullet-target interactive behavior is recorded with high-speed photography, and a damage behavior model of the reactive fragments impacting the rear target plate is established based on the damage effect of target, the fragmentation theory of the fragments penetrating the target, and the secondary fragment energy distribution. The results show that the kinetic and chemical energies predominate in different impact velocity intervals during the process of reactive fragments impacting the rear target plate. With the increase in impact velocity, the reactive fragments are fully activated, and the damage of reactive fragments to the rear target plate changes from chemical energy to kinetic energy.
