Abstract

In order to study the influence of the structure of prefabricated fragments warhead on the killing power, a projectile structure scheme with two prefabricated fragments installation modes, which are external and internal, is designed based on a certain grenade, the simulation process of warhead explosion and fragmentation dispersion is accomplished by AUTODYN, and the characteristics of fragmentation parameters under the two structures are obtained. The results show that the fragment velocity of the prefabricated warhead is 4.7% higher than that of the external warhead. The built-in prefabricated fragment warhead structure is more conducive to the formation of effective fragmentation. The reduction of the cylinder wall thickness of the prefabricated fragment warhead will lead to the premature rupture of the projectile body, and lead to the decrease of the initial velocity of the whole fragment.
