Abstract

Abstract

According to the characteristics of the detonation loading process in prefabricated fragment warhead, we designed the sliding detonation unit test model, and obtained the initial velocity and the damage of the prefabricated fragments and light shell under two typical arrangements by the X-ray photographic method, and analyzed the influence of different impedance matching structures on the accelerating character at the same time.The results show that the initial velocity of the prefabricated fragments situated outside the shell (sequential impedance matching structure) with slight damage is relatively high, whereas that of the prefabricated fragments situated inside the shell (reverse impedance matching structure) with stratification cracks is relatively low.
