The Velocity Decay Property of Different Shape Fragments for Explosive Anti-Riots Munition

Abstract:

In order to assess the safety of the explosive anti-riots munition, proceeding with the fragment’s force condition was analyzed in the flying process, the dynamical model of the fragment for the explosive anti-riots munition was deduced, then the velocity decay property of different shape fragments were calculated and analyzed also. The results show that the velocity decay of the spherical fragment is slowest, next came the rectangular fragment and the irregular shape fragment, with the same initial velocity (_v0) and separation angle (α), and the velocity decay of the same fragment at α >0 is more quickly than at α <0, with the same initial velocity (v0).
