Influence of Liner Material on Formation of Multiple Explosively Formed Projectiles Warhead Parameters

Abstract:

The law of influenced material of liner is researched by numerical simulation.Multiple explosively formed projectiles (MEFP) forming process is numerically simulated with different liner material,such as copper, aluminum, iron and so on.The law that the formation parameters of MEFP such as velocity, length-diameter ratio and radial dispersion angle,influenced by the density and ductility of liner material is educed.It reaches the conclusion that the velocity and radial dispersion angle of projectiles decreases 58% and 56% with the increasing density of the liner material; the length-diameter ratio of central projectile increases276%with the increasing ductility of the liner material, so in order to acquire good formation of MEFP parameters, the appropriate density and higher ductility should be chosen.
