Title Optimum Design Of Multiple Explosively Formed Projectile(MEFP)
Abstract Since 1980s， many countries have been studying the Multiple Explosively Formed Projectile (MEFP) warhead technology. After decades of development, MEFP warhead has been applied to various weapon systems. Unlike traditional EFP warhead forming a rod-shaped or spherical EFP projectile, MEFP warhead can produce many projectiles, which greatly improves the probability of hitting the target.
This paper analyzed the MEFP warhead types and studied MEFP warhead MEFP various structural parameters on the impact of the molding process, the structural parameters obtained MEFP EFP molding parameters were investigated. SOLIDWORKS software application created five liner arranged in different ways MEFP warhead structure three-dimensional model, through TRUEGRID software to establish the structure of the fourth MEFP warhead finite element model, using AUTODYN software warhead molding process numerical simulation, simulation of the liner arranged manner were investigated MEFP molding obtained liner arranged manner MEFP head speed, aspect ratio and the scattering angle of the curve, to further optimize the design for the future MEFP warhead to provide a reference.
