Abstract

Abstract

Due to the difference in physical quantities such as density and pressure, the forming process of explosive formed projectile(EFP) in air and water is quite different. In order to optimize the design scheme of underwater EFP, the simulation study was carried out using AUTODYN finite element software and the specific effects of the seven variables of the charge were discussed in detail. A set of design parameters suitable for underwater EFP charge is produced. According to the simulation results, the optimized design parameters of the EFP charge with a total mass of 1 kg are: the aspect ratio of the explosive is 1.5, the type of explosive is HMX with a higher detonation speed, the material of the liner structure is copper, and the tangential cone angle is 145°, the wall thickness $\delta$ is 2 mm, the length of the air field is 3 times the charge radius, and the initiation radius r is 0.4 times the charge radius. This scheme has a good effect on optimizing EFP speed,aspect ratio and kinetic energy.
