Numerical Simulation Research on the Effect of Radial Rotation on the Formation of Explosive Forming Projectile

Abstract

In order to study the forming condition of EFP under radial rotation, the numerical simulation of typical explosively-formed projectile (EFP) charge structure in different positions and rotational speeds are completed by using the finite element simulation software LS-DYNA. Simulation results are verified preliminarily by experiments. Results show that the EFP formed under the radial rotation condition has the lateral deflection speed, and the shape is asymmetrical. When the tip of the EFP has horizontal diversion, the tail of the EFP has vertical diversion, and the infection of radial rotation is most seriously, while the rotation location is in the bottom with middle and the donated pointed rotation location followed. Research results also provide a good example for the study of EFP under the radial rotation condition.
