Simulation study of shaped charge collapse process and optimal standoff determination

In this article, the new method for shaped charge warhead optimal standoff determination is developed based on the ANSYS AUTODYN simulation. The warhead standoff is determined on the assumption of the continual jet velocity behavior. The liner material is accelerated and collapsed under the high detonation pressure. The chosen simulation method is used for the process evaluation using the published PG-7V shaped charge for standoff determination. This article, on the other hand, introduces results of simulation of the waveshaper effect on the liner collapse process and on the jet formation and jet velocity. The Eulerian meshing was used to describe the collapse process of the conical liner. © 2019 IEEE.
