基于Autodyn-3D的全尺寸定向战斗部破片模拟

Abstract

As trials costs continue to rise it becomes increasingly attractive to design and assess fragmenting warheads using a combined approach of numerical analysis and prototype test firings. This paper describes an integrated methodology where three dimensional Computer Aided Design (CAD) data can be used to create prototype warheads for testing, and as an input to define the warhead geometry in a numerical model. The 3D numerical simulation can produce complete fragment performance data in a format suitable for use in vulnerability modelling tools.

The prototype trials can be used to verify the numerical results and confirm the warhead’s performance. This integrated approach allows fast and efficient analysis of fragmenting warheads.
