Abstrakt:
The acceleration of explosively driven aluminum flyer was successfully simulated using LS-DYNA code. The properties of the explosive (A-IX-1, RDX/binder 95/5) was completely calculated by Explo5 program (detonation velocity and pressure, JWL parameters for the expansion isentrope).The results were compared to the experimentally obtained velocity profile, measured previously with PDV. The both curves agree by shape, velocity values at the individual steps and their duration. Also the terminal velocities agree very well.
