Abstract

Abstract

Based on the design of a profiled rod, a dynamics model was proposed for the profiled rod driven by dentonation. The motion process of the profiled rod driven by dentonation was simulated by ANSYS/LS-DYNA. The model for the profiled rod after detonation and the initial velocity were achieved. Considering the aeroelastic deformation caused by the profiled rod flying in air fluid filed, the profiled rod was regarded as a flexible body, the motion process of the profiled rod flying against air resistance was simulated by ADAMS. The computed results show that the proposed simulation method can describe the motion states of the profiled rod accurately after detonation and provide a reference for the design of the profiled rod warhead.
