The Forming And Cutting Simulation Study, Based On The Ansys / Ls-dyna

Study of the shaped charge explosively formed projectile formed and its cut technique is background on the modern battle condition and research multifunction function combat. The cut technique of the shaped charge explosively formed projectile is one of the more important artifice to realize the shaped charge explosively formed projectile playing multifunction actions. In this paper, finish the numerical simulation of the shaped charge explosively formed projectile and its cut technique by dint of ANSYS/LS-DYNA fluid dynamics finite element analysis procedure, based on abroad review correlation technique inside and outside, established of the shaped charge explosively warhead geometry model and finite element model in reason, selecting the material and its parameter and controlling the process of the calculation logically. Then analysis explosively formed projectile formed and its cut mechanism introduction. The result is consistent by comparing with ancient experiment.The details mainly include:1) The arithmetic theory and process of the analysis problem by ANSYS/LS-DYNA dynamics finite element analysis procedure;2) Establish the geometry model and finite element model of the explosively formed projectile formed and its cut;3) Studying 2D and 3D numerical simulation of the explosively formed projectile formed and its cut technique;4) Prove the study correctness validity by compare with ancient experiment.
