Numerical Simulation of Shaped Charge Jet

The numerical simulation and contrast analyses for the process of shaped charge jet produced by the liner of different cone angle and the same kind of explosives and the liner of same cone angle and the different kind of explosives are performed by means of the ANSYS/LS-DYNA 3D software.The results show that the shaped charge jet formed by the liner of 53° is short and thick and the shaped charge jet formed by the liner of 43° is long and thin.Higher speed jet can be formed by high energy explosive.This result is in accordance with the mature theory,proving the correctness of numerical simulation model and parameters used in the state equation.This work provides a basis for designing and developing new shaped charge products,and reducing the experiment cost and the development time of new products.
