摘要：The formation process of the jet induced by shaped charge was simulated based on Adaptive method, ALE method and SPH method separately. The relationship between the jet head velocity and time, velocity and position on the shaped charge liner, and velocity distribution along the jet formed were analyzed. The characteristics and the approximation to relevant experimental data of the three numerical methods were compared. The results derived from all these three methods are in line with the forming process and mechanism of the jet. And the result derived from SPH method is the most approximating to the experimental data.
