| Abstract: | Using the analogue theory, the process of shaped charge jet penetrating steel target is analyzed, and the relations of the analogue models are established, the analogue parameters are gained. With the model, the numerical results indicate that, the shaping of the model accord with the analogue law, and the depth of penetration on steel target also satisfy simulation ratio. Analogue model will be used for numerical simulation, so we can reduce the amount of computation and the time of computation with lower cost in the conditions of guaranteeing the accuracy. |
