摘要：

To get the depth model of cratering stage of shaped charge jet penetrating into targets, the penetration process on the target is studied through numeral simulation and experiment. Parameters of cratering stage in penetration into different targets, which are formed from TNT and LX-14 charge with the respective calibers of 56 mm and 82 mm, are obtained by numerical simulation. The depth model of the cratering stage of shaped charge jet penetrating into targets is built by data fitting. Both of the COMP B charge simulation and experimental validation are conducted. The results show: the error between the calculated value and simulation value based on depth model is 4.6% and the error between theoretical value and experiment value is 4.8%, which indicates that the model can be used to calculate the depth of the cratering stage of jet penetrating into targets.
