Abstract

In order to accurately obtain the trajectory characteristics of the triple point in the explosion field, we simulate the characteristics of triple point in the explosion field, using AUTODYN software. The results show that, for cylindrical charges, the smaller the aspect ratio, the higher the height of the triple point at the same measuring point, and the more obvious the rising trend of the triple point where the charge equivalent is the same and the explosion height is same. For cylindrical charges, the higher the detonation point, the higher the height of the triple point at the more obvious the growth rate. Different reflection interfaces have a greater influence on the height of the triple point. At the same measurement point, the height of the triple point formed by the reflection of the shock wave on the rigid interface is higher than the height of the triple wave formed on the concrete floor.

Key words： triple point; charge size; detonation position; reflective interface; numerical simulation
