摘要

In order to improve the jet velocity of the traditional conical-shaped charge structure, a parabolic-shaped charge structure is proposed by increasing the length of the busbar of the shaped charge. The results show that the metal jet formed by the explosion of parabolic-shaped charge structure has stable flight performance and deep penetration depth. To this end, the static explosion tests of parabolic-, cone- and semicircular-shaped charge structures penetrating steel plates were carried out. Under the condition of the same charge and blast height, the explosion damage characteristics of three shaped charge structures on steel plate structures are compared. The perforation diameter of the parabolic- and conical-shaped charge structure is 20 mm, and the perforation diameter of the semicircular-shaped charge structure is 19 mm. The penetration depth of the parabolic-shaped charge structure is 1.25 times and 1.5 times that of the cone and semicircular structures, respectively. The results show that the parabolic-shaped charge structure has a longer penetration depth than the traditional-shaped charge.
