Computer Simulation Study of Underwater Blast Wave Loading of a Typical Combatant

Abstract

In order to study the forward shock wave load characteristics of underwater explosion of three different typical warheads, the blasting warhead, spherical shaped charge warhead and conical shaped charge warhead are numerically simulated by using the finite element simulation software, and the forward shock wave load distribution laws of three different warheads are analyzed. The results shows that the forward shock wave load distribution of the three typical warheads tends to be consistent with the increase of axial distance. The rarefaction wave formed in the front air chamber of the warhead makes the peak pressure of the shock wave around the air chamber less than the peak pressure of the lateral shock wave. At the same axis position, the peak pressure of shock wave of blasting charge is greater than that of shaped charge, and the peak pressure of shock wave of conical shaped charge is greater than that of spherical shaped charge. Under the same charge quantity and explosion height, the damage effect of conical shaped charge on the target plate is better than that of spherical shaped charge.
