Abstract

The process of wedge-shaped charge's interference effect and that of sandwich charge's on the jet were numerically simulated using ANSYS/LS-DYNA software.The influence of the wedge angle and that of the charge mass on the velocity and the declination angle of the jet head, the velocity of the slug were analyzed and discussed.Comparison of the obtained results with those of the sandwich charge shows that the interference effects of the wedge-shape charge and the sandwich charge on the jet head are very much alike but their interference effects on the jet slug are different.The movement of the wedge shaped flying-plates can be seen as a 2D composite motion of translation and rotation.When the wedge angle is positive, the cutting jet effect of the wedge-shaped charge is better than that of the sandwich charge.In this case, the deflection of the jet head increases, the velocity of the jet slug decreases, and the effect is enhanced with the increase of the wedge angle.Moreover, as the charge mass increases under the condition that the angle remains unchanged, the contact position of the jet head gradually shifts to the front of the target, the contact time delays, the breakup time of the jet slug arrives earlier, and the rotation of the plates slows down.
