Abstract

Results were presented by three-dimensional simulation of the detonation development in the shaped charge with wave-shaper. The calculation was performed using finite-element code LS-DYNA, the calculated jet head velocity was in good agreement with experimental result, based on this, the effects of various wave-shaper material and configurations on jet performance were analyzed. It suggests that spherical detonation wave is converted into a converging detonation wave by a wave shaper, and the attack angle of detonation front decrease. There is an optimum diameter when the thickness is kept constant, jet tip velocity increases with the wave-shaper diameter, but decreases when it is larger than this value. The attack angle of detonation front with double truncates cone wave shaper is less than that of the single truncates cone one, and jet tip velocity increases by 18% than that produced by shaped charge without wave shaper.

Key words： mechanics of explosion; shaped charge; wave-shaper; detonation wave; jet velocity
