Numerical Simulation and Stress Testing Research on Elliptical Bipolar Linear Shaped Charge

摘要：

Based on Shaped Charge technology, the method of linear cracks of directional fracture in rocks controlled blasting by shaped charge and the Elliptical Bipolar Linear Shaped Charge with low detonation velocity explosive was presented in this paper. Hie stress testing experiment was carried on by the stress sensor for analyzing the characters of cumulative pre-split-ting of the shaped charge. A numerical calculation scheme for simulating the formation and movement of jet was developed based on the Ansys/Ls-dyna. The damage of the concrete target penetrated by the jet was showed in the numerical simulation. The results of experiment and the simulation indicted that the shaped charge can form good effect on cumulative energy and produce good pre-splitting blasting effect At the same time, the safe, economic and environmental benefits had been clearly made.
