The interactions between the high-speed waterjet of 500 m/s and the condensed explosive have been simulated by LS-DYNA3D code with Lagrange method. The pressure distributions in the explosive at different times and the pressure histories at different elements of the explosive have been calculated. On the basis of numerical simulation, the sound speeds of the explosive have been determined. The numerical simulation results accord with the theoretical analysis. During the process of the interaction between the high-speed waterjet and the condensed explosive, the numerical simulation results show that the pressure decreases with the increase in the radial distance of the element and the maximum pressure occurs nearby or in front of the head of the penetrating waterjet.

利用LS-DYNA3D软件并采用Lagrange算法,对500 m/s的高速水射流与凝聚炸药的相互作用过程进行了数值模拟;对不同时刻凝聚炸药中的压力分布以及不同径向、轴向处的压力历史进行了分析;确定了所选凝聚炸药的声速。数值模拟的结果与理论分析的结果之间具有很好的一致性。模拟结果表明,在高速水射流与凝聚炸药相互作用的过程中,凝聚炸药药柱截面上的压力随径向距离的增加而降低;药柱中的最大压力出现在水射流头部附近或水射流头部的前方。

利用LS-DYNA3D软件并采用Lagrange算法,对500 m/s的高速水射流与凝聚炸药的相互作用过程进行了数值模拟;对不同时刻凝聚炸药中的压力分布以及不同径向、轴向处的压力历史进行了分析;确定了所选凝聚炸药的声速。数值模拟的结果与理论分析的结果之间具有很好的一致性。模拟结果表明,在高速水射流与凝聚炸药相互作用的过程中,凝聚炸药药柱截面上的压力随径向距离的增加而降低;药柱中的最大压力出现在水射流头部附近或水射流头部的前方。

The interactions between the high-speed waterjet of 500 m/s and the condensed explosive have been simulated by LS-DYNA3D code with Lagrange method. The pressure distributions in the explosive at different times and the pressure histories at different elements of the explosive have been calculated. On the basis of numerical simulation, the sound speeds of the explosive have been determined. The numerical simulation results accord with the theoretical analysis. During the process of the interaction between the high-speed waterjet and the condensed explosive, the numerical simulation results show that the pressure decreases with the increase in the radial distance of the element and the maximum pressure occurs nearby or in front of the head of the penetrating waterjet.
