摘要
介绍了通用显式动力分析软件包LS-DYNA的显示算法。应用ANSYS/LS-DYNA对线型聚能装药爆破的射流过程进行了二维仿真模拟,对其模拟结果进行了分析讨论;并对两种不同炸药参数的射流过程的模拟结果进行了对比。计算结果与线型聚能射流的物理现象和规律相吻合,说明该计算模型和模拟方法合理、可行,可用于线型聚能切割器的优化设计。
This paper introduces explicit arithmetic of explicit dynamical analysis software package LS-DYNA. Two-dimensional numerical simulation of the jet formation of linear shaped charge blasting had been made using ANSYS/LS - DYNA code. This paper discusses the results of numerical simulation, compares the results obtained from two - dimensional numerical simulation of jet formation of two linear shaped charges with different detonation velocities. The results of numerical simulation are in agreement with physical phenomena and laws of jet formed by linear shaped charge blasting. The study indicates that the calculation model and simulation method are reasonable and feasible, so can be applied to the optimizing design for linear shaped charge cutter.
