摘要
将质点映射算法嵌入自主开发的MMIC-2D欧拉型爆炸与冲击问题数值模拟程序中,并在计算程序中加入基于熔化热熔融理论的质量侵蚀模型.利用该程序对弹体高速侵彻混凝土靶板问题进行了数值模拟研究,将数值模拟结果与相关实验数据进行了对比,并对侵彻速度、弹体头部系数等影响侵彻性能和弹体质量侵蚀的相关因素进行了分析.
Based on the Eulerian hydrocode MMIC-2D for explosion and impact problems, both particle mapping method and mass loss model based on heat-melting theory are implanted. High velocity projectiles penetrating into concrete targets are numerically simulated with MMIC-2D. The simulation results are compared with related experimental data, and factors affecting the penetration effect and mass loss of the projectile such as penetration velocity and CRH value are studied.
