爆炸与冲击数值模拟的可视化

VISUALIZATION OF EXPLOSION AND SHOCK

针对二维多物质流体弹塑性程序 SMMIC(自行开发 )结果 ,设计了一个切实可行的二维爆炸场可视化工具软件 ,以此来研究二维爆炸与冲击数值模拟结果的可视化问题。用该软件对有或无防护挡墙的二维爆炸场中冲击波的传播过程 ,金属射流形成过程和混凝土中的爆炸效应进行了可视化处理 ,可视化的效果比较令人满意 ,结果不仅可展现爆炸与冲击过程的整体概貌 ,而且可清晰地显示爆炸与冲击过程的细微过程 (如爆炸场中冲击波遇障碍物后的反射 ,绕流和马赫反射等 )。

The problem of visualizing explosion and shock is studied, and a useful and practicable software tool used to visualize two dimensional explosion and shock is developed for the implementation of two dimensional multi material hydro elastoplastic programs Based on this tool, the shock process of explosive field with a protective wall, the process of metal jet and the explosive effect in concrete are simulated by the program SMMIC The visualized results are satisfactory, and capable of displaying the overview of explosive and shock, giving details about the transmission of shock wave in the field, such as reflection, flow over an obstacle and Mach reflection, and the like
