摘　　要：对三维爆炸场进行图形仿真,可以便于研究人员对难于直接观察、分析的爆炸场进行全貌和细节的观察和分析。在三维多流体网格法(3DMMIC)数值模拟结果的基础上,采用体视化方法对三维爆炸场进行图形仿真。用VisualC++编制了相应计算机仿真程序,通过实例的仿真结果的动画模拟与理论上爆炸冲击过程的比较,验证了算法的正确性与可行性,仿真效果比较满意。Graphic simulation is an important method to observe and analyze the panorama and the details of explosion and shock processes, which is difficult to observe and analyze directly. On the base of the numerical method of three-dimensional multi-material in cell (3DMMIC), volume visualization is applied to the graphic simulation of explosive field. The relevant simulation software is compiled using Visual C++. The correctness and feasibility are validated via comparing the simulated results with explosive theories. The results of simulation are approved.
