摘　　要：通过对所设计战斗部及靶场参数进行计算与可视化仿真以判断战斗部毁伤威力。使用理论模型对战斗部在相应靶场的静爆过程进行数值仿真,并基于Unity3D技术和仿真数据创建3D场景与静爆场相关数理模型,实现仿真计算数据与3D模型动画全程数值拟合,并支持用户在3D场景中多视角、可缩放观察静爆场物理过程。通过系统仿真实验结果分析可知,系统数值计算与可视化3D模型动画拟合效果良好,用户交互体验较佳,能为复杂破片战斗部实弹设计与实验提供威力评估依据。The damage power of the warhead can be judged by making calculation and visualized simulation to the designed warhead and the shooting range parameters.Digital simulation is made to the static blasting process of the warhead in corresponding shooting range by using the theoretical model.Unity3D technology and simulation data are used for creating the mathematical model of the static-blasting field and the 3D scene thus to realize numerical fitting of the simulation data and 3D model animation and enable the users to observe a multi-view scalable physical process of the static-blasting field in 3D scenes.The analysis of system simulation experiment results show that the fitting of system numerical calculation and 3D visual model animation has good effects and the user interaction experience is satisfying which can provide a basis for making power evaluation to the design and experiment of complex fragment warhead.
