摘要:

当前对于炮弹外弹道的研究主要以数据处理分析为主,缺乏以动态实时直观的仿真方式对外弹道进行分析和处理。在介绍了外弹道数学模型,分析了各种数值仿真方法的基础上,通过构建基于OpenGL的三维视景仿真环境和基于Matlab的二、三维坐标轴,实现了基于数值仿真实时驱动的弹道可视化仿真平台,借助此平台对炮弹的飞行轨迹、实时运动姿态及落点散布进行了仿真验证和分析,得到了不同风速对炮弹飞行轨迹的影响程度。

关键词: 外弹道, 数值仿真, 视景仿真, 落点散布

Abstract:

Current research on external ballistic trajectory of the shells is mainly based on data analysis,lacking dynamic realtime and intuitive simulation and analysis of external ballistic trajectory.In the paper we make a detailed description of mathematical model about external ballistic trajectory and analyze various methods for numerical simulation.By constructing two modules named threedimensional scene simulation environment based on OpenGL and twodimensional coordinate axes based on MATLAB,we achieve a visualization simulation platform based on realtime numerical simulation.The platform can analyze the ballistic trajectory,realtime motion gestures and fall point dispersion;it also shows the impact of wind speed on ballistic trajectory in detail. 

Key words: external ballistic trajectory;numerical simulation;scene simulation;fall point dispersion
