摘　　要：针对实弹射击训练场地条件限制大、训练耗费较高、安全保障困难以及训练内容无法适时弹性变更的问题,提出了仿真系统基于射表的外弹道仿真方法,以射表数据为输入、系统设定外界环境为修正的抛物线拟合弹丸质心方程组,通过方程组拟合获得较为切合实际外弹道的曲线模型;以C++作为开发语言对外弹道进行拟合运算,实时显示弹丸运动轨迹,由此获得室内训练场环境的模拟模型,并将误差控制在一定范围内;使用Unity3D为虚拟引擎,将驱动坦克与炮弹引入三维可视化实体模型,并搭建相应地形场景与命中效果;应用3D Studio Max软件建立坦克与炮弹实体模型,体现战场环境多变性与射击系统过程的仿真模拟,为外弹道及射击仿真训练系统提供了研究基础。Aiming at the problems of the limited conditions of the real firing training ground,the high training cost,the difficulty of safety guarantee and inability to change the training content in a timely and flexible manner,the external ballistic simulation method of the simulation system based on the firing table is proposed.The parabola which takes the firing table data as the input and the system setting the external environment as the correction is used to fit the projectile centroid equation group,which is more practical through the equation group fitting curve model of exterior ballistic;using C++ as development language to fit exterior ballistic,real-time display the trajectory of projectile,so as to obtain the simulation model of indoor training field environment,and the error is controlled within a certain range;Using Unity3D as virtual engine,driving tank and projectile are introduced into the three-dimensional visual entity model,and corresponding terrain scene and hit effect are built;the 3D Studio Max software is used to establish the solid model of tanks and shells,which reflects the variability of the battlefield environment and the simulation of the shooting system process,which provides a research basis for the outer trajectory research and shooting simulation training system.
