摘　　要：如何快速、准确预估弹丸落点,是一维弹道修正弹仿真分析的关键。通过分析弹体气动外形建模、弹箭运动的数学模型建模,设计了一种修正弹药外弹道简化仿真模型,并与6自由度刚体弹道的相对准确落点比较,计算精度满足使用要求,且计算时间短,可以用于一维弹道修正弹仿真。How to predict the impact point of projectile quickly and accurately is the key to the simulation analysis of one-dimensional trajectory correction projectile.By analyzing the aerodynamic shape modeling of the projectile and the mathematical modeling of the motion of the projectile,a simplified simulation model for modifying the exterior trajectory of the projectile was designed and compared with the relatively accurate landing point of the 6-dof rigid body trajectory,the calculation accuracy meets the operational requirements,and the calculation time is short,so it can be used in the simulation research of one-dimensional trajectory correction projectile.
