摘要
介绍了导弹末敏子弹在减速阶段的运动特性。首先,简单介绍了导弹末敏子弹的作用原理和减速阶段的工作过程,将末敏子弹减速阶段的弹道分为自由坠落阶段和减速伞减速减旋阶段。然后分析了两个阶段的受力情况,并分别建立了单质点运动学模型和质点-刚体动力学模型。该模型可以为末敏弹的总体设计及稳定扫描装置的设计提供帮助,可以用于末敏弹中的外弹道研究。
This paper deals with the dynamics characteristic of terminal-sensitive submunitions in missile.Firstly, the principle and working process of terminal-sensitive submunitions in missile are simply introduced,and the ballistic trajectory of the terminal-sensitive submunition is divided into two stages:freely falling stage,the deceleration and dispinning stage with decelerating parachute.Then.the forces and moments of the two stages are analyzed,on that basis,the single particle kinematics model and the particle-rigid body dynamics model are established.The models can provide the overall design and the stable scanning equipment design of the terminal-sensitive submunition with some helpful references,and can be used to the exterior ballistic of terminal-sensitive submunitions.
