摘要: 理论上分析了末敏弹系统伞、伞盘、弹三刚体间的力学关系,考虑了系统的连接方式和约束、分析了伞绳弹性,建立了三体运动的数学模型,算例表明所描述的运动与实测运动规律和扫描特性相符,因此该模型可用于末敏弹总体和扫描装置的分析和设计。

Abstract: This paper studies the dynamic relations of three rigid bodies among parachute, plate and projectile of Target Sensitivity Projectile (TSP), analyses the joining mode and binding, and considers elasticity of the parachute rope. The equations are established. An example indicates the consistency of scanning characteristics and the rule between the real movement and the movement described by the model. So the model can be used in the TSP total design and scanning equipment design.
