将空间飞行器分为目标和射弹两类,对二者撞击过程中的弹目交汇模型进行研究。在目标构型分析的基础上,基于基本几何形体建立目标等效模型,实现了典型目标的数学描述。考虑弹目构型特征,采用真实实际比例导引建立射弹末制导模型,在此基础上,分别建立射弹与典型等效目标的交汇模型,给出了典型弹目交汇参数的求解过程。进行案例分析,研究结果为撞击毁伤效果评估奠定了基础。 The spacecraft is divided into two categories: target and projectile, and the collision model of the two systems is studied. Based on the analysis of the target configuration, the target equivalent model is established based on the basic geometry and the mathematical description of the typical target is achieved. Considering the characteristics of the projectile structure, the actual missile guidance model was established based on the actual actual ratio. On the basis of this, the intersection model of the projectile and the typical equivalent target was established, and the solving process of the typical projectile cross parameters was given. Case studies were carried out and the results laid the foundation for the assessment of the impact of the damage.
