弹头飞行空间碎片碰撞概率建模与仿真

针对弹头飞行空间环境的日益恶化,建立了弹头与空间碎片碰撞概率的仿真模型。在分析空间碎片分布特征的基础上,根据建模需要描述了其数学运动规律,然后结合被动段弹道参数特点,推导建立了碰撞概率的数学模型。该仿真模型可以有效地计算出弹头在不同碎片密度环境下飞行的碰撞概率,并拟合出碎片密度与碰撞概率之间的关系曲线图。通过仿真计算证明了该模型的有效性,所得到的一些重要结论可为导弹武器的研制者和使用者提供一些借鉴。

Modeling and simulation of collision probability between flying warheads and space debris

Seeing that the space environment in which warheads flys has increasingly deteriorated,a simulation model of the collision probability between warheads and space debris is established.Based on analysing the distribution characteristics of space debris,a mathematics movement law of space debris is described according to the demands of modeling.Then,the mathematics model of collision probability is deduced with the consideration of the ballistic parameters' characteristics of the ballistic parameters in the passive segment.This simulation model can availably calculate the collision probability of warheads flying in the different density of space debris and draws up a relationship graph between the density of debris and the collision probability.The validity of this model is testified by the simulation calculation,and the significant conclusions can supply some references for missile weapon manufacturers or users.
