子母弹中心管式静态抛撒仿真技术研究

摘要
以某型子弹药为研究对象,基于合理假设,结合经典内弹道学理论,建立静态抛撒过程子弹药内弹道数学模型;运用任意拉格朗日-欧拉(ALE)算法,利用有限元方法对静态抛撒内弹道过程进行数值模拟仿真,得出子弹药加速度、速度、位移的变化规律,实现对中心管式抛撒系统的优化设计,得到合理的子弹药抛撒运动参数;该模型同样适用于采用中心管抛撒方式的其他弹药,并且可与子弹药抛撒外弹道模型相结合,建立子弹药抛撒全弹道数学模型,对子弹药全弹道过程进行分析。
Taking a certain type of submunition as the research object,its internal ballistic mathematical model during static dispersing process was established based on reasonable hypothesis and classical internal ballistics theory. Random Lagrangian euler( ALE) algorithm and finite element method were used to conduct numerical simulation of the scattering process. The change law of acceleration,velocity and displacement of submunition was obtained. The optimal design of the central tube type dispersing system can be realized to obtain the reasonable submunition dispersing motion parameters. The model is also applicable to other ammunition using the central tube dispersing method. And combined with the submunition dispersing external ballistic model,the full ballistic mathematical model of submunition during dispersing process can be established to analyze the full ballistic process.
