弹引系统以极大着角碰击半无限目标时的动力分析

Dynamic Impact Analysis of a Projectile/Fuze System Impacting Against a Half-Infinite Target with a Small Angle of Fall

摘要: 以弹引系统极大着角碰击半无限硬土或混凝土介质目标为研究对象,建立了弹目碰击时的物理模型和数学模型。通过分析弹目碰击时的空间几何关系,对弹目碰击过程的动态特性进行了分析和计算。

Abstract: Physical and mathematical models for the impact of a projectile on atarget are established with the assumption that the target is half - infinite in sizeand made of hard soil or concrete, and that the angle of fall very small.Through analysis, the spatial geometric relations of the impact and the dynamiccharacteristic of the impact process are considered in detail and calculated.
