Calculation and analysis of rigid truncated-ogive-nosed projectile penetrating into concrete based on Teland force model

为对弹丸侵彻混凝土过程的高速录像试验数据进行分析,基于Teland计算模型,推导截卵形弹丸侵彻混凝土的位移时程计算公式。结果表明,计算数据与弹丸侵彻混凝土试验数据吻合良好。为侵彻试验高速录像数据的深入分析和截卵形弹丸侵彻混凝土深度计算提供依据。

In order to analyse the data of the projectile penetrating into concrete from the high-speed video.The displacement time history calculation formula based on Teland force model was deduceded for rigid truncated-ogive-nosed projectile penetrating into concrete.The new formula was experimentally verified by available data.The results show that the displacement time history predicted by the formula agrees well with high-speed camera measurements for projectiles into concretes.The analytical methods presented here will supply the foundation for deep analysis of high-speed camera data and penetration depth calculation of rigid truncated-ogive-nosed projectiles into concrete.
