An analytic model of penetration for oval-nosed projectile penetrating into pre-drilled target

  • 摘要: 以破爆型串联战斗部后级随进弹对预开孔靶侵彻过程为研究对象,基于锥形预开孔和库仑摩擦模型,发展完善了包括扩孔/开坑和稳定侵彻的卵形弹体侵彻预开孔靶理论模型。分别对该模型在侵彻脆性和弹塑性靶体的有效性进行了实验验证。利用该模型分析了弹头曲径比、预开孔直径、预开孔形状等对侵彻结果的影响。研究结果表明:发展完善的模型计算结果与实验数据吻合较好。柱形开孔情况下,侵彻速度、弹头曲径比及相对孔径同侵彻深度呈正比;在侵彻容积相同的条件下,弹体侵彻预开锥孔的侵深结果与锥角及相对入孔孔径变化关系较大。
