Mechanical model of the grooved-tapered projectile penetrating concrete targets

  • 摘要: 利用混凝土材料的动态球形空腔膨胀理论,建立了针对刻槽弹体的低速花瓣形受力模型和高速圆孔形受力模型,并采用这两种模型计算了刻槽弹体侵彻混凝土的侵深。结果表明:当初速低于1 000 m/s时,运用低速花瓣形受力模型计算得出的侵深和实验值的误差小于11%;当初速高于1 000 m/s时,运用高速圆孔形受力模型计算出的侵深和实验值的误差约为20%。综合实验过程和实验误差分析可知,建立的刻槽弹侵彻混凝土受力模型可用于刻槽弹对混凝土的侵彻能力分析。
