摘要
为了推广Forrestal侵彻方程的应用范围 ,基于球面空腔膨胀理论 ,用分析方法推导出弹丸垂直侵彻半无限厚地质材料的侵彻方程 ,建立了任意头形刚性弹丸侵彻地质材料的理论分析模型。试验数据和数值模拟结果表明 ,该模型能对地质材料侵彻过程中的弹丸速度、加速度和最终侵深等参数作出较为准确的预估。
By extending Forrestal's penetration model and based on the spherical cavity expansion theory, a resistance equation for arbitrary nosed projectile penetrating normally into semi-infinite geological materials was established. Comparison between the experimental data and numerical simulation indicates that the equation predicts very well for the velocity, acceleration and final penetration depth of the projectile penetrating into such materials.
