本文对有初始攻角长杆体垂直侵彻半无限厚靶的主要现象和过程作了分析。考虑了有攻角长杆体在侵彻过程的弹体破碎,弹渣非对称流动以及弹、靶材料性质对侵彻过程的影响。应用空穴膨胀理论的受力函数,根据变质量的动量守恒和质量变化的规律,建立了有攻角长杆体垂直侵彻半无限厚靶的简化计算模型,定量地描述了长杆体的初始攻角、长细比、弹杆材料对侵彻过程的影响规律。研究的速度范围是1000m/s~2000m/s,初始攻角的范围是0°-10°。将计算结果与实验结果进行了广泛地比较,对于高强度合金钢杆和高密度合金杆侵彻钢靶的侵彻深度具有合理地一致性。
In this paper, the main phenomenon and process of vertically penetrating the semi-infinite thick target with the initial angle of attack rod are analyzed. Considering the impact of the broken body, the asymmetrical flow of bomb residue and the nature of the projectiles on the penetration process of the long bar body with angle of attack during the penetration process. Based on the force function of cavity expansion theory and according to the law of conservation of momentum and mass change of variable mass, a simplified calculation model of vertically penetrating semi-infinite thick target with long angle of attack rod was established, and the initial attack Angle, slenderness ratio, the influence law of the rod material on the process of penetration. The research speed range is 1000m / s ~ 2000m / s, the initial angle of attack range is 0 ° -10 °. Comparing the calculation results with the experimental results extensively, it has reasonable consistency with the penetration depth of high strength alloy steel bar and high density alloy bar penetrating steel target.
