研究了长杆弹垂直侵彻有限厚靶时，着靶攻角对侵彻行为和终点效应的影响。定量分析了不同着速、长径比和弹材密度情况下，攻角对弹道极限速度的影响规律。并就某模拟弹等进行了理论计算和实验验证，结果令人满意。用本文建立的模型还可计算弹丸穿透靶板后的剩余速度，剩余弹长，剩余质量和塞块的厚度等。
The effect of target attack angle on penetration behavior and end point effect is studied when the vertical bar penetrates a finite thickness target vertically. The influence law of the angle of attack on the ballistic limit speed was quantitatively analyzed under different speeds, ratios of length to diameter and material density. The theoretical calculation and experimental verification of a simulated bomb have been made and the results are satisfactory. The model established in this paper can also be used to calculate the residual velocity, the remaining length of the projectile, the remaining mass and the thickness of the block after the projectile penetrates the target plate.
