摘　　要：针对长杆弹垂直侵彻半无限厚靶板的问题,理论上分析了影响弹体侵彻效率的主要因素,并就其对长杆弹归一化侵彻深度的影响规律及机理进行了系统的探讨,得出了长杆弹截面形状、头部形状、长径比、入射速度、弹靶材料密度比、弹靶材料泊松比、弹靶材料强度在长杆弹侵彻过程中的影响机理和其对最终归一化侵彻深度的影响规律。这些结论能够对长杆弹、防护装甲以及防护工事的设计提供一定的科学依据。As for long-rod penetrator vertically penetrating semi-infinite target, the principal influence factors on penetration efficiency were analyzed in theory, and the influence rules and the influence mechanisms of them on the normalized penetration depth were discussed. The influence rules of the factors such as cross-section shape, nose shape, aspect ratio, density ratio between penetrator and target, incident velocity, Poissong ratio, strength of penetrator and target on the penetrating process and terminal penetration efficiency were obtained. These can provide a reference for optimization design of long-rod projectile, protective armor and defense works.
