| 摘 要： | 在Alekseevski-Tate模型基础上, 理论分析了尖锥头长杆弹的界面击溃过程, 分别给出在锥头侵蚀阶段和弹身侵蚀阶段的弹体速度下降及质量侵蚀计算公式; 随后分析弹体的动能损失, 讨论半锥角对弹体动能损失的影响. 通过分析小子弹撞击陶瓷/金属复合靶板的例子, 验证了该理论的正确性, 并对比分析了尖锥头长杆弹与小子弹及平头长杆弹在界面击溃中动能损失之间的差异.

| Abstract: | Based on Alekseevski-Tate model,the present paper theoretically analyses the interface defeat of a conical-nosed projectile in its penetration process,and the corresponding formulae of velocity decay and mass erosion of projectile are conducted out.The effects of half apex angle on the kinetic energy loss of conical-nosed projectile are discussed.A ballistic impact case of a small armor piercing projectile(APP) against ceramic/metal composite target validates the present theoretical scheme.In addition,the c... |
