【摘要】 为改进和提高穿甲弹的侵彻性能 ,给弹丸设计过程中的参数优化提供理论依据 ,利用非线性动力有限元分析程序 ,对高速弹丸侵彻均质靶板进行了数值模拟。通过对弹丸侵彻靶板各种影响因素的数值模拟以及对计算结果的分析表明 ,弹丸对靶板的侵彻能力不是取决于它的整体功能 ,而是当靶板参数和弹材固定时 ,可用弹丸初始横截面积比动能来标志。数值模拟结果与现有的经验公式符合很好。更多还原

【Abstract】 In order to provide the theoretical foundation for design and construction improvement of the projectile, numerical simulation of projectile penetration at high speed was implemented with lagrange algorithm. According to the analysis of several effects on penetration in simulation results, the penetrating capability of the projectile is not decided by its kinetic energy but the kinetic energy vs its cross section area, when the other conditions are the same. The simulation results conform relatively well to some experience formula.更多还原
