摘要 为了提高长杆弹的侵彻效率,针对长杆弹对半无限靶板的垂直侵彻行为,分析了影响侵彻深度的主要因素,并利用经验公式和商业数值软件研究了各因素对侵彻深度的影响规律和机制。研究表明:当弹体的总动能一定时,存在一个长径比、入射速度、弹体旋转速度,使得该种长杆弹的侵彻深度达到最大值,并对已知总动能的情况下如何求解和优化设计这些参数进行了说明。 To improve the penetration efficiency of long-rod penetrator, in view of long-rod penetrator vertically penetrating semi-infinite target, key factors affecting the penetration depth were analyzed, and effect mechanism of the factors on penetration depth was studied with empirical formula deduced from experiments and numerical simulations. The results show that if initial kinetic energy of the long-rod penetrator is constant, the optimal values of aspect ratio, incident velocity, rotation velocity exist, when the maximum depth is obtained, and as the values of these factors change, the penetration depth would decline. How to obtain and optimize these values was provided.
