摘要
为了更有效地增强线性自锻破片对穿甲弹的干扰作用,对线性自锻破片切割杆式穿甲弹的最佳角度展开研究。运用LS-DYNA软件对线性自锻破片切割杆式穿甲弹的过程进行了数值模拟研究。通过分析线性自锻破片对不同速度穿甲弹的最佳切割角度,以及穿甲弹被切割后对后效靶板的毁伤效能,得出了线性自锻破片对穿甲弹的最佳切割角度为90°时,穿甲弹的变形程度最大,对后效靶板的毁伤效能较差,残余弹体的侵彻能力最低。该研究为主动防御系统的结构设计提供了参考依据。
In order to improve the interference effect of the linear self-forging fragments on the penetrator more effectively,a study was made of the optimal cutting angle of linear self-forging fragments cutting rod penetrator. The numerical simulation of linear self-forging fragment cutting rod penetrator was carried out through LS-DYNA software. Through the analysis of linear self-forging fragments of different speed rod optimum cutting angle,and after-effect target damage effect when the long penetrator was cut,it is concluded that the linear self-forging fragment of long rod projectile optimum cutting angle is 90°,resulting in the maximum degree of deformation of rod,poor efficiency of target damage effect and residual projectile penetration capability at the lowest. At the same time,it provides a reference for the structure design of active defense system.
