摘要
PELE是一种基于新型作用机理的弹药,能使目标产生明显的横向效应,对靶后目标形成有效的杀伤。为研究着靶角对PELE横向效应的影响,对不同着靶角下PELE侵彻靶板的过程进行了数值分析。结果表明:着角对PELE横向效应影响显著。当着角在0～60°,随着着角的增大,破片最大径向速度增大,散布面积增大,破片数量增多,横向效应增强;当着角大于60°,随着着角的增大,PELE横向效应逐渐丧失;当着角在30～60°,PELE横向效应和后效毁伤性能最佳。
PELE is a projectile based on a novel kind of damage mechanism, which produces obvious lateral efficiency on the target and damages for objects behind the target. In order to analyze the influence of impact angle on PELE, numerical simulations at different impact angle were carried out. The results indicate that the impact angle is closely related to the lateral efficiency of PELE ; when the impact angle varies from 0° to 60°, the scattering area, number and maximum radial velocity of fragments increase accordingly, and the lateral efficiency of PELE is therefore enhanced; while the impact angle is larger than 60°, with the increment of impact angle, the lateral efficiency of PELE disappears gradually. As the impact angle is between 30° and 60°, the lateral efficiency and the after effect damage efficiency of PELE perform best.
