弹丸对钢板的半侵彻作用特性研究

 随着现代高新技术的发展提出了对弹丸半侵彻（PEP）的研究，通过弹丸的半侵彻作用使其稳定嵌立于目标靶上，并由其外露部分形成障碍或感应目标伺机作用、或作为受力承载点等方式实现特殊用途。针对新结构弹头开展了弹靶半侵彻过程的数值模拟和靶材流动特性研究，采用量纲理论获得了弹丸半侵彻靶板的主要无量纲组合参量，获得了弹丸侵彻与反弹阶段靶板形变与弹靶系统能量分配特性，并对半侵彻作用机理进行了初步的探讨。最后通过炮射实验验证了实现稳定嵌立于靶板的可行性。

Study on Characteristics of Partial Penetration of Projectile into Steel Panel

Study on partial embedment of projectile (PEP) is put forward with the development of modern science and technology. The outer part of PEP standing stably can form an obstacle or induce the selective object to attack it by waiting for the proper chance, or act as the loading point to realize the special application. The research on a new nose shape projectile was carried out by the numerical analysis on process and characteristics of PEP and material testing of rheological behavior. Meanwhile, the main dimensionless group parameters were obtained by dimensional method. The deformation of target and energy evolution of the whole system in the forward and rebound phases of projectile were analyzed. The exploratory development work on mechanics of the PEP action was performed. Ultimately, PEP on steel panel was verified by artillery experiment.
