| 摘 要： | 利用ANSYS/LS-DYNA3D有限元分析软件,选择适当的弹丸和土壤材料参数建立了弹丸侵彻靶板的有限元实体模型,在同一初始入射速度条件下,对弹丸不同入射角斜侵彻半无限厚土壤靶进行了数值模拟.结果表明当入射角不大于75°时不能出现跳弹现象,当入射角由小变大时,弹丸从侵入靶板演变为出现跳弹现象,随着入射角的增大,越容易产...

| Abstract: | Use ANSYS/LS-DYNA3D finite element analysis software, select the appropriate parameters of the projectile and soil materials to establish a projectile penetrating the target plate finite element solid model, the initial incidence rate in the same conditions, the oblique angle of incidence of the projectile penetration of different semi-infinitely thick target soil was simulated. The results show that when the angle of incidence is not greater than 75~ can not ricochet phenomenon occurs when the angle of incidence from small to large, the evolution of the projectile from the target plate for the emergence of invasive ricochet phenomenon, with the incidence angle increases, the more prone to jump elastic phenomenon. |
