| 摘 要： | 为了探讨薄板斜穿甲的破坏机理和弹体剩余速度，采用非线性动力学程序AUTODYN分析了截锥形弹体不同入射角度冲击下薄板的破坏模式，以及入射角度对靶板吸能和弹体剩余速度的影响，提出了靶板梨形孔的破坏模式．数值计算表明弹体斜穿甲时靶板吸收的能量与垂直穿甲时相差不大，斜穿甲时弹体在靶板上有滑移现象，并在高斜角低速撞击时弹体发生明显偏转，靶板也表现出不同的破坏模式。

| Abstract: | In order to explore the failure modes of target and the terminal of projectile with the oblique penetrating, the impact numerical analysis was conducted using dynamic nonlinear process AUTODYN. The failure modes of thin plate impacted by truncated cylindroconical projectile with different angle of incidence were studied. Energy absorption of target and residual velocity of projectile were also exam- ined. A failure mode of pyriform hole was put forward. The results of this numerical investigation show that ... |
