| 摘要: |
| 设计了30mm半穿甲弹斜侵彻陶瓷/钢复合靶的弹道试验，采用高速摄像记录了弹靶作用过程，研究了弹着角、弹丸位移以及背板变形挠度的图像测量方法，通过仿真验证了该方法的可行性与准确性。基于高速摄像序列图像对弹靶作用过程进行了测量分析，结合试验数据研究了弹着角对半穿甲弹侵彻效能的影响。结果表明： 弹着角导致弹丸受靶板的不对称阻力作用，侧向力及侧向力矩使得弹丸在侵彻过程中不断偏转，表现为侵彻路径呈曲线；在相同速度条件下，随着弹着角的增大，侵靶时间延长，背板变形挠度减小，侵彻效能降低。 |

| Abstract: |
| The ballistic experiment of 30mm semi-AP obliquely penetrating ceramic/steel target is designed, and the image measurement method of impact angle, displacement and back plate deformation is proposed. The high-speed photography image sequences is measured based on digital image processing, and the effect of impact angle of oblique penetration is analyzed. The study shows that the impact angle will induce asymmetric effect in the projectile's penetration process, and the angle of yaw will gradually increase; under the same velocity condition, when the impact angle increases, the time of penetration will prolong, and the penetration performance will be reduced. |
