基于X光摄影的轻武器杀伤元侵彻明胶效应研究

Research of Penetration Effect of Small Arms Lethal-Element Penetrating Gelatin Based on X-ray Photograph

为研究轻武器杀伤元侵彻明胶效应,诸如靶标后的弹道轨迹和瞬时空腔,利用X光摄影法进行正交拍摄以获得2维图像,并采用加装视场光阑的方法解决了实验过程中X光图像发生的正交干扰问题.X光正交拍摄轻武器杀伤元侵彻靶标的实验结果表明,加装视场光阑的方法可以获得画质良好的图像.根据实验拍摄到的明胶空腔的图像,分析了杀伤元侵彻明胶的侵彻效应.实验结果表明,同一发弹丸在靶标后挡板上撞击产生了近似圆形和长锥形的2个痕迹.

To study the effect of small arms lethal element penetrating gelatin,such as trajectory and instantaneous cavity after the penetration,the method of X-ray photograph was used to conduct the orthogonal graphs to obtain two-dimensional images.In the experiment,the problem that the orthogonal interference occurred on the images of X-ray photographs was solved by attaching field diaphragms.The experimental results of small arms lethal-element penetrating the gelatin based on X-ray photograph indicate that the distinct images can be obtained by attaching field diaphragms.The penetration effect of lethal-element penetrating the gelatin was analyzed based on the photographed images of gelatin cavity in the experiment.The experimental results indicate that after the same projectile impacting the baffle at the back of target,two kinds of tracks appear：an almost circule and a long taper.
