射击比赛一直以来都是奥林匹克运动会的正式项目,该项目对枪械和子弹的物理尺寸都有严格的规定。在射击比赛中,子弹的火药装填量是影响运动赛成绩的重要因素之一,如何对其进行无损检测,是各个射击队长期以来迫切期盼解决而未能解决的难题。为保证中国国家射击队所用子弹的质量,在对多种无损测量方法对比之后,使用X线和中子照相2种方法,分别对发令枪子弹、奥运射击子弹和几种装有不同类型火药的子弹做了对比测量,有效地提高子弹的可信度。最后对测量结果进行了理论对比分析,总结得出子弹火药含量无损检测的可行方法。
The shooting competition has long been an official project of the Olympic Games, which has strict rules on the physical dimensions of firearms and bullets. In the shooting competition, the bullet charge of gunpowder is one of the important factors that affect the performance of athletes. How to carry out non-destructive testing of the bullets has long been an urgent problem that various shooting teams are looking forward to to solve and can not be solved. In order to ensure the quality of the bullets used by the Chinese national shooting team, after comparing a variety of non-destructive measurement methods, two methods of X-ray and neutron radiography were used, respectively, for shooting bullets, Olympic shooting bullets and several bullets with different types of gunpowder Made a comparative measurement, effectively improve the credibility of the bullet. Finally, the theoretical analysis of the measured results, concluded that the gunpowder content of non-destructive testing feasible method.
