摘要
为研究某单管高射机枪枪管寿命趋势,进行了枪管综合寿命试验和数据采集,获得了一套完整的性能衰减数据.对采集的数据进行整理,结合历年来生产验收的试验数据,分析了初速下降率、散布精度、枪管烧蚀和膛口尺寸随射弹数的变化规律及产生的原因,获得了关于该大口径机枪枪管寿命变化趋势及其影响枪管寿命因素的新认识,为该大口径机枪的验收、使用与维护规范的修改及改型设计提供了试验依据.
To study the performance decay of an antiaircraft machine gun, a life test for the barrel of the gun was done and detailed data was obtained. A set of performance decay data of life time was presented. Based on the analysis of the experimental data and product acceptance test data of previous years, the changing law and the cause of the loss in the muzzle velocity, bullet dispersion accuracy, barrel erosion and changing patterns of bore dimension during firing rounds were analyzed. A new understanding of performance decay and its influence of a large caliber machine gun barrel in lifetime were presented. This investigation is valuable for the modification of the acceptance test method, operation and maintenance＇s regulation and production design of the large caliber machine gun.
