摘要:
为确保现行枪械定型试验射击规范的技术可行性,从机枪枪管寿终机理分析入手,对枪管铬层开裂的原因及热作用与铬层开裂的相关性进行分析。通过大量试验研究,得出射击规范与枪管温度的相关性关系。通过冷却介质对枪管铬层的热冲击破坏作用的分析及模拟试验,确定了热枪管投水冷却的合理时机即枪管内膛温度上限值。给出了不同机枪射后至水冷前的空冷时间下限值。为枪械定型试验射击规范的制定提供了理论依据。
Abstract:
To insure the technical feasibility of the active shooting criterions in approval tests on firearms, the reason of the chrome layer of barrels being ruptured and the relat ivity of the hot action and the chrome layer fission are analyzed starting with analyzing lifet ime-ended mechanism of machine-guns. barrel. The relativity of the shooting criterions and barrel temperature is obtained by a lot of tests.The reasonable occasion of barrels being put into water, namely, the upper limit values of temperature in barrels. inner-chamber are ascertained by analyzing the hot impact and breakage action of cooling mediums to the chrome layer of barrels as well as by simulation tests. The lower limit values of air-cooling time from after-firing to before-water-cooling about different machine- guns are given. The results provide theoretical gists for establishing reasonable shooting criterions in approval tests on firearms.
