摘要:
为了获得某转管机枪在持续射击过程中拨弹阻力的变化规律,了解影响拨弹阻力的主要因素,降低弹链运动时拨弹力的大小,该文建立了持续高速供弹的弹链动力学模型,对弹链的运动进行了数值模拟。通过研究不同弹链长度与拨弹速度时拨弹阻力的变化情况,得出用波动理论得到拨弹阻力计算公式不能直接应用于描述持续供弹时拨弹阻力的变化规律,而弹链长度及拨弹速度突变量是影响拨弹阻力的主要因素,提出了减小转管机枪拨弹阻力的措施。研究结果为后续转管机枪供弹机构的改进提供了指导。
Abstract:
To obtain the change rule of links feed resistance in the process of firing in sequence on galting machine gun,and to know the main factors that influence links feed resistance and decrease the links feed resistance when ammunition belt moves,this paper establishes an ammunition belt dynamic model with ammunition feed at a high speed constantly to get numerical simulation on ammunition belt movement.On the basis of the study of change rule on links feed resistance with different lengths of ammunition belt and different links feed velocity,this paper concludes that the computational formula based on a wave theory cannot be applied to the change rule which describes continuous ammunition feed directly and that the ammunition belt length and links feed break-variable velocity are the dominant factors which influence links feed resistance.Some measurements are taken to reduce links feed resistance of galting machine gun.The research results provide guidence for further improvement of ammunition feed mechanism on galting machine gun.
