摘要
以机枪射击动态稳定性理论为基础,以建立的某型重机枪动力学仿真模型为平台,针对该武器配用不同枪弹射击精度差异较大的问题,采用仿真和试验数据相结合的方法,分析了武器枪弹适配性问题的原因,通过调整武器导气装置的结构,改变配用不同枪弹射击频率相差较大的问题,改善了武器射击频率与固有频率的匹配关系,提高武器的枪弹适配性。
In this paper, with the machine gun fire dynamic stability theory as the foundation, with the dynamic simulation model of a certain type of heavy machine gun is established as the platform, aiming at the problem of different weapons with bullets difference accuracy, using the method of combining simulation and experimental data, analyzed the reason of weapon bullet matching problems, by adjusting the structure of air guide device of weapons the change, with different bullet shooting frequency difference between the larger problem, improve the matching relation of weapon firing frequency and natural frequency, improve weapon bullet suitability.
