摘　　要：针对某型重机枪配用不同枪弹射击精度差异较大的问题,文中首先对该武器的自动原理及其优缺点进行了分析,以建立的某型重机枪枪身系统的动力学仿真模型为平台,对两种自动原理对武器射击频率及枪弹适配性问题进行了仿真研究,并通过与其它同口径机枪的试验结果对比分析,探讨了自动原理对武器动态稳定性的影响情况,为同类武器的结构设计提供参考。To solve problems of big accuracy difference in a certain type of heavy machine gun bullets, this paper analyzes the weapon automatic principle and their advantages and disadvantages. The dynamic simulation model of the gun system is established for simulating the effect of two automatic principle on weapons shooting frequency and bullets matching problems. Through comparing with test result analysis of the other same caliber machine gun, the impact of automatic principle on weapon dynamic stability is discussed to provide a reference for the structure design of similar weapons.
