某通用机枪连发射击稳定性研究

Research on Firing Stability of General Machine Gun

探究某通用机枪射击过程中枪口跳动而影响射击稳定性的问题,提出了一种改进枪管结构的方法来提高射击稳定性。首先建立了人枪动力学模型并进行仿真,分析枪口跳动的原因以及增强设计稳定性的方法,然后在改进枪管结构即开喷气孔后再对机枪进行运动学仿真模拟。对比枪管结构改进前后枪管与两脚架的跳动位移的情况,可知该方法是一种可行的方案,可以明显提高机枪射击稳定性。

This paper discusses a general machine gun＇s firing stability at its firing and puts forward a way to change the barrel struc- ture to improve the firing stability, it also establishes the dynamic model of the gun and man, analyzes the reasons of its unstability and proposes a method of enhancing the firing stability, and then simulates the kinetic model for the improved structure. Comparing the barrel and bipod＇s beating displacement situation before and after the change of the barrel, this method is practicable and can be used to significantly improve the firing stability.
