摘要
针对大口径机枪射击稳定性低的问题,提出一种利用膛内火药气体能量来减小枪口跳动的稳定控制装置;鉴于枪管在稳定力作用下会发生变形,采用一种支架装置来加强枪管的刚度;基于刚柔糅合、多柔体动力学理论,以ADAMS、Matlab软件为平台,对改进后的机枪进行仿真,枪口跳动的最大位移值下降了46%,脚架振动的最大位移值下降了41%,射击稳定性得到明显提高。
Aiming at the problem of low firing stability of large caliber machine gun, a stability control device using the energy of the propellant gas was proposed to reduce the jump of the muzzle. Considering the deformation of the barrel under the force of stability control device, a bracket device was applied to improve stiffness. The machine gun that has been changed was simulated to verify the firing stability of machine gun by using ADAMS and Matlab software based on rigid-flexible coupling and mufti-degree flexiblebody dynamics theory. The maximum displacement value of the muzzle is decreased by 46%. The maximum displacement of tripod vibration is decreased by 41% , and the firing stability improves a lot.
