摘要
为解决大威力狙击步枪减后坐及轻量化问题,提出了一种大口径狙击步枪减后坐方案,建立了该大口径狙击步枪减后坐方案虚拟样机仿真模型,通过仿真计算揭示了枪管和自动机质心的位移、速度随时间变化规律及发射过程中发射系统内部主要载荷变化规律;分析了缓冲簧刚度、预压力及膛口制退器制退效率对大口径狙击步枪最大后坐力和自动机运动周期T的影响.研究结果为该类大口径狙击步枪性能预测和性能优化奠定了技术基础.
To solve the problems of reduction recoil and lightweight of high-power sniper rifle,a reduction recoil program of large-caliber sniper rifle（LCSR） was presented,and the virtual prototype simulation model of LCSR was established.The rule of the displacement and velocity of the barrel and automat centroid varying with time were revealed,and the main load variation within the launch system was also revealed.The effect of buffer spring stiffness,pre-pressure and recoil device efficiency of muzzle recoil on LCSR maximum recoil automat motion cycle T were analyzed.The research results provide a technological basis for performance prediction and performance optimization of this kind LCSR.
