前冲击发减后坐方案对某榴弹发射器射击密集度的影响

Analysis of Impact of Advancing Ignition on Pattern Density of Automatic Grenade Launcher

设计了一种将前冲击发应用于某高初速榴弹发射器的减后坐方案。基于ADAMS建立了刚柔耦合发射动力学模型,以膛口为测量对象仿真分析了膛口跳动情况,研究了身管振动的影响规律,并对各项初始扰动量进行了分析处理,确定了射击密集度的计算方法,获得了武器系统高精度发射性能的前冲击发结构评估参数,为新型高初速低后坐榴弹发射器的优化设计提供了理论基础。

A recoil reduction scheme applying advancing ignition to a grenade launcher with high initial velocity was designed.To solve the problem of falling accuracy of shooting caused by barrel floating in this scheme,a dynamic model of rigid-flexible coupled emission was established by using ADAMS software.Taking the muzzle as measurement object,the beating behavior of the muzzle was simulated.The impact rule of the barrel vibration was discussed,and the various initial disturbance quantities were analyzed and processed.The calculation method of the shooting intensity was determined,and the structural evaluation parameters of the weapon system’s floating device with high-precision emission performance were obtained,which provides a theoretical basis for the optimal design of the new grenade launcher with high initial velocity and low recoil.
