摘要
为研究车载转管机枪后坐力变化规律,依据内弹道理论建立三管12.7 mm转管机枪内弹道数学模型,运用V B编写程序得到枪管膛压曲线;应用刚柔耦合系统动力学理论建立车载转管机枪武器系统虚拟样机,依次分析枪身与架座之间分别采用有预压力双向缓冲器、有预压力单向缓冲器、无预压力双向缓冲器3种连接方式对后坐力、机匣前冲与后坐位移的影响。结果表明,有预压力双向缓冲器可有效降低并快速衰减后坐力。
In order to study the changing law of the recoiling force variation of the vehicular gatling gun,the mathematic model of three-tube 12.7 mm vehicular gatling gun internal ballistic trajectory is built according to the theory of internal ballistics,and the gun barrel pressure curve is obtained by using VB programming. The rigid-flexible coupling system dynamics theory to build the virtual prototype of the vehicular gatling gun weapon system is used. Then the effect of using pre-pressure bi-directional buffer,one-way buffer with pre-pressure and two-way buffer without pre-pressure in barrel and frame on recoil,box forward stroke and recoil displacement are analysed. The results show that the bi-directional buffer with pre-pressure can effectively and rapidly reduce the recoil force and launch steadily,an effective technical method and reference for the research on vehicular gatling gun weapon system is provided.
