大口径机枪浮动技术试验研究

The Experimental Study on the Floating Technique of Large Caliber Machine Gun

目的 检测弹簧液压式浮动机的浮动性能和实际效果 .方法 在实弹射击条件下 ,分别对浮动和不浮动机枪进行自动机动态测试和射击精度试验 .结果 获得了机枪连发射击时的位移、后坐力和射击精度值 .结论 所设计的弹簧液压式浮动机实现了机枪的稳定浮动 ,并可大幅度减小后坐力 ,显著提高机枪的射击精度 .

Aim: To examine the floating performance and actual effect of hydraulic-spring floating machine. Methods: The dynamic test on automatic mechanism and firing precision is accomplished for the floating machine gun and buffering machine gun in ball firing. Results: The displacement, recoil-force and firing precision are attained in a running fire. Conclusion: It can be verified to make machine gun float steadily by use of the designed hydraulic-spring floating machine and remarkably reduce the recoil-force and improve the firing precision.
