浮动状态下机枪动态性能测试实验

本文针对某高射机枪用弹簧液压式浮动机.为了解采用该浮动机后机枪的后坐阻力、位移等性能参数,建立了测试系统并进行了相关的试验和测试.结果表明,采用该弹簧液压式浮动机,可以实现机枪的浮动射击,并且具有较高的浮动稳定性;机枪射击时的后坐阻力和前冲力都得到了大幅度降低,可有效降低架体的受力和变形,对提高射击精度是有利的.

The Experiment and Test on Dynamic of Floating Mechanisms of Machine Gun

In this paper, the related experiment and test are carried out to get recoil force and displacement performance parameters of the spring-hydraulic floating mechanisms used in certain antiaircraft machine gun. By analyzing experimental data, we can see the use of spring-hydraulic floating mechanisms could actualize floating shoot of the machine gun, and the gun＇s floating stability will be better, furthermore, when shooting, the recoil force and the onward force of the machine gun will be reduced sharply, in accordance; the force on the trestle and the distortion of it will be reduced effectively, these are advantageous to improving the shooting precision.
