Abstract

For the study of vibration reduction performance and firing accuracy improvement of a new type of arc tripod structure, an accurate rigid-flexible coupling multi-body model of a machine gun system is then established based on ADAMS software as well as related experimental data. The muzzle dynamic responses of the machine gun system with different tripod structure were compared under the same conditions. Based on the exterior ballistic theory and its boundary conditions, the shot dispersions are obtained with a firing distance of 100 meters. The results show that the muzzle vibration is mainly occurs in the vertical direction(y axis). In this direction, the peak amplitude averages of the displacement, velocity and firing angle decreased by about 27.8%、25.8%、31.1% respectively. And finally the radius of 100%, 50% scattered circle decreased by 33.6%、23.2% respectively. The arc tripod structure can effectively improve the firing accuracy of the machine gun system.
