Abstract

Abstract: A rigid-flexible coupling multi-body dynamic model of a new large caliber machine gun based on floating principle is established, in which the influences of soil and human body on machine gun were considered. The dynamics simulation of the machine gun with muzzle brake is conducted, and the simulated results are compared to the experimental results, and the availability of the proposed model is verified. The range of values allowed for the muzzle brake efficiency of machine gun based floating principle is obtained. The study results show that the proposed rigid-flexible coupling multi-body dynamic model including muzzle brake is accurate and reliable, and the efficiency of the designed muzzle brake is 35.9%. The theoretical range of values for the muzzle brake efficiency of machine gun is 22.5~50.0%.
