Research on the Influence of Matching the Muzzle Brake and Buffer Device on the Muzzle Disturbance of a Special Firearm

In order to study the impact of matching the muzzle brake and buffer device on the muzzle disturbance of a special firearm, this paper takes a special firearm as the research object, and based on the research method of rigid-flexible coupling dynamics, with the platform for fixing the firearm as the flexible body. ADAMS dynamic software is used to conduct simulation. The research plan includes the presence or absence of muzzle brakes, the presence or absence of buffering devices, buffering devices with different parameters, and the coordination between buffering devices with different parameters and muzzle brakes. The dynamic simulations and analyses for the aforementioned working conditions were proceeded respectively. By comparing the laws and differences from the simulation results, the optimal scheme which presents the minimum disturbance of the special firearm muzzle was determined. The research results indicate that the combined effect of muzzle brake and buffer device has a significant effect on reducing muzzle disturbance, and the combined effect of the two is better than the effect of their respective individual use.
