On the basis of presenting the new concept of firing stability of machine gun, a set of metric parameters of firing stability was put forward and its influencing factors were generalized. A virtual prototype model of machine gun was established and validated by means of ADAMS. The simulated re?sults approach to the experimental ones to a certain extent, which proved the model to be creditable and correct. The influences of the structure parameters and. the boundary condition on iinng stability were obtained by the simulation. Moreover, some suggestions used for improving firing stability were given. The proposed model provides a new method for the research on firing stability of machine gun.
