| Abstract: | Based on the elastic-plastic contact finite element theory,inertial bayonet-chamber process of a projectile was analyzed,and its finite element model was built.The inertial bayonet-chamber process with 1~4 m/s was computed,the elastic-plastic deformation of the band and the dynamic response of the projectile was obtained and the influence of the friction coefficient on the computed results of the inertial bayonet-chamber process was analyzed. |

| Keywords: | projectile band inertial bayonet-chamber dynamics |
