| Abstract: | In order to optimize the frequency matching of machine gun, to consider the firing frequency of machine gun, the virtual prototype for gun body of machine gun is established. Take diameter of gas port, section area of piston, mass of bolt carrier, bolt mass and buffer spring stiffness of barrel as optimization variables, the firing frequency for better matching of machine gun is defined by making use of the dynamic response testing result of machine gun and the optimization theory of firing frequency. At last, sequential quadratic programming optimizes the automatic structural parameters. |
