To prolong the life of cartridge retaining pawl and link stopper in a gun cartridge retaining Mechanism, three compression springs stiffness are reduced via design study and optimization design based on dynamic analysis. Presenting the load of shell on a typical stage while entering-bore, differential equations of motion in this mechanism are established. With translational velocity of shell as the design variable, a design research and simulation analysis are made. And the relationship between shell velocity and proper shell-feed is acquired. An evaluation function is built using springs stiffness with preference-selection. With this evaluation function as the optimum objective, spring stiffness as design variables, and proper shell-feed as constraint condition, the minimum of three spring stiffness is obtained after calculation. The results indicate that compared with the original design parameters optimization results, are significantly improved with the stiffness decreased separately by 20.27%, 11.99% and 6.86%.
