Abstract The firearm percussion-ignition system is an important part of the firearmand its reliability directly affects the reliability of the whole firearm. In order to improve the reliability of the firearm percussion-ignition systemthis study takes a small-caliber rifle percussion-ignition system as the research objectestablished its finite element analysis modeland verified the accuracy of the simulation model by combining with the test results of the performance analysisAdopted the Isight platform to integrate TrueGridLS-DYNA and LS-PREPOST softwareand customized the parametric simulation platform of firearm percussion-ignition systemThe firing pin protrusionlocking clearanceprimer loading depthdiameter of firing pinthickness of primer cup and diameter of fire station head are selected as the main influencing factors of system reliabilitythe stress-strength interference model and Monte Carlo simulation method are combined to explore the influence of each influencing factor on the reliability of gun firing and ignition systemThe response surface model is used to fit the sample data to build up the reliability proxy model. The six main factors affecting the reliability of the system are selected as optimization variablesand the maximum reliability of the percussion-ignition system is taken as the goal to optimize the design of the percussion-ignition system structure. The results show that compared with the original designthe optimized design improves the reliability of the firearm percussion-ignition system by 19.59%.
