Abstract

This paper focuses on establishing the dynamic model describing the motion of bolt-carrier for the amphibious rifles when shooting under-water. This dynamic model is applied for the 5.56 mm amphibious rifle designed by the research project of the ministry of defense. The model in this paper can be applied to study the influence of the structural parameters in rifles on the operation of the automatic system during shooting under-water and contributing to the adjustment, optimization designs.
