Abstract
For a sniping rifle, the vibration of the barrel had important influence on its firing accuracy. The dynamic characteristic of different sniping rifle’s barrels was researched. Based on the modal analysis, the transient analysis of different morphological structure on finite element software ANSYS, and dynamic characteristic of barrel under powder gas force was researched. The displacement response and velocity response of the centrality of gunpoint was obtained. The result proved that the inflexibility of cone barrels was bigger than cylinder barrels. For cone barrels, the displacement response and velocity response of the centrality of gunpoint was smaller. These results provide the theoretical basis for the design of the barrel of the sniping rifle.关键词
