Autofretted technology is used generally by high-pressure guns to enhance the strength of barrels. Mechanical properties of the autofretted barrel were studied based on the finite element software ABAQUS. For the open autofretted process, a simulation model of gun barrel was established and its accuracy was verified by comparing the simulation results with theoretical results. Various stress of autofretted gun in the firing process was simulated, and the best autofretted pressure was found. For the closed autofretted process, autofretted pressure was affected by the gap amount between the mold and the barrel.
