METHOD FOR GUN BARREL MANUFACTURE USING TAILORED AUTOFRETTAGE MANDRELS |
摘要 |
A method of manufacturing a monobloc gun barrel by calculating an optimal residual stress profile and then applying tailored autofrettage mandrels which are mechanically pressed down the bore of a large caliber barrel, the mandrel size optimized to create a residual stress distribution on the interior of the bore within the design constraints imposed by the worst-case heat flux scenario.
