Contact Stresses during Roller Rolling of Heat-Exchange Tubes

Abstract:

A technique for studying contact stresses in the connection of heat-exchange tubes with tube sheets using roller rolling is described. Formulas for the determination of contact stresses, taking into account the formation of local deformation of the tube due to force action of each roller and features of axial movement of the tool spindle are given. Calculation was based on the assumption of medium continuity, known relations between normal stresses and deformations, as well as experimental oscillograms of the process.
